Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1 and 2, the rotary head of the embodiment includes a mounting sleeve 1, a rotary actuator 3, a key cylinder mounting body 2, a key cylinder 11 and a sealing member 5. Wherein, the mounting sleeve 1 is internally provided with a mounting hole. The rotation executing component 3 is fixed outside the mounting sleeve 1. The key cylinder mounting body 2 is fixed in the mounting hole, and a moving passage 201 is formed, and the moving passage 201 has an extension along a rotation circumferential direction of the rotation actuator 3. The lock core 11 is movably disposed in the moving channel 201, and a portion of the lock core is exposed out of the moving channel 201. The lock cylinder 11 is locked when the moving channel 201 moves forward; the lock cylinder 11 is unlocked when the moving channel 201 moves reversely; the sealing member 5 is at least partially fixed in the mounting hole and is located at the open end of the mounting hole, in connection with fig. 1, i.e. the sealing member 5 is located at the lower side of the cylinder mounting body 2.
Wherein, the above-mentioned "the moving channel 201 has an extension along the rotation circumferential direction of the rotation executing part 3", that is, the extending direction of the moving channel 201 has a tangential component along the rotation circumferential direction of the stirring executing part 3 ", means that: when the rotary head and the driving shaft 4 are installed and the driving shaft 4 rotates along the set direction, the lock cylinder 11 can be driven to move forward along the moving channel 201 and be locked. That is, the moving passage 201 does not extend in a direction having only a component in the axial direction of the mounting hole or the radial direction of the rotation circumference, but has a component in the tangential direction of the rotation circumference. The "rotation circle" refers to an arbitrary circle having the central axis of the drive shaft 4 as the center axis.
In addition, references to "forward" and "reverse" in this document are only relative concepts. For example, the forward direction may be clockwise or counterclockwise, the forward direction may be leftward or rightward, or the forward or backward direction may be forward. When the direction of the forward representation is determined, the reverse representation is the direction opposite to the forward representation.
The mounting sleeve 1, the rotary actuating component 3, the lock cylinder mounting body 2, the lock cylinder 11 and the sealing piece 5 of the rotary head are integrated. When mounting, it is only necessary to mount the rotary head directly on the drive shaft 4. Along with the rotation of drive shaft 4, drive shaft 4 can drive lock core 11 forward motion for lock core 11 locking is in order to realize the locking between rotating head and the drive shaft 4, prevents that rotatory in-process rotating head from droing from drive shaft 4. After the rotation process is finished, the lock cylinder 11 is unlocked by reverse movement under the action of external force, and then the rotating head and the driving shaft 4 can be easily separated at the moment, so that the rotating head can be quickly detached. Therefore, the rotating head ensures the use safety of products while ensuring the quick disassembly and assembly, and prevents equipment from being damaged and using accidents from happening. In addition, through the setting of sealing member 5, can prevent outside impurity to get into in the installation cover 1, avoid impurity to influence the locking effect of lock core 11 to guarantee the inside cleanliness factor of rotating head.
Because the installation sleeve 1, the rotary execution part 3, the lock cylinder installation body 2, the lock cylinder 11 and the sealing piece 5 are taken as a whole when being disassembled and assembled, namely, the rotary head has no other redundant parts, the condition that one or more parts are forgotten in the disassembling and assembling process of the rotary head is avoided. The rotating head is fast to disassemble and assemble, a disassembling tool is not needed, and a user does not need to check whether the rotating head is disassembled and assembled in place after the rotating head is disassembled and assembled; and can be repeatedly disassembled and assembled. To the container of installing this kind of rotating head and even food processor, its dismantlement is convenient, in order to realize fully rinsing, need not to stretch out inside the hand gets into the container, consequently can avoid user's hand injured in the cleaning process, and safety in utilization promotes greatly.
The expression that the lock cylinder mounting body 2 is fixed in the mounting hole means that the lock cylinder mounting body 2 is tightly fixed in the mounting hole, and then the lock cylinder mounting body 2 cannot slide from the mounting sleeve 1 and cannot move in the mounting hole of the mounting sleeve 1.
Likewise, "the seal 5 is at least partially fixed in the mounting hole" means: the seal 5 cannot slip off the mounting sleeve 1 and play cannot occur in the mounting hole of the mounting sleeve 1.
In one embodiment, in order to fixedly mount both the key cylinder mounting body 2 and the sealing member 5 to the mounting sleeve 1, interference fits are used between the outer surface of the key cylinder mounting body 2 and the mounting hole, and between the outer surface of the sealing member 5 and the mounting hole.
In another embodiment, in order to fixedly mount both the key cylinder mounting body 2 and the sealing member 5 with the mounting sleeve 1, the mounting sleeve 1 is made of an elastic material, and when the key cylinder mounting body 2 and the sealing member 5 are mounted in the mounting hole, the mounting sleeve 1 is expanded to fasten the key cylinder mounting body 2 and the sealing member 5 in the mounting hole.
Of course, the lock cylinder mounting body 2 and the sealing member 5 can be fixed in the mounting hole of the mounting sleeve 1 by any fixing connection method disclosed in the prior art.
Referring to fig. 3 and 4, in one embodiment, the moving channel 201 includes a transition surface 204, the transition surface 204 includes a locking end and an unlocking end, and the distance between the transition surface 204 and the central axis of the mounting hole gradually increases from the locking end to the unlocking end. Since the transition surface 204 includes a locking end and an unlocking end, it is known that the transition surface 204 actually functions to cooperate with the lock cylinder 11 to achieve locking or unlocking. It follows that the transition surface 204 is formed in the wall surface of the displacement channel facing the central axis of the mounting hole.
During installation, the driving shaft 4 drives the lock cylinder 11 to move in a forward direction, so that the lock cylinder 11 moves to the locking end. After the end of the rotation process, the lock cylinder 11 is moved back in the opposite direction by the external force to the unlocking end or to the vicinity of the unlocking end.
The number of displacement channels 201, transition surfaces 204 and lock cylinders 11 is typically one-to-one. Of course, no special requirements are made on the distribution and specific number of the moving channels 201, the transition surfaces 204 and the lock cylinders 11 in the mounting holes, and it is only required that the lock cylinder mounting body 2 at least comprises one moving channel 201, and then at least one lock cylinder 11 can lock the driving shaft 4 when the driving shaft 4 rotates. Also, the shape of the key cylinder mounting body 2 is not particularly required, as long as the moving passage 201 can be formed in the key cylinder mounting body 2.
Here, a plurality of moving channels 201 may be formed in one key cylinder mounting body 2, or only one moving channel 201 may be formed in one key cylinder mounting body 2. When only one moving channel 201 is formed on one lock cylinder mounting body 2 and the number of the moving channels 201 is multiple, a plurality of lock cylinder mounting bodies 2 are distributed in the mounting hole.
In one embodiment, the key cylinder mounting body 2 is provided with a reset device 12, and the reset device 12 maintains the initial position of the key cylinder 11 at the unlocking end. Through the setting of reset part 12 for under the rotating head initial condition, lock core 11 is located the unblock end, and then makes things convenient for drive shaft 4 to get into the mounting hole. If the reset part 12 is not provided, the lock cylinder 11 may be located at the locking end at the beginning, and the rotary head is mounted on the driving shaft 4, so that the driving shaft 4 can enter the corresponding position of the mounting hole, an external force needs to be additionally applied to the lock cylinder 11 to move the lock cylinder 11 to the unlocking end.
Wherein, restoring element 12 may be a magnetic element or an elastic element. When restoring member 12 is a magnetic member: if the magnetic component and the lock cylinder 11 repel each other, the magnetic component is arranged at or near the locking end; when the magnetic member and the locking member are attracted to each other, the magnetic member is disposed at or near the unlocking end.
When the restoring member 12 is an elastic member, a first end of the elastic member is fixed to the key cylinder mounting body 2, a second end is connected to the key cylinder 11, and the key cylinder 11 is located at the unlocking end when the elastic member is in a free state. The term "the elastic member is in a free state" refers to a state in which the elastic member is not subjected to an external force, and the gravity of the elastic member can be ignored. Wherein, the reset piece can be a reset spring.
In one embodiment, referring to fig. 5-7, the travel path includes a circumferential surface, and the lock cylinder 11 is rotationally locked in a forward direction and rotationally unlocked in a reverse direction. Here, the lock cylinder 11 is rotated in the forward direction, which corresponds to the above-mentioned forward movement of the lock cylinder 11; the lock cylinder 11 is rotated in the reverse direction, i.e. in the reverse direction in correspondence with the above-mentioned lock cylinder 11. And the circumferential surface of the moving passage is coaxial with the drive shaft 4 to be assembled.
In one embodiment, the lock cylinder mounting body 2 includes an outer race 202 and a cage, and the lock cylinder 11 includes rolling bodies. The retainer is annular and is adapted to the outer ring 202, and is coaxially disposed in the outer ring 202, and a plurality of moving channels 201 are formed between the retainer and the outer ring 202. The rolling bodies are provided in one-to-one correspondence with the moving passages 201. When the rolling bodies move along the moving channel 201, the rolling body portions are exposed to the moving channel 201. When the driving shaft 4 is inserted into the mounting hole, the rolling bodies exposed to the moving passage 201 contact the driving shaft 4.
It is worth mentioning that when the lock cylinder mounting body 2 includes the outer race 202 and the retainer, and the lock cylinder 11 includes the rolling bodies, the lock cylinder mounting body 2 and the lock cylinder 11 can be regarded as a one-way bearing at this time. That is, a one-way bearing is provided inside the mounting sleeve 1. When the drive shaft 4 enters the mounting hole and enters the fitting hole of the one-way bearing, the rolling elements of the one-way bearing are in the unlocked state at this time. When the driving shaft 4 rotates towards the set direction, circumferential locking between the driving shaft 4 and the one-way bearing can be realized, and then the driving shaft 4 can drive the one-way bearing to rotate. In this case, the one-way bearing is equivalent to a one-way lock, and is locked with the drive shaft 4 only when the drive shaft 4 rotates in the set direction; instead, the one-way bearing is unlocked from the drive shaft 4.
When the drive shaft 4 drives the rotating head to rotate, the faster the rotating speed, the larger the centripetal force that the rolling element received, and then the locking force that the drive shaft 4 received is bigger, and it is more reliable to guarantee the rotating head installation. When the rotation speed of the driving shaft 4 is relatively low, although the locking force of the driving shaft 4 to the rotary head is relatively small, the locking force can also ensure the installation reliability of the rotary head due to the slow rotation speed of the driving shaft 4.
After the unidirectional bearing is assembled, the rolling bodies are exposed in the assembly holes of the unidirectional bearing. When the drive shaft 4 is inserted directly into the adapter bore, the rolling bodies come into contact with the side faces of the drive shaft 4, ensuring that there is no clearance between the drive shaft 4 and the assembly bore. Of course, a protective sleeve or other protective member may be provided around the drive shaft 4, and in this case, when the drive shaft 4 is inserted into the mounting hole, the rolling elements and the drive shaft 4 may not be in direct contact with each other. However, no matter what part is sleeved outside the driving shaft 4, the driving shaft 4 rotates along the set direction, the rolling bodies can be driven to move in the forward direction and be locked, the rolling bodies are tightly held on the periphery of the driving shaft 4, one-way locking of the one-way bearing is achieved, and therefore the rotating head is driven to rotate synchronously. When the drive shaft 4 drives the rolling bodies to move reversely, the one-way bearing is in an unlocking state, and the rotating head cannot rotate along with the drive shaft 4 at the moment.
Taking the cylinder mounting body formed with the transition surface 204 as an example, when the driving shaft 4 drives the lock cylinder 11 to lock in the forward direction (i.e. rolling towards the lock end of the transition surface 204), the rolling bodies are held tightly around the outer circumference of the driving shaft 4. When the drive shaft 4 drives the rolling bodies to move reversely (i.e. roll towards the unlocking end of the transition surface 204) to unlock, the one-way bearing is in an unlocked state, and the rotating head cannot rotate along with the drive shaft 4.
The rolling bodies can be needle rollers, rolling shafts, rolling balls or wedge-shaped blocks and the like, and the types of the corresponding rolling bodies are selected according to the use occasions.
In fig. 5 to 7, the rolling elements are wedge shaped blocks. And, the specific structural form of the wedge block is not limited by the examples herein, for example, the wedge block may also be in the structural form in fig. 8 and 9.
Besides certain strength, the material of the retainer is preferably good in heat conductivity, small in friction factor, good in wear resistance, strong in impact toughness and close to a rolling body in linear expansion coefficient. The material of the retainer can be selected according to the specific application. For example, the cage is a low carbon steel/stainless steel cage, a bakelite/plastic cage, a brass/bronze/aluminum alloy cage, or the like.
When the reset device 12 is an elastic member and the key cylinder mounting body 2 includes an outer ring 202 and a holder, the key cylinder mounting body 2 further includes a mounting bracket 203 for facilitating the mounting of the elastic member, and the mounting bracket 203 is fixed on the holder and/or the outer ring 202. The mounting bracket 203 may be integrally formed with the outer ring 202 or may be integrally formed with the cage. Of course, the mounting bracket 203 may also be a separate component, and may be connected with the outer ring 202 and/or the holder by other connection methods such as plugging, clipping, and adhering. Moreover, the mounting bracket 203 may be in the form of a sheet, a block, a rod, etc., and the specific shape is not required as long as the elastic member can be conveniently mounted.
In fig. 3 and 4, the mounting bracket 203 is arranged near the unlocking end of the transition surface 204 and is connected with one end of the elastic member, and the initial position of the rolling body is ensured at the unlocking end by the elasticity of the elastic member.
It should be noted that, in order to facilitate the movement of the lock cylinder 11, the transition surface 204 is generally a smooth transition surface, and the "smooth" in the "smooth transition surface" is a definition of the shape of the transition surface 204, but not a definition of the friction coefficient of the transition surface 204. And the smooth transition surface can be a plane or a cambered surface. Furthermore, when the lock cylinder 11 is a rolling member rather than a sliding member, the friction coefficient of the smooth transition surface should not be too low; conversely, when the lock cylinder 11 is a sliding member rather than a rolling member, the friction coefficient of the smooth transition surface should not be too high.
It should be noted that the transition surface 204 may also be directly formed on the inner wall of the mounting hole, in this case, the key cylinder mounting body 2 may be integrally formed with the mounting sleeve 1, and further, a moving passage 201 of the key cylinder 11 is formed inside the mounting sleeve 1.
In order to ensure that the drive shaft 4 and the mounting hole are coaxial, the number of the lock cylinders 11 is preferably plural and evenly distributed between the drive shaft 4 and the mounting hole. Under this kind of circumstances, drive shaft 4 atress is balanced, can guarantee the stability in drive shaft 4 and the rotating head course of working. Of course, the distribution of the key cylinders 11 is determined by the key cylinder mounting body 2 formed with the moving passage 201.
Wherein the cross section of the mounting hole and the cross section of the drive shaft 4 may be of any shape. When the cross section of the driving shaft 4 is circular, and the lock cylinder mounting body 2 and the lock cylinder 11 adopt the structural form of the one-way bearing, 360-degree omnibearing assembly can be realized by the driving shaft 4 and the rotating head at the moment, the mounting angle does not need to be adjusted in the assembly process, and the rotating head is convenient to mount.
The sealing element 5 can be only partially fixed in the mounting hole, while the remaining part is exposed outside the mounting hole, in which case there is no necessary relationship between the axial dimensions of the mounting hole, the cylinder mounting body 2 and the sealing element 5, and the choice of the sealing element 5 is flexible.
In one embodiment, the sealing member 5 is a sealing ring, a through hole for the driving shaft 4 to pass through is formed on the sealing ring, and other components are not sleeved outside the driving shaft 4. Further, the drive shaft 4 passes through the fitting hole into the mounting hole and contacts the lock cylinder 11 in the moving passage 201, and the open end of the mounting hole is sealed by the packing. The sealing ring is simple in structure, and can well prevent solid particles or liquid from entering the mounting hole. Especially when the rotating head is used for products such as soybean milk machine, juice extractor, broken wall machine, can produce more solid particle and liquid material in food course of working, then the setting of sealing washer can be better guaranteed that the mounting hole is inside clean, avoids the impurity to exert an influence on 11 locking effects of lock core to be convenient for wash of product.
Of course, instead of being in the form of a sealing ring, the sealing element 5 may also be in the form of an inflatable sealing plug, or may also be in the form of a plurality of split sealing blocks, or any of the sealing elements 5 known in the art.
It is worth mentioning that the mounting hole can be closed at one end and open at the other end, or both ends can be open. When the mounting hole both ends are all open-ended, for better preventing that the mounting hole is inside to receive the pollution, all set up sealing member 5 at two open ends of mounting hole.
When the sealing member 5 is completely located in the mounting hole, the rotary head further includes a first magnetic member 10, the first magnetic member 10 is fixed in the mounting hole, and along the axial direction of the mounting hole, the lock cylinder mounting body 2, the sealing member 5 and the first magnetic member 10 are sequentially arranged. I.e. the first magnetic means 10 is located on the lower side of the sealing member 5 in fig. 1, and the sealing member 5 is located on the lower side of the cylinder mounting body 2. Since the first magnetic member 10 is disposed on the rotary head, and when the rotary head is installed, the first magnetic member 10 is closest to the driving shaft 4, the rotary head can be fastened on the driving shaft 4 by the first magnetic member 10 and the attraction between the corresponding magnetic members on the driving shaft 4, so as to prevent the rotary head from sliding off the driving shaft 4 under a specific working condition.
The first magnetic member 10 refers to an object that can react to a magnetic field in some way, and does not need to be able to generate a magnetic field by itself. The first magnetic member 10 can be made of any magnetic material, such as a magnet, mild steel, etc.; of course, the first magnetic member may be an energized coil. Also, the second magnetic member 8 mentioned later may be made of any magnetic material or may be in the form of an energized coil, and the specific form is not limited as long as the first magnetic member 10 and the second magnetic member 8 can generate magnetic attraction force.
In one embodiment, the first magnetic member 10 is a ring-shaped magnetic plate, and a through hole for the driving shaft 4 to pass through is formed on the ring-shaped magnetic plate. The first magnetic member 10 with this structure can be sufficiently exposed to the magnetic field, so as to ensure the magnetic attraction of the magnetic member to the rotary head.
When one end of the mounting hole is closed and the other end is opened, the rotating head further comprises a mounting shaft 6, the mounting shaft 6 is coaxial with the mounting sleeve 1, and a first limit step 13 is formed between the mounting shaft 6 and the mounting sleeve 1. It is clear that the end of the mounting sleeve 1 corresponding to the opening of the mounting hole is required for assembly with the drive shaft 4, and therefore the mounting shaft 6 cannot be fixed to this end. Thus, the mounting shaft 6 is necessarily fixed to the mounting sleeve 1 at the closed end corresponding to the mounting hole, and the first limit step 13 is formed between the mounting shaft 6 and the end surface of the mounting sleeve at the closed end.
Wherein, the mounting shaft 6 and the mounting sleeve 1 can be integrally formed.
Referring to fig. 2 and 11, the rotation executing member 3 is fitted around the mounting shaft 6 and abuts against the first limit step 13. By the arrangement of the mounting shaft 6, and the formation of the first limit step 13, the mounting position of the rotation actuator 3 can be determined.
When the mounting shaft 6 is provided, the rotation actuator 3 is not directly fixed to the mounting sleeve 1, but is indirectly fixed to the outside of the mounting sleeve 1 via the mounting shaft 6. In addition, the present invention is intended to cover both the case of directly fixing the rotation actuator 3 to the outside of the mounting sleeve 1 and the case of indirectly fixing the rotation actuator to the outside of the mounting sleeve 1.
Wherein the outside of the mounting sleeve 1 corresponds to the inside of the mounting sleeve 1, and the mounting holes belong to the inside of the mounting sleeve 1.
In order to ensure that the mounting sleeve 1 rotates and the mounting shaft 6 drives the rotation executing component 3 to rotate, the matching parts of the mounting shaft 6 and the rotation executing component 3 are all provided with non-rotating parts so as to avoid the rotation of the rotation executing component 3 relative to the mounting shaft 6.
For example, the cross sections of the fitting parts of the mounting shaft 6 and the rotary actuator 3 may be polygonal, elliptical, irregular, etc.
Of course, when the fitting portions of the mounting shaft 6 and the rotation executing component 3 are all provided as rotating portions, the circumferential locking of the mounting shaft 6 and the rotation executing component 3 can also be realized by additionally using a locking member or a fastening connection manner, so as to prevent the rotation executing component 3 from rotating relative to the mounting shaft 6.
In order to prevent the axial play of the rotary actuator 3 along the mounting shaft 6, a first stop 7 may be additionally provided. Specifically, the first stopper 7 is fixed on the mounting shaft 6 and abuts the rotation executing member 3 to the first limit step 13.
The first stopper 7 may be an elastic stop collar having a certain elasticity. In the installation process, the rotation executing component 3 can be firstly arranged at the first limit step 13, and then the elastic limit sleeve is fixed on the installation shaft 6, so that the end part of the elastic limit sleeve contacts the rotation executing component 3 to prevent the rotation executing component 3 from axially moving along the installation shaft 6. Or, the rotation executing component 3 and the elastic limiting sleeve may be mounted on the mounting shaft 6 first, and then the elastic limiting sleeve is moved toward the first limiting step 13 until the rotation executing component 3 abuts against the first limiting step 13 and the elastic limiting sleeve abuts against the rotation executing component 3.
The first stop 7 may also be a threaded sleeve. At this time, the mounting shaft 6 is formed with an external thread matching the internal thread of the threaded sleeve. Further, the threaded sleeve is rotated to move the threaded sleeve on the mounting shaft 6, and finally the purpose of locking the rotation actuator 3 is achieved.
Wherein, elasticity stop collar and threaded sleeve all can be formed with handheld portion 701 at the tip to make things convenient for its dismouting of installing axle 6 relatively. Moreover, the arrangement of the handheld part 701 can avoid the contact with the rotary executing component 3 when the first stop part 7 is disassembled and assembled, so that the use safety is ensured, and the collision of the rotary executing component 3 is avoided.
Of course, the first stopper 7 is not a necessary component. For example, the rotary actuator 3 may be welded to the mounting shaft 6. Alternatively, the rotary actuator 3 may be formed with an opening that is an interference fit with the mounting shaft 6.
Further, the mounting shaft 6 is a stepped shaft, comprising a first shaft section 601 and a second shaft section 602. Wherein the rotation executing part 3 is mounted on the first shaft section 601 and the first stopper 7 is mounted on the second shaft section 602. The rationality of the arrangement of the rotation performing part 3 and the first stopper 7 can be further ensured by using a stepped shaft.
When the lock cylinder installation body 2 is matched with the installation hole in shape, please refer to fig. 1 and fig. 2, at this time, a second limit step 14 is formed in the installation hole, the end surface of the lock cylinder installation body 2 abuts against the second limit step 14, and then a certain gap is formed between the end surface of the lock cylinder installation body 2 and the end surface of the installation sleeve 1. When the driving shaft 4 enters the installation sleeve 1, the driving shaft can completely pass through the lock cylinder installation body 2 and enter the gap, and therefore the lock cylinder installation body 2 and the driving shaft 4 are fully matched.
Wherein, the 'shape matching of the lock cylinder mounting body 2 and the mounting hole' refers to: when the mounting hole is a cylindrical hole, the external profile of the lock cylinder mounting body 2 is also in a corresponding cylindrical shape; when the mounting hole is a rectangular column hole, the external profile of the lock cylinder mounting body 2 is also in a corresponding rectangular column shape; when the mounting hole is a special-shaped column hole, the external profile of the lock cylinder mounting body 2 is also in a corresponding special-shaped column shape. When the mounting hole is the cylinder hole, and the external profile of the lock cylinder mounting body 2 is also corresponding cylindricly, adopt interference fit between lock cylinder mounting body 2 and the mounting hole this moment preferentially to avoid the lock cylinder mounting body 2 and the mounting hole to take place relative rotation.
In addition, a third limit step 15 is formed in the mounting hole, and the end surface of the sealing element 5 abuts against the third limit step 15. Further, the relative installation position between the key cylinder mounting body 2 and the seal member 5 can be defined by the third limit step 15.
The above-mentioned rotation performing part 3 may be at least one of a rotating knife, a rotating hook, a rotating claw, a rotating stick, or a rotating paddle, and is not limited by way of example herein. For example, for products such as a soybean milk machine, a wall breaking machine, a juice extractor and the like, the rotary executing component 3 generally adopts a rotary knife; the rotary executing component 3 of the products such as a flour-mixing machine, a pretreatment system of crop fermentation raw materials, a powder coating mixing machine and the like generally adopts a rotary hook; for products such as a superhard abrasive material rotating machine, an eggbeater, a food processer, a biological fertilizer rotating machine and the like, the rotating execution part 3 generally adopts a rotating claw; in addition, a rotary rod and a rotary blade are often used as the rotary actuator 3 in blenders, reaction vessels, and blenders.

That is, when the driving shaft 4 and the rotary head are mounted, the second magnetic member 8 and the first magnetic member 10 generate a magnetic attraction force attracting each other by a magnetic field, see fig. 11.
Referring further to fig. 11, a certain gap may exist between the first magnetic member 10 and the second magnetic member 8, so as to prevent the first magnetic member 10 and the second magnetic member 8 from generating a frictional force when they are directly contacted with each other. Moreover, a certain gap is reserved between the first magnetic element 10 and the second magnetic element 8, and a sealing member, such as a sealing gasket, located between the first magnetic element 10 and the second magnetic element 8 can be additionally provided. Further, a gap between the first magnetic member 10 and the second magnetic member 8 is not necessarily present.
