The utility model has the following beneficial effects:

1. when the welding electrode holder is used, the outer pipe surface of the sleeve is respectively welded at the positions of a bent handle jaw and a support jaw of the welding electrode holder, then a thumb pushes a bolt rod, the end part of the bolt rod is connected with a push plate, the push plate can tightly press a compression spring, a strip-shaped sliding groove on the bolt rod, a welding rod insertion hole at the top and a welding rod insertion hole at the bottom on the sleeve are in a penetrating structure, then a metal rod of the welding rod penetrates through the welding rod insertion hole at the bottom of the sleeve, the metal rod penetrates through the strip-shaped sliding groove of the bolt rod and finally penetrates out of the welding rod insertion hole at the top of the sleeve, then the bolt rod is loosened, the compression spring can bounce the bolt rod through the push plate, the groove surface at the leftmost side of the strip-shaped sliding groove extrudes the metal rod of the welding rod, the welding rod is fixed on the sleeve, the installation of the welding rod is completed, and the welding work can be carried out.

2. According to the welding rod mounting structure, the bolt assembly penetrates into the strip-shaped sliding groove, the bolt rod can be prevented from rotating in the sleeve through the bolt assembly, a limiting effect is achieved, the spring is mounted in the sleeve, the spring pushes the bolt rod, and the welding rod can be rapidly mounted.

3. The welding clamp has the characteristics of simple structure, convenience in operation and the like, the waste welding clamp can be continuously used by adopting the device, and the device is only required to be welded between the bent handle jaw and the straight jaw of the welding clamp, so that the waste of the welding clamp is avoided, and the expenditure is saved.
