Description

Technical Field

[0001] The utility model belongs to the technical field related to wrenches, and in particular relates to a wrench used in a narrow space. Background Art

[0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts and other threaded fasteners that hold bolts or nuts through openings or holes. Wrenches are usually made of structural steel made of carbon or alloy materials. Wrenches are usually made with openings or holes for clamping bolts or nuts at one or both ends of the handle. When used, the handle is held and external force is applied to rotate the wrench to achieve the purpose of twisting the bolts or nuts. The existing wrench structure is fixed, and some operating positions have narrow spaces, so the wrench cannot be put in, making it difficult to operate, and it is not easy to operate in a narrow space. A wrench that can be used in a narrow operating space proposed in patent CN202222692274.4, by setting a sleeve that is slidably connected on the wrench arm, and cooperating with a rotatable handle, can adjust the wrench arm length and handle angle according to actual space requirements. It is particularly suitable for nut removal work in a narrow space, easy to adjust, and can achieve a large degree of steering. Although this patent meets the requirements of use to a certain extent, it is found in actual use that the wrench is mainly suitable for situations where the wrench can be lowered axially in the fixed screw. It still cannot meet the use requirements when there is no axial space to put the wrench.

[0003] In view of this, the present utility model is proposed. Utility Model Content
