Rolling shaft type tongs

Abstract

The invention relates to a pair of rolling shaft type tongs. The pair of rolling shaft type tongs comprises a tong hook, a tong gill, a handle and a shell enclosing the handle, wherein the tail ends of two arms are connected with a compression spring; two arms of the handle are respectively provided with a row of through holes uniformly distributed along the axial direction; a metal wire is arranged between the two arms of the handle, is spiral and sequentially passes through the through holes; one end of the metal wire is fixedly arranged on the handle, and the other end of the metal wire is connected to a wire spool with a wire winding groove; the wire spool is connected to the shell by virtue of a wire winding shaft and can rotate around the wire winding shaft freely; the periphery of the wire spool is provided with ratchets; the ratchets are matched with pawls on the shell; the pawls are rotatably connected to the shell by virtue of pawl shafts; the shell is provided with a window capable of exposing the wire spool. The pair of rolling shaft type tongs can be used for easily clipping objects with high rigidity and effectively preventing object damage caused by overlarge forces.

Description

technical field [0001] The present invention relates to a hardware appliance, in particular, a pair of pliers. Background technique [0002] Common pliers are composed of a pliers mouth, a pliers plug and a handle. According to the principle of leverage, hold the handle when the object needs to be cut, close the pliers mouth, and use a small force to cut the object, but when cutting objects with greater hardness The user may not be able to easily cut the object; in addition, the distance between the handles is very small. If the force is too strong, it will cause excessive bite at the jaws and damage the object. SUMMARY OF THE INVENTION [0003] In view of the above problems, the purpose of the present invention is to provide a roller type pliers, which can easily cut objects with high hardness and can effectively prevent damage to the objects caused by excessive force. [0004] In order to solve the above problems, the technical scheme of the present invention is as foll...
