Description

Wrench structure

The present invention relates to a wrench structure, especially a wrench structure in which the first connecting surface and the second connecting surface are arc surfaces or arc-shaped connecting the first surface and the first recess, and the third connecting surface And the fourth connecting surface is an arc surface or an arc connecting the second surface and the second concave portion, and the bearing moment of the handle can be determined by the first connecting surface, the second connecting surface, the third connecting surface and the The fourth connecting surface and the effective arc surface are distributed to the two ends of the handle portion, and the handle portion has a better torsion resistance.

According to our previous knowledge, the conventional wrench structure is also the previous patent applied by the applicant, such as Taiwan patent case number: 099209977, certificate number: M392042, patent name: ratchet wrench structure, a ratchet wrench structure, which is It includes: a main body 10, one end of the main body 10 is provided with an action end 11, the action end 11 is provided with a first accommodating slot 111 and a second accommodating slot 112, the first accommodating slot 111 and the second accommodating slot 111 The grooves 112 are communicated with each other. The second accommodating groove 112 is provided with a third accommodating groove 113 with a smaller diameter. In the same way, the bottom edge of the second accommodating groove 112 is provided with two symmetrical fourth accommodating grooves 114 near the shank 12, and there is a distance between the two fourth accommodating grooves 114. The accommodating groove 114 is communicated with the second accommodating groove 112; the other end of the main body 10 is provided with a handle portion 12, and the upper side surface of the handle portion 12 is concave with a first concave area 121 slightly smaller than the handle portion 12. A first mark 122 is protruded inside a recessed area 121 .

But the lack of this conventional wrench structure is:

There is a height difference between the upper side surface of the handle portion 12 and the first recessed area 121 , but there is no arc-shaped connecting surface between the upper side surface of the handle portion 12 and the first recessed area 121 . The upper side and the first recessed area 121 are connected only by the chamfered structure. When the ratchet wrench is rotated, the middle of the handle 12 is the place where the torque is relatively large, and the handle 12 is connected to the first recessed area. The force borne by 121 cannot be effectively distributed to the action end 11 and the other end of the handle 12, that is, the right end of the handle 12, that is, it cannot be effectively dispersed to both ends of the handle 12. The bearing torque of the part 12 is insufficient.

In view of the lack of the conventional structure mentioned above, the inventor of the present invention has finally developed a product with a wrench structure that can solve the drawbacks of the conventional structure with years of experience in manufacturing, production and design in related industries.

In the conventional wrench structure, the upper side of the handle and the first concave area are only connected by a chamfered structure, and the force on the handle and the first concave area cannot be effectively distributed to the action end and the handle. at the other end of the department. In the wrench structure of the present invention, the first connecting surface and the second connecting surface are arc surfaces or arc-shaped connecting the first surface and the first recessed portion, and the third connecting surface and the fourth connecting surface are arc surfaces Or arc connecting the second surface and the second recessed part, the bearing moment of the handle can be effectively arc surface by the first connecting surface, the second connecting surface, the third connecting surface and the fourth connecting surface Distributed to the two ends of the handle, the handle has a better torsion resistance.

A wrench structure, which includes: a system A working end, a handle, a first surface and a second surface are provided; the first surface is provided with a first recess, a first connecting surface and a second connecting surface; the second surface is provided with a A second concave portion, a third connecting surface and a fourth connecting surface; the first concave portion is provided with two first arc surfaces, the first concave portion is provided with a second arc surface, and the second arc surface is between the two first arc surfaces, the length directions of the two first arc surfaces and the second arc surfaces extend along the length direction of the handle portion, the second recessed portion is provided with two third arc surfaces, the The second concave portion is provided with a fourth arc surface, the fourth arc surface is arranged between the two third arc surfaces, and the length directions of the two third arc surfaces and the fourth arc surface extend along the length of the handle. Longitudinal direction.

The first connecting surface and the second connecting surface are arc surfaces or arc-shaped connecting the first surface and the first recessed portion, and the third connecting surface and the fourth connecting surface are arc surfaces or arc-shaped connecting the second connecting surface When the body is rotated, the bearing torque of the handle can be effectively dispersed by the first connecting surface, the second connecting surface, the third connecting surface and the fourth connecting surface To the two ends of the handle portion, the handle portion of the main body has a better torsional force when it rotates.
