Problems solved by technology

In the prior art, the staff usually use the tip of the crowbar to pry and pull the spring, but ordinary crowbars are greatly affected by the terrain and geographical location, and often cannot find a suitable fulcrum, so they can only be used together by multiple crowbars. Collaboration is completed, the use process is labor-intensive and time-consuming, and improper force may easily cause injury to the staff

Abstract

The invention relates to a multifunctional crowbar comprising a crowbar body and a hook. The hook comprises a vertical part and a bent part. The vertical part of the hook is provided with a thread. The crowbar body is provided with ducts, the adjacent ducts are equally spaced, the vertical part of the hook is in clearance fit with the ducts, and the vertical part of the hook is perpendicularly connected with the crowbar body through a nut. The multifunctional crowbar is simple in structure and reasonable in design; the hook is added to the multifunctional crowbar, so that workers can hook and pull a spring through the crowbar conveniently.

Description

technical field [0001] The invention relates to a multifunctional crowbar. Background technique [0002] At present, at the substation construction site, when it is necessary to overhaul the spring of the spring mechanism switch or install the large spring of the spring mechanism, the spring needs to be stretched under force. In the prior art, the staff usually use the tip of the crowbar to pry and pull the spring, but ordinary crowbars are greatly affected by the terrain and geographical location, and often cannot find a suitable fulcrum, so they can only be used together by multiple crowbars. The cooperation is completed, the use process is labor-intensive and time-consuming, and improper force may easily cause injury to the staff. Contents of the invention [0003] The object of the present invention is to provide a multifunctional crowbar. [0004] In order to solve the problems of the technologies described above, the technical scheme adopted in the present inven...
