Abstract

The invention discloses foldable pliers. The foldable pliers comprise a first plier head and a second main handle; the middle portion of the first plier head is connected to the middle portion of a second plier head in a clamped manner through a first pin shaft; one end of the second plier head is fixedly connected with second pin shafts and fixing holes; the second pin shafts are fixedly connected with one end of a first main handle through one side of connecting blocks; the upper surface of the first main handle is provided with a groove; springs are fixedly connected to the bottom of the groove; and a fixing block is fixedly connected to the other end of the first main handle. According to the foldable pliers, due to the arrangement that the second pin shaft is connected with the first main handle and the second main handle, the main handles of the pliers can be folded, the pliers can be carried better, the effect that a person is accidently pinched is not prone to be caused, and accidental injuries are avoided; and due to the arrangement that clamping holes in a buckle plate are connected with a clamping block in a buckled manner, the first main handle and the second main handle can be closed more tightly, and the pliers are folded more conveniently through the second pin shafts and third pin shafts.

Description
