Screwdriver structure

The present invention relates to a hand tool, and more particularly to a grip structure for a hand tool.

In general, when the user uses a screwdriver to lock or loosen the screw, the screwdriver must be kept perpendicular to the object to be locked in order to obtain the best locking effect. However, since the grip of the general screwdriver is directly connected to the head of the screwdriver, when the user holds the grip, if it is slightly offset, it will cause the offset of the screwdriver head, but not perpendicular to the locked object. The state, which in turn affects the locking or loosening effect of the locked object.

In addition, when a user uses a screwdriver, if there is no ratchet mechanism, when the user operates the lock with one hand or releases the locked object, the screwdriver may not always rotate in the same direction due to the gesture. After turning to an angle, the driver's head must be removed from the locked object, the gesture must be re-adjusted, and the screwdriver head should be repositioned on the object to be locked, and the action should be repeated until the locked object is completely locked or loosened. inconvenient.

Therefore, an aspect of the present invention provides a driver grip structure, wherein a buffer portion between the body and the hand portion allows the user to use the driver without causing the driver's head to shift even if the angle of the hand grip is shifted. The angular offset can still maintain the vertical state between the screwdriver head and the object to be locked for optimal use.

According to an embodiment of the present invention, a driver grip structure includes a body, a buffer portion, and a hand portion. The system is made of a hard material and the bottom end is provided with a set of sub-heads. The buffer portion is integrally formed with a soft material around the periphery of the body, and the hand portion is made of a hard material and integrally connected with the buffer portion.

According to an embodiment of the invention, the buffer portion has at least one protruding portion extending in a horizontal direction, and the hand portion is integrally formed with the protruding portion of the buffer portion.

According to an embodiment of the invention, the driver grip structure further comprises a cover covering the top end of the body and the buffer portion.

According to an embodiment of the invention, the top end of the body has an annular groove, and the inner surface of the cover has a plurality of engaging portions for engaging in the annular groove of the body, so that the cover covers the top of the body and the buffer portion. At the same time, it can be rotated in motion.

1 is a partial cross-sectional view showing a structure of a driver handle according to an embodiment of the present invention. The driver handle structure 100 includes a body 110, a buffer portion 120, and a hand portion 130.

The body 110 is formed by ejecting a hard material, and the bottom end of the body 110 is configured to assemble the sub-head 200. According to an embodiment of the invention, the driver bit 200 is a ratchet driver. The structure of the ratchet driver is not a technical feature of the present invention and will not be described in detail herein. The buffer portion 120 is integrally formed with a soft material around the periphery of the body 110, and the buffer portion 120 has a plurality of protrusions 122 extending in the horizontal direction. The hand piece 130 is formed in the same manner as the main body 110 by a hard material, and is integrally connected to the protruding portion 122 of the buffer portion 120.

Specifically, in the manufacturing of the driver handle structure 100 of the present invention, the body 110 and the hand portion 130 are respectively injected in an injection manner. Next, a buffer portion 120 is formed by secondarily ejecting a soft material between the main body 110 and the hand portion 130. In this way, the body 110, the buffer portion 120 and the hand portion 130 are integrally formed into a seamless structure.

2 is a view showing a structure of a driver handle according to another embodiment of the present invention. Partial section view. In the present embodiment, the driver handle structure 100 also includes a body 110, a buffer portion 120, and a hand portion 130. The difference from the foregoing embodiment is that when the buffer portion 120 is formed by the second injection, the protruding portion 122 of the buffer portion 120 is embedded in the hand portion 130, thereby increasing the connection stability between the buffer portion 120 and the hand portion 130.

3 is a plan view showing a structure of a driver handle without a cover according to another embodiment of the present invention. Fig. 4 is a cross-sectional view showing the structure of the driver handle of the cover body taken along line A-A of Fig. 3. Figure 5 is a bottom plan view showing the cover of the driver handle structure of Figure 4. Please refer to Figure 2 to Figure 4 at the same time. The driver handle structure 100 includes a body 110, a buffer portion 120, a hand portion 130, and a cover 140.

In the present embodiment, the driver bit 200 assembled at the bottom end of the body 110 is a generally straight-type screwdriver bit. The buffer portion 120 is also made of a soft material and integrally formed around the periphery of the body 110, while the buffer portion 120 has a plurality of protrusions 122 extending in the horizontal direction. The hand piece 130 is formed in the same manner as the main body 110 by a hard material, and is integrally connected to the protruding portion 122 of the buffer portion 120. In addition, the hand portion 130 has a plurality of concave portions 132 on the annular surface, and the intervals between the concave portions 132 are the same. Therefore, the user can hold the hand portion 130 more easily and securely by the finger fitting concave portion 132.

Furthermore, in the present embodiment, the surface of the lid body 140 has an arc shape, and as shown in FIG. 4, a plurality of locking portions 142 are provided on the inner surface of the lid body 140, and each of the card portions 142 has a certain distance therebetween. The cover portion 142 of the cover body 140 is provided with an annular recess 112, so that the cover 140 can be locked in the annular groove 112 at the top end of the body 110 by the locking portion 142, thereby making the cover 140 Covering the top of the body 110 and the buffer portion 120. When the cover 140 is locked in the annular groove 112 at the top of the body 110 by the locking portion 142, the cover 140 can be independently and independently rotated on the top of the body 110. The body 110 is not driven to rotate, and the screwdriver head 200 disposed at the bottom end of the body 110 is not displaced or rotated.

Usually, when a user uses a general screwdriver, if there is no ratchet mechanism, when the user operates the lock with one hand or releases the locked object, the screwdriver cannot always rotate in the same direction due to the gesture, so when going to a certain After an angle, it is very inconvenient to remove the driver's head from the locked object, re-adjust the gesture, and reposition the screwdriver head on the locked object. However, the starter head grip structure 100 of the present invention is provided with a movable rotating cover body 140. When the user needs to adjust the gesture relationship, the palm can be directly pressed against the surface of the cover body 140. The 200 is still above the locked object, and the cover 140 is rotated by the palm. Since the cover 140 can be independently and flexibly rotated on the top of the body 110, the body 110 is not rotated, and the bottom of the body 110 is not formed. The end of the screwdriver bit 200 is offset or rotated. In this way, it is not necessary to repeatedly reposition the screwdriver head 200 away from the locked object, which makes the use easier.

In general, when the user uses a screwdriver to lock or loosen the screw, the screwdriver must be kept perpendicular to the object to be locked in order to obtain the best locking effect. However, it is often easy to cause an angular offset when holding the grip, so that the screwdriver head cannot be perpendicular to the object to be locked. The handle portion 130 of the present invention has a space 124 between the hand portion 130 and the body 110 because the hand portion 130 of the driver handle structure 100 is integrally formed with the protrusion 122 of the buffer portion 120 instead of being directly connected to the body 110. As shown in FIG. 4, the space 124 includes a space between the two protrusions 122 and a space above and below the single protrusion 122. The material of the buffer portion 120 is relatively soft, and the space 124 is matched. Therefore, the offset of the hand portion 120 can be absorbed by the buffer portion 120 during use without directly affecting the offset of the body 110, and is not caused to be disposed on the body 110. The bottom end of the screwdriver head 200 is offset. In other words, when the user uses the screwdriver having the driver handle structure 100 of the present invention, even the hand holding portion 130 When the offset occurs, the driver head 200 assembled at the bottom end of the body 110 can still maintain a vertical relationship with the object to be locked, and can obtain an optimal locking or loosening effect.

Figure 6 is a plan view showing a structure of a driver handle without a cover according to still another embodiment of the present invention. In the present embodiment, the driver handle structure 100 also includes a body 110, a buffer portion 120, and a hand portion 130. The difference from the foregoing embodiment is that the protruding portion 122 of the buffer portion 120 is continuously surrounded between the buffer portion 120 and the hand portion 130. In other words, the buffer portion 120 has only one protrusion 122.
