Abstract

The invention provides a wrench. The wrench comprises a handle, and further comprises a sleeve and a connecting plate, wherein a central hole of the sleeve is blocked with the head of a bolt; one endof the connecting plate is fixedly connected with the sleeve; one end, away from the sleeve, of the connecting plate is perpendicularly equipped with a first connecting structure; one end of the handle is perpendicularly equipped with a second mounting structure; and the first mounting structure is connected with the second mounting structure. The wrench provided by the invention is provided withthe first mounting structure which is perpendicularly connected with the connecting plate, and the second mounting structure which is perpendicularly connected with the handle; the first mounting structure is connected with the second mounting structure, so that connection between the connecting plate and the handle is realized; and moreover, bending is formed between the connecting plate and thehandle, so that the wrench can be suitable for tightening and loosening the bolt when the bolt mounting surface is lower than the peripheral plane, and therefore, the problem of tightening and loosening the bolt when the bolt mounting surface is lower than the peripheral plane is solved better.

Description

technical field [0001] The invention relates to the technical field of fastener loosening tools, in particular to a wrench. Background technique [0002] When the bolt mounting surface is lower than the surrounding plane, it is more difficult for the commonly used flat wrench to tighten the bolt. Therefore, how to design a wrench to solve the problem of the tightness of the bolt when the bolt mounting surface is lower than the surrounding plane has become a technical problem urgently needed by those skilled in the art. Contents of the invention [0003] The invention provides a wrench to solve the problem of bolt tightness when the bolt mounting surface is lower than the surrounding plane. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A wrench, which includes a handle, and also includes a sleeve and a connecting plate, the central hole of the sleeve is used to engage with the bolt head, one end of the con...
