A new type of three-dimensional wrench, which has a working part of the three-dimensional wrench, and a convex and concave concave-convex groove that fits each other between the working part and the handle part, and fits the convex and concave parts between the working part and the handle part together. The working part and the handle part are hinged together by a pin; since the working part and the handle part of the wrench can be rotated in different plane ranges, this kind of wrench can be used in a certain three-dimensional space, which overcomes the existing wrench Existing inconvenient defects in the use of three-dimensional space.
Description
technical field [0001] The invention relates to a wrench, in particular to a novel three-dimensional wrench, which belongs to the technical field of hardware tools. Background technique [0002] A wrench is a commonly used hardware tool. At present, in the structure of the wrench, the working part of the wrench and the body of the wrench are in the same plane. Although the wrench with this structure has the advantage of simple structure, in actual work, due to different space restrictions , Sometimes it is impossible for the hand, the wrench body and the working part to be on the same plane, so the existing wrench has the disadvantages of inconvenient work and inability to use in some three-dimensional spaces. Contents of the invention [0003] The object of the present invention is to provide a new type of three-dimensional wrench, which overcomes the disadvantages of the existing wrench in structure: it cannot be used in a three-dimensional space and it is inconvenient ...
