Problems solved by technology

[0003] The handles of existing wrenches are generally fixed in size and shape. One wrench can meet two types of screws at most. When there are many screw specifications and models, the user must carry multiple wrenches, and frequent replacement of wrenches is time-consuming. It is laborious and seriously affects work efficiency. Although there are ratchet wrenches on the market, the structure of this type of wrench is complicated and the noise is loud when used, which affects the user experience of users.

Abstract

The invention relates to a two-way wrench comprising a wrench body, a wrench head sleeve, a needle bearing, a wrench head block sleeving a nut and a clamp spring. A through hole is formed in the middle of the wrench head sleeve. A protruding edge is formed at one end of the inner wall of the through hole. A first slot in circle is formed in the center of the inside wall of the protruding edge. The joint of the wrench head sleeve and the wrench body is provided with a rotary knob. A shifting rod is fixed at the lower end of the rotary knob and penetrates the side wall of the wrench head sleeve. The needle bearing comprises a needle sleeve and needles uniformly embedded in the side wall of the needle sleeve. A notch is formed in the outside wall of the needle sleeve. The needle bearing is embedded in the wrench head sleeve. One end of the needle bearing is abutted against the protruded edge. The shifting rod extends in the notch. One end of the outside wall of the wrench head block is provided with a third slot. The wrench head block is embedded in the needle bearing. The axial positions of the wrench head block and the wrench head sleeve are fixed with the aid of the clamp spring mounted in the second slot and the third slot. The two-way wrench is wide in range of application.

Description

technical field [0001] The invention relates to a wrench structure, in particular to a two-way wrench. Background technique [0002] In people's daily life, it is often necessary to screw bolts, screws, nuts and other threaded openings or socket fasteners that hold the bolts or nuts tightly. External force can be easily applied to help people tighten bolts or nuts to hold bolts or nuts. [0003] The handles of existing wrenches are generally fixed in size and shape. One wrench can meet two types of screws at most. When there are many screw specifications and models, the user must carry multiple wrenches, and frequent replacement of wrenches is time-consuming. It is laborious and seriously affects work efficiency. Although there are ratchet wrenches on the market, the structure of this kind of wrench is complicated, and the noise is relatively large when used, which affects the user experience of users. Contents of the invention [0004] In order to solve the above-mentio...
