Description

Wrench structure

This creation is related to a wrench structure, especially a wrench structure in which the first connecting surface and the second connecting surface are arced or arc-shaped connecting the first surface and the first recessed portion, and the third connecting surface And the fourth connecting surface are arced or arc-shaped connecting the second surface and the second recessed portion, and the shank can bear the moment of force from the first connecting surface, the second connecting surface, the third connecting surface and The fourth connecting surface and the effective arc surface are dispersed to the two ends of the handle, and the handle has better torsion resistance.

According to what we have previously known, the commonly used wrench structure is also the previous patent application filed by the applicant. For example, Taiwan Patent Case No.: 099209977, Certificate No.: M392042, Patent Name: Ratchet wrench structure, a ratchet wrench structure, and its series It includes: a body 10, one end of the body 10 is provided with a working end 11, the working end 11 is provided with a first accommodating groove 111 and a second accommodating groove 112, the first accommodating groove 111 and the second accommodating groove The grooves 112 are in communication with each other. The second accommodating groove 112 is provided with a third accommodating groove 113 with a smaller diameter. The third accommodating groove 113 makes the second accommodating groove 112 and the outside of the main body 10 appear In the same way, the second accommodating groove 112 is provided with two symmetrical fourth accommodating grooves 114 on the peripheral surface of the bottom edge of the second accommodating groove 112 near the handle 12, and the two fourth accommodating grooves 114 are spaced apart. The receiving groove 114 communicates with the second receiving groove 112; the other end of the body 10 is provided with a handle 12, and the upper side of the handle 12 is recessed with a first recessed area 121 whose range is slightly smaller than that of the handle 12. A first mark 122 is protrudingly provided in a recessed area 121.

But the shortcomings of this conventional wrench structure are:

There is a height difference between the upper side of the handle 12 and the first recessed area 121, but there is no arc-shaped connecting surface between the upper side of the handle 12 and the first recessed area 121. The upper side surface and the first recessed area 121 are only connected with a chamfer structure. When the ratchet wrench is rotated, the middle part of the handle 12 is a place that bears a greater torque. The handle 12 is connected to the first recessed area. The force received by 121 cannot be effectively distributed to the acting 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 distributed to the two ends of the handle 12. The bearing torque of the part 12 is insufficient.

In view of the shortcomings of the above-mentioned conventional structure, the creator has finally produced a product with a wrench structure that can solve the disadvantages of the conventional structure after 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 recessed area are only connected with a chamfered structure, and the force borne by the handle and the first recessed area cannot be effectively distributed to the acting end and the handle At the other end of the department. In the wrench structure of this creation, the first connecting surface and the second connecting surface are arced or arc-shaped connecting the first surface and the first recessed portion, and the third connecting surface and the fourth connecting surface are arced surfaces Or connect the second surface and the second recessed portion in an arc shape, and the torque of the handle can be effectively arced 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 better torsion resistance.

A wrench structure, which includes: a system It is provided with an acting end, a handle, a first surface and a second surface; 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 The 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 Set 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, the second recessed portion is provided with two third arc surfaces, the The second recessed portion is provided with a fourth arc surface, the fourth arc surface is set between the two third arc surfaces, and the length directions of the second third arc surface and the fourth arc surface extend along the shank Longitudinal direction.

The first connecting surface and the second connecting surface are arced or arc-shaped connecting the first surface and the first recessed portion, and the third connecting surface and the fourth connecting surface are arced or arc-shaped connecting the second Surface and the second recessed portion, when the body is rotated, the bearing moment of the handle can be effectively distributed 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, the handle of the main body can withstand the torsion better when it is rotated.
