Indeed, in other embodiments, the materials of the first abutting portion 423 and the second abutting portion 433 may be other, and are not specifically limited herein as long as the above-mentioned effects can be achieved.

In order to reduce the loss of force, the first swing link 422 and the second swing link 432 may have an alternating point in the alternating process, and in order to prevent the first swing link 422 and the second swing link 432 from having mutual influence at the alternating point, in the present embodiment, the rotation trajectory of the first swing link 422 is tangent to the rotation trajectory of the second swing link 432 or has a gap therebetween. That is, at the time of the alternate point, the outer sides of the first abutting portion 423 and the second abutting portion 433 touch or have a gap, so that the first swing link 422 and the second swing link 432 do not abut against each other to stop the rotation and then stop the position during the rotation process.

Correspondingly, the sum of the diameters of the rotation paths of the first swing link 422 and the second swing link 432 is greater than or equal to the distance between the initial position a and the energy storage position B, wherein the rotation paths of the first swing link 422 and the second swing link 432 refer to the path of one rotation of the first swing link 422 and the second swing link 432. The purpose of this is to: the first swing link 422 and the second swing link 432 push the connecting seat 34 to the maximum extent, so that the plunger 32 maximizes the amount of gas compression in the cylinder 31, and the nail gun 100 has stronger power. In order to keep the first link 422 and the second link 432 from being obstructed during the movement, the lowest point of the guide lever 35 is higher than the highest point of the driving mechanism 4 in the height direction of the nail gun 100.

Referring to fig. 6 to 9, the moving process of the first swing link 422, the second swing link 432 and the connecting seat 34 is specifically as follows: when the connecting seat 34 is located at the initial position a, the second abutting portion 433 of the second swing link 432 does not abut against the connecting seat 34. The driving assembly 41 drives the first gear 421 to rotate, and then drives the second gear 431 to rotate, so as to drive the second swing link 432 to rotate, and then the second abutting portion 433 abuts against the connecting seat 34 to push the connecting seat 34 to move towards the cylinder 31; when the second swing link 432 reaches the alternating point, the first abutting portion 423 of the first swing link 422 and the second abutting portion 433 of the second swing link 432 abut against the connecting seat 34 at the same time, and at this time, the second swing link 432 moves to a side away from the cylinder 31. The driving assembly 41 continues to drive the first gear 421 to rotate, so that the second abutting portion 433 moves towards the direction close to the cylinder 31, and then drives the connecting seat 34 to continue to move towards the cylinder 31 until the connecting seat 34 moves to the energy storage position B, where the first swing link 422 is parallel to the guide rod 35. After the first swing link 422 is separated from the connecting seat 34, the connecting seat 34 flies out at a high speed under the driving of the plunger 32, and at this time, the second abutting portion 433 of the second swing link 432 is located outside the guide rod 35.

In order to prevent the connecting seat 34 from impacting the main housing 11 under the action of force to cause larger reaction force by the connecting seat 34 when moving from the energy storage position B to the initial position a at a high speed, and then acting on the piston column 32 to influence the tightness between the piston column 32 and the cylinder 31, weaken the energy storage effect of the energy storage device 3, reduce the striking force of the nail gun 100, and prevent the main housing 11 and the connecting seat 34 from being damaged under the action of the force, and reduce the service life of the nail gun 100, the nail gun 100 further comprises a protection mechanism 5 arranged at the initial position a, wherein the protection mechanism 5 comprises a cushion hoop 51 arranged on the circumferential surface of the main housing 11 and a cushion 52 arranged on the main housing 11 and facing the cylinder 31, and the cushion 52 is arranged close to the initial position a.

In summary, the following steps: the guide rod 35 and the plunger type energy storage device 3 are arranged, so that the moving stability of the plunger 32 is improved, the plunger 32 only moves along the axial direction of the cylinder 31, the rotation and the deviation of the plunger 32 are prevented, the gas compression amount in the cylinder 31 and the energy storage effect of the energy storage device 3 are improved, and the service life of the nail gun 100 is prolonged.

Referring to fig. 18 to 40, the nail gun 100 of another preferred embodiment of the present application is generally applied to a construction scenario for driving fasteners such as nails, tacks, staples, etc. into a workpiece to fix the workpiece, and the application scenario of the nail gun 100 is not particularly limited.

Referring to fig. 18, the nail gun 100 includes a housing 10, an energy storage mechanism 20 disposed in the housing 10, a driving mechanism 60, a motor 30, and a striking mechanism 50 at least partially disposed in the housing 10. The material of the casing 10 may be plastic, metal, etc., and is not particularly limited herein, depending on the actual situation.

The housing 10 includes a main housing for accommodating at least a portion of the energy storage mechanism 20 and the driving mechanism 60, and a holding housing connected to the main housing for holding the main housing, and the holding housing is used for accommodating the wires therein for convenient layout. One end of the holding case is connected to the main case, and the other end is connected to the magazine 70 to form a "D" shape, which is convenient for a user to hold.

In order to prevent the user from slipping during the holding process, the holding shell may further be provided with an anti-slip member, the anti-slip member may be a rubber member sleeved on the holding shell, or may be a protruding point protruding outward from the outer surface of the holding shell, and the anti-slip member is not specifically limited herein, and is determined according to actual conditions.

The main housing is generally divided into at least two main housings, two main housings are assembled to form a receiving cavity, and the energy storage mechanism 20, the driving mechanism 60 and at least a part of the striking mechanism 50 are received in the receiving cavity, so that when a device in the main housing fails, the main housings are conveniently detached to repair and replace the device. The connection between the at least two main housings can be realized by clamping, bonding, welding or fastening, etc.

The energy storage mechanism 20 is used for driving the striking mechanism 50 to strike after energy storage, so that the striking mechanism 50 has strong impact force in a moment, and a fastener can be struck into a target object. Which is generally a cylinder or the like. However, the volume of the cylinder is large, and the energy storage mechanism 20 is disposed in the casing 10, which makes the whole casing 10 large in volume. Therefore, in order to prevent the volume of the casing 10 from increasing, in the present embodiment, the energy storage mechanism 20 is a nitrogen spring, which has the characteristics of small volume, large elastic force and impact force.

Specifically referring to fig. 18 and 19, the nitrogen spring generally includes a cylinder 201 disposed in a housing, a gas filled in the cylinder 201, a plunger 202 moving relative to the cylinder 201, and a sealing member disposed between the cylinder 201 and the plunger 202 and fixed relative to the cylinder 201. The cylinder 201 is provided with a first port 2011 and a second port 2012 remote from the first port 2011, wherein the first port 2011 is disposed proximate to the striking mechanism 50.

The striking mechanism 50 includes a striking element 501 for striking a fastener and a connecting seat 502 for connecting the striking element 501 and the plunger 202, and mounting holes are respectively formed at two sides of the connecting seat 502 to be engaged with the striking element 501 and the plunger 202 to achieve stable connection. Indeed, in other embodiments, the striking element 501 and the plunger 202 may be connected to the connecting seat 502 by welding or the like, and a stable connection may also be achieved, which is not specifically limited herein, depending on the actual situation. Among them, the striking member 501 is a striker.

Referring to fig. 27 and 29, the connecting seat 502 has an initial position a disposed away from the cylinder 201 and an energy storage position B disposed close to the cylinder 201, and the driving mechanism 60 drives the connecting seat 502 to move from the initial position a to the energy storage position B, so that the plunger 202 moves from the first port 2011 to the second port 2012, and further compresses the gas to achieve the effect of energy storage. It should be noted that after the driving mechanism 60 drives the connecting seat 502 to the energy storage position B, the driving mechanism 60 continues to move to disengage from the connecting seat 502, so that the plunger 202 moves toward the first port 2011 rapidly under the action of the compressed gas, and further drives the striking member 501 to move toward the direction away from the first port 2011, thereby implementing the striking action.

Referring to fig. 23, in order to prevent the connecting socket 502 from turning over under the action of the driving mechanism 60, thereby improving the stability of the movement of the connecting socket 502, the connecting socket 502 is provided with a mating surface 5021 abutting against the driving mechanism 60. The adapting surface 5021 is an arc surface, and the center of the circle corresponding to the arc surface is located on the center line of the striking piece 501. The purpose of this is to: the connecting seat 502 is always stressed towards the center of the plunger 202 when being subjected to impact force, so that the plunger 202 is prevented from generating lateral force, the phenomenon that the plunger 202 overturns is avoided, and the stability of the energy storage mechanism 20 is improved. Wherein the arc-shaped surface is arranged towards a direction away from the first port 2011.

Specifically, the connection seat 502 includes a body portion 5022 fixedly connected to the striking member 501 and an abutting portion 5023 connected to the body portion 5022, and the mounting hole is disposed on the body portion 5022. It is noted that the mounting holes on both sides are not arranged through. That is, the mounting holes on both sides are not communicated to prevent the striking piece 501 and the plunger 202 from being connected, and the connecting seat 502 can move along the circumferential direction of the striking piece 501 and the plunger 202 through the mounting holes, thereby improving the overall performance of the nail gun 100.

Referring to fig. 24, the abutting portion 5023 has a first end 5024 and a second end 5025 opposite to each other, and at least a portion of the driving mechanism 60 moves between the first end 5024 and the second end 5025. Please refer to fig. 27 to 29, which are combined to drive the connecting seat 502 to move from the initial position a to the energy storing position B. Specifically, when at least a portion of the driving mechanism 60 moves from the first end 5024 to the second end 5025, the connecting seat 502 moves from the initial position a toward the energy storage position B by a distance that is half of the distance between the initial position a and the energy storage position B; when at least a portion of the drive mechanism 60 is moved from the second end 5025 to the first end 5024, at least a portion of the drive mechanism 60 continues to move toward the charged position B until the charged position B is reached, which is also half the distance between the initial position a and the charged position B, thereby allowing the gas within the cylinder 201 to be compressed to its full extent. The purpose of this is to: make things convenient for actuating mechanism 60 and butt 5023 butt, simultaneously, can also reduce the length of butt 5023, and then reduce the casing 10 width.

Referring to fig. 18 to fig. 20, the motor 30 is connected to the driving mechanism 60, so that the driving mechanism 60 moves, and further the driving mechanism 60 drives the connecting seat 502 to move to drive the striking member 501 to move linearly. The nailer 100 also includes a reduction gearbox 40 connected to the motor 30, the reduction gearbox 40 being configured to adjust the high speed of the motor 30 to a set speed. The motor 30 is located below the reduction gear box 40 in the height direction of the nail gun 100. The reduction gearbox 40 has an output shaft which is connected to a drive mechanism 60.

As mentioned above, since the connecting seat 502 drives the plunger 202 to move linearly under the action of the driving mechanism 60, correspondingly, the connecting seat 502 also moves linearly. The linear movement is along the length of the housing 10 and thus does not affect the width of the housing 10. Therefore, the volume, weight and motion trajectory of the driving mechanism 60 play a critical role in the size of the housing 10. When the movement locus of the driving mechanism 60 in the length direction of the casing 10 is kept constant, the moving range of the driving mechanism 60 in the width direction of the casing 10 is larger, resulting in the larger width of the casing 10. The length direction of the casing 10 is a first linear direction in which the connecting seat 502 is driven by the driving mechanism 60 to perform a linear reciprocating motion, and the width direction of the casing 10 is a direction orthogonal to the first linear direction, i.e., a second linear direction.

The driving mechanism 60 includes a driving member 601 selectively coupled to or separated from the coupling socket 502. When the connecting seat 502 is in the initial position a, the driving member 601 can be coupled with the connecting seat 502 and drive the connecting seat 502 to move to the energy storage position B; when the connecting seat 502 moves to (i.e., reaches) the energy storage position B, or when the connecting seat 502 crosses the energy storage position B, the driving member 601 can be separated from the connecting seat 502, and at this time, the plunger 202 drives the connecting seat 502 to move toward the fastener under the action of the compressed gas, so as to strike the fastener into the target object.

As described above, the driving member 601 and the abutting portion 5023 can be selectively coupled or separated. When the driving member 601 drives the connecting socket 502 to move from the initial position a to the energy storage position B, the driving member 601 first moves from the first end 5024 to the second end 5025 of the abutting portion 5023 of the connecting socket 502, and then moves from the second end 5025 to the first end 5024. The driving member 601 continues to move and is separated from the first end 5024 and the connecting seat 502 moves from the energy storage position B to the initial position a. That is, when the driving member 601 is coupled to the connecting socket 502, the driving member reciprocates on the abutting portion 5023 of the connecting socket 502.

In the process that the connecting seat 502 moves from the initial position a to the energy storage position B, the driving member 601 has a first moving distance in the first linear direction and a second moving distance in the second linear direction, and the second moving distance is smaller than the first moving distance. As mentioned above, the first moving distance is a distance between the initial position a and the energy storage position B, and the second moving distance is a distance formed by the driving member 601 and the abutting portion 5023 performing a reciprocating motion thereon. By making the second moving distance smaller than the first moving distance, so that the moving distance of the driving member 601 in the second linear direction (i.e. the width of the housing 10) is small, the purpose of reducing the width of the housing 10 can be achieved, and then the overall size of the nail gun 100 is reduced, thereby ensuring the accessibility and the man-machine coordination of the nail gun 100.

In order to guide the movement direction of the driving mechanism 60, so that the driving mechanism 60 smoothly drives the connecting seat 502 to drive the plunger 202, and prevent the connecting seat 502 from being shifted or turned over under the driving of the driving mechanism 60, the driving mechanism 60 further comprises a guide assembly 602. The guide assembly 602 is disposed in the housing to guide a moving direction of the driving member 601, such that the driving member 601 moves along the guide assembly 602 and then drives the connecting seat 502 to move from the initial position a to the energy storing position B.

The guide assembly 602 in this application includes a guide part 6021 coupled to the driving member 601 and a guide part 6022 fixedly disposed with respect to the housing 10, the guide part 6021 and the guide part 6022 cooperating to provide a guide for the movement of the driving member 601. The driving member 601 has a first predetermined displacement in a first linear direction of the connecting seat 502 and a second predetermined displacement in a second linear direction. To ensure that the width of the housing 10 is not increased, the second predetermined displacement is less than the first predetermined displacement. The first preset displacement is the distance between the initial position a and the energy storage position B. Meanwhile, the second predetermined displacement is smaller than the minimum width of the casing 10 enclosed outside the driving mechanism 60. The purpose of this is to: so that the housing 10 can be disposed along its minimum width without the entire volume and movement distance of the driving mechanism 60 affecting the width of the housing 10, thereby achieving the purpose of reducing the width of the housing 10 thereof, and consequently ensuring the accessibility and the ergonomics of the nail gun 100.

Referring to fig. 38 and 39, one of the guide part 6021 and the guide part 6022 may be configured as a guide groove 6022, and the other of the guide part 6021 and the guide part 6022 is configured as a guide rod that mates with the guide groove 6022, and the guide rod is slidably engaged with the guide groove 6022. In the present embodiment, the guide portion 6022 is provided as the guide groove 6022, further ensuring that the width of the housing case 10 is not increased. The guide groove 6022 has an elliptical shape, and the elliptical guide groove 6022 has a major axis a corresponding to a first linear direction of the connector base 502 and a minor axis b corresponding to a second linear direction orthogonal to the first linear direction. Wherein the short diameter b is provided along the width direction of the housing 10, thereby limiting the moving range of the driving mechanism 60 in the width direction of the housing 10.

Wherein the major diameter a is greater than or equal to the distance between the initial position a and the energy storage position B. Such that the drive mechanism 60, when moved along the major axis a, can drive the connecting socket 502 to drive the plunger 202 to compress the gas in place.

In one embodiment, the driving member 601 includes a body 6011 and a driving rod 6012 connected to the body 6011. The driving rod 6012 and the connecting seat 502 can be selectively coupled or separated, and the guide part 6021 is disposed on both sides of the body 6011 opposite to the driving rod 6012. In this embodiment, the guide 6021 is disposed near the end of the driving member 601, so as to reduce the overall length of the driving member 601, thereby controlling the driving member 601 to rotate in the width direction of the housing 10, and the overall width of the driving member 601 is also smaller than the minimum width of the housing 10 enclosed outside the driving mechanism 60, thereby ensuring the minimization of the width of the housing 10. Further, since the guide groove 6022 has an elliptical shape, the diameter of the elliptical guide groove 6022 changes. During the process that the driving member 601 slides along the guide groove 6022 through the guide part 6021, the two guide parts 6021 limit the movement of the driving member 601 on the guide groove 6022, so only one guide part 6021 is needed.

The driving rod 6012 abuts against the abutting portion 5023 of the connecting socket 502, drives the connecting socket 502 to move from the initial position a to the energy storage position B in a first time period, and disengages from the abutting portion 5023 in a second time period, so that the striking member 501 is struck. The first time period is the time when the connection seat 502 moves from the initial position a to the energy storage position B, and the second time period is the time when the connection seat 502 moves from the energy storage position B to the initial position a after the abutting portion 5023 is disengaged from the driving rod 6012.

Referring to fig. 21 and 38 to 40, similarly, the driving rod 6012 is disposed at an end of the driving member 601 to reduce the overall length of the driving member 601, so that when the driving member 601 is controlled to rotate in the width direction of the housing 10, the width of the driving member 601 is smaller than the minimum width of the housing 10 surrounding the driving mechanism 60, thereby ensuring the minimum width of the housing 10. In order to facilitate the movement of the driving rod 6012, the driving rod 6012 has an abutting surface 6013, and the abutting surface 6013 is also an arc surface.

Adaptively, the friction between the driving rod 6012 and the abutment 5023 may be enhanced according to practical requirements, for example, for stability between the driving rod 6012 and the abutment 5023, while the friction does not affect the movement of the driving rod 6012 on the abutment 5023. The increase of the friction force can be achieved by adding a bump or a groove on the abutting surface 6013 of the driving rod 6012, which is not specifically limited herein and is determined according to the actual situation.

In order to ensure that the motor 30 does not affect the width of the casing 10 when the driving body 6011 moves, so as to increase the width of the casing 10, the driving mechanism 60 further includes a limiting member 603 for limiting the moving range of the driving member 601.

At least one limiting member 603 is provided, and at least one limiting member 603 is provided at one side of the driving member 601. Referring to fig. 3 to 5, the output shaft of the reduction box 40 is connected to the limiting member 603 to drive the limiting member 603 to rotate, and then drive the driving member 601 to rotate.

Wherein, the limiting part 603 is provided with a protrusion 6031, the protrusion 6031 is arranged towards the direction of the reduction gearbox 40, and then is butted with the output shaft of the reduction gearbox 40, so as to drive the limiting part 603 to move under the driving of the motor 30. The movement of the position-limiting member 603 drives the driving member 601 to move, thereby driving the connecting base 502.

The limiting member 603 and the driving member 601 are clamped to realize that the driving member 601 moves along with the limiting member 603. Specifically, one of the driving element 601 and the limiting element 603 is provided with a limiting groove 6032, the other of the driving element 601 and the limiting element 603 is provided with a limiting block 6014 matched with the limiting groove 6032, and the diameter of the limiting groove 6032 is greater than that of the limiting block 6014. The purpose of this is to: the guide groove 6022 is elliptical, the driving member 601 is displaced in the horizontal direction during the movement along the guide groove 6022, and when the driving member 601 and the limiting member 603 move from the major diameter a of the guide groove 6022 to the minor diameter b of the guide groove 6022, the limiting member 6014 can move in the limiting groove 6032, and thus, the movement of the driving member 601 is not affected. In this embodiment, the driving member 601 is provided with a limiting block 6014, and the limiting block 603 is provided with a limiting groove 6032. The specific positions of the limiting block 6014 and the limiting groove 6032 are not limited, and the purpose of clamping is achieved.

The position-limiting element 603 on at least one side of the driving element 601 may be disposed below the driving element 601 or disposed above the driving element 601. When the limiting member 603 is located below the driving member 601, a connecting block connected to the driving member 601 is further required to be disposed on the upper surface of the limiting member 603, so that the structural complexity of the limiting member 603 is increased, and the overall weight of the driving mechanism 60 is also increased. Therefore, in the present embodiment, the limiting member 603 is disposed above the driving member 601.

Since the boss 6031 abuts on the output shaft of the reduction gear box 40, the boss 6031 is disposed downward in the height direction of the nail gun 100. Therefore, the driving member 601 defines a first notch 6015 for receiving the protrusion 6031, and a diameter of the first notch 6015 is larger than a diameter of the protrusion 6031, so that the driving member 601 can move in a horizontal direction relative to the position-limiting member 603. The purpose of this is to: when the driving member 601 moves from one end of the major diameter a to one end of the minor diameter b of the elliptical guide groove 6022, the driving member 601 moves in the horizontal direction due to the cooperation of the guide member 6021 with the guide groove 6022, and the first notch 6015 is configured to allow the driving member 601 to move in the horizontal direction.

In order to better realize the fit between the guide part 6021 and the guide groove 6022, in the embodiment, two limiting parts 603 are provided, and the two limiting parts 603 are respectively provided on two sides of the driving part 601. At this time, a second notch 6033 for accommodating the protrusion 6031 is disposed on the limiting member 603 under the driving member 601, and the diameter of the second notch 6033 is larger than that of the protrusion 6031, for the same reason as the first notch 6015, which is not described herein again.

In addition, in order to enable the driving member 601 to smoothly rotate when moving to the width direction of the housing 10, an accommodating groove 6034 may be formed in one of the driving member 601 and the limiting member 603. At this time, the driving mechanism 60 further includes a ball 604, and the ball 604 is at least partially protruded out of the receiving groove 6034. By providing the ball 604, the driving member 601 can smoothly slide on the stopper 603, so that the stability of the entire nail gun 100 can be improved without causing any drag. In the present embodiment, the accommodating groove 6034 is disposed on the position-limiting member 603.

In another embodiment, the driving member 601 can be a telescopic rod, and the limiting member 603 can be a crank. One end of the crank is connected with an output shaft of the reduction gearbox 40, and the other end of the crank is fixedly connected with the telescopic rod. At this time, the guide 6021 is disposed on the telescopic rod. The crank is rotated by the reduction gearbox 40 and the motor 30, and the guide 6021 abuts against the abutment 5023 of the connecting base 502. When the crank moves from one end of the major diameter a to one end of the minor diameter b of the elliptical guide groove 6022, the telescopic rod is converted from the extended state to the compressed state. When the crank moves from one end of the rectangular diameter B to the other end of the major diameter a of the elliptical guide groove 6022, the telescopic rod is restored from the compressed state to the extended state, and then the connecting seat 502 is driven to move the connecting seat 502 from the initial position a to the energy storage position B.

Referring again to fig. 18, the nail gun 100 is generally configured with the nail magazine 70, with the nail magazine 70 disposed on a side of the main housing away from the grip housing. The nail magazine 70 includes a first magazine fixedly connected to the main housing and a second magazine detachably connected to the first magazine, and the purpose of this is that: when there are few or no nails in the nail magazine 70, the second magazine can be removed to replace the nails quickly and conveniently. Indeed, in other embodiments, the magazine 70 may be removably attached to the main housing in its entirety, and the magazine 70 may be replaced in its entirety when the nails in the magazine 70 are exhausted.

Since the power of the entire nail gun 100 is supplied by electric power, the nail gun 100 is generally provided with an electric power mechanism. The power mechanism may be a plug with a connecting cord, or a battery pack.

When the electric power mechanism is a plug having a connecting wire, it is required to be fixedly connected to the nail gun 100 so as to limit the moving range of the nail gun 100 when in use, but the electric power is not limited because the time of use of the nail gun 100 is not limited.

When the electric mechanism is a battery pack, the range of movement of the nail gun 100 when in use is not limited, but the time of use of the nail gun 100 is limited. Therefore, the battery pack can be detachably connected with the housing, and when the battery pack is not charged when being connected with the nail gun 100, the battery pack can be detached, so that the fully charged battery pack can be replaced, the nail gun 100 can be continuously used, and the nail gun is convenient and quick.

In summary, the following steps: by providing the driving member 601 and the guiding member 602 which can be selectively coupled or separated with or from the connecting base 502, the guiding member 602 includes a guiding part 6021 connected with the driving member 601 and a guiding part 6022 fixedly arranged with respect to the housing 10, and the guiding part 6022 and the guiding part 6021 cooperate with each other to provide guidance for the movement of the driving member 601, so that the driving member 601 moves in a predetermined direction without deviation, and the overall movement is more stable; moreover, the guide assembly 602 and the driving member 601 have simpler structures, so that the effect of reducing the overall volume and weight of the nail gun 100 is achieved; meanwhile, the preset displacement of the guide part 6021 in the first linear direction of the connecting seat 502 is larger than the preset displacement of the guide part 6021 in the second linear direction, so that the width of the casing 10 in the second linear direction is reduced, and the accessibility and the man-machine coordination of the nail gun 100 are further ensured; in the process that the driving member 601 drives the connecting seat 502 to move from the initial position a to the energy storage position B, the moving distance of the driving member 601 in the first linear direction is set to be smaller than the moving distance of the driving member 601 in the second linear direction, so that the width of the housing 10 is further reduced, and the accessibility and the man-machine coordination of the nail gun 100 are ensured again. The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model.
