Description

   Hand tool turning part structure   

The invention relates to the structure of a hand tool rotating part, which refers to a hand tool rotating part structure which is provided with a fitting part. The fitting part includes a first driving part, a second driving part, a first receiving part and The second accommodating part, the system has both a general turning method and a screwing member with a rounded corner.

According to my previous knowledge, the structure of the rotating part of a conventional hand tool, such as Taiwan patent application number: 089206331, patent name: Improved sleeve structure, the patent case structure is: an improved sleeve structure, which is mainly characterized by: The sleeve 20 is formed by a large convex arc surface 22 and a small concave arc surface 21 on each other. The large convex arc surface 22 is provided with a large number of oblique teeth 23 and a large number of reverse inclines. The teeth 24, the oblique teeth 23 and the reverse oblique teeth 24 are arranged staggered, and the convex arc surface 22 forms a chamfered inclined surface 25.

However, the lack of the structure of the rotating part of this hand tool lies in:

The convex convex surface 22 is provided with a plurality of oblique teeth 23 and reverse oblique teeth 24, and the sleeve 20 is engaged with the oblique teeth 23 and reverse oblique teeth 24 on the convex convex surface 22 when rotating. On the hexagonal peripheral surface 31 of the screwing member 30, but the oblique teeth 23 and the reverse oblique teeth 24 are in a sharp angle, the oblique teeth 23 and the reverse oblique teeth 24 easily make the screwing member 30 The hexagonal peripheral surface 31 is bitten by the oblique teeth 23 or the reverse oblique teeth 24 during rotation.

Another Taiwan patent application number: 105205070, certificate number: M528831, patent name: progressive wrench structure, the first end angle 23 and the second end angle 32 are pointed, the first end angle 23 and the first The two end angles 32 are the oblique teeth 23 and the reverse oblique teeth 24, which are identical to the application number 089206331, and they are arranged in a staggered arrangement, so that it is easy to cause bite marks on the hexagonal peripheral surface of the screwed part and also have the same defects.

Yet another U.S. patent case number: US2006 / 0117917A1, that is, Taiwan patent certificate number: M270886, patent name: sleeve with damaged nut head, please supplement the fifth and seventh figures of the bulletin. When the sleeve 20 is engaged with the nut head 40, the latching protrusion 24 of the engaging hole 22 is locked at the center of each side of the nut head 40 to drive the nut head 40 to rotate, but the The latching oblique projection 24 is sharp-angled, and the rotational torque of the latching oblique projection 24 is insufficient and will cause bite marks on the nut head 40.

In view of the lack of the structure of the rotating part of the hand tool as described above, the inventor finally made a product of the hand tool rotating part structure which can solve the shortcomings of borrowing through years of manufacturing experience in related industries.

The conventional rotating part is used to open the screwed part with rounded corners, which will cause bite marks on the side surface of the screwed part during general rotation. The hand tool rotating part structure of the present invention is provided with a sleeve part. The fitting part includes a first driving part, a second driving part, a first accommodating part and a second accommodating part. The system has both a general rotation method and a screwing member with a rounded corner. .

A hand tool turning part structure includes: a sleeve part is provided in the system, and the sleeve part includes a first driving part, a second driving part, a first receiving part and a second receiving part, The first driving part, the first accommodating part, the second driving part, and the second accommodating part are sequentially arranged in a ring shape, and the first driving part and the second driving part are each three and spaced apart from each other. A first accommodation portion and a second accommodation portion are arranged between the first driving portion and the second driving portion, and the first accommodation portion and the second accommodation portion are arranged in a ring shape at intervals. The first accommodating portion and the second accommodating portion are each three.

The system can be screwed clockwise and unscrewed the screwed part. When the screwed part is rotated counterclockwise, the three first action parts are only for assisting the force and are unlikely to cause the screwed part. There are bite marks on the side surface. When the screwing part is rounded, the three first action portions can engage the three side surfaces of the screwing part and rotate with a chance of biting into the three side surfaces. In this way, the screwing part has both the general rotating method and the rotating effect of the screwing part with rounded corners.

In order to fully understand the effects of the present invention by members of the Bureau and those skilled in the art, the structure and composition of the present invention are explained in conjunction with the drawings and figures, but the following are only used to explain the implementation of the present invention. For example, it is not intended to limit the present invention in any form, and any modification made under the spirit of the present invention should still fall within the protection scope of the present invention.
