Clamping pincers for rod machining

Abstract

The invention relates to the field of rod machining, and discloses clamping pincers for rod machining. The clamping pincers comprise two hinged pincer handles (1) and two clamping parts (2) arranged at the front ends of the two pincer handles (1) correspondingly. The clamping pincers are characterized in that the two clamping parts (2) are each provided with an arc jaw (20) used for clamping a rod, and the two clamping parts (2) are detachably arranged at the front ends of the two pincer handles (1) correspondingly. The clamping parts are detachably arranged at the front ends of the two pincerhandles of the clamping pincers for rod machining correspondingly, each clamping part comprises a connecting mechanism and the corresponding arc jaw, the arc jaws achieve the rotatable effect by being provided with multiple locking mechanisms, then the direction of each arc jaw can be changed so as to adapt to the restriction of space, environments and other conditions, and operation of people isgreatly facilitated.

Description

technical field [0001] The invention relates to the field of bar material processing, in particular to a clamping pliers for bar material processing. Background technique [0002] Clamping pliers are a hand tool used to clamp and fix workpieces, and are widely used in industrial production. In the process of bar material processing, heat treatment processes such as normalizing, annealing and tempering are usually required, which will cause the bar material to reach a very high temperature, so it is necessary to use clamping pliers to clamp the bar material for operation. The jaws of the existing clamping pliers are all fixed, and the direction of the jaws is usually perpendicular to the handle and cannot be changed. Under normal circumstances, the use of clamping pliers whose jaw direction is perpendicular to the pliers handle often cannot be easily clamped, which has an adverse effect on the work of the operator. Contents of the invention [0003] The object of the pres...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a clamping pliers for bar processing in order to overcome the problem that the jaws of the clamping pliers are fixed and set so that the direction of the jaws cannot be changed in the prior art. The front ends of the handles are detachably provided with clamping parts respectively, and the clamping parts include connecting mechanisms and arc-shaped jaws. The arc-shaped jaws are rotatable by setting multiple locking mechanisms, and then can be changed. The direction of the arc-shaped jaws is adapted to the constraints of space and environment, which greatly facilitates people's operation
