Detailed Description

The utility model is further described below with reference to the drawings and specific examples.

Examples

As shown in fig. 1, the labor-saving wire plier comprises a plier body 1, a single plier handle 2 and a single plier head 3.

As shown in fig. 2, the pliers head of the pliers body 1 sequentially comprises a pliers head 4, a connecting part 5 and a pliers handle 6 from front to back, the pliers head 4, the connecting part 5 and the pliers handle 6 are of an integrated structure, a plurality of first saw-tooth-shaped grooves 7 are formed in the front end of the inner wall of the pliers head 4, and a first cutting edge 8 is formed on the front surface of the rear end of the inner wall of the pliers head 4.

The front surface of the connecting part 5 is provided with a first hinge shaft 9 and a second hinge shaft 10 in sequence from front to back.
