Curved jaw locking pliers

Abstract

Curved jaw locking pliers comprise an upper pliers arm and a lower pliers arm. The upper pliers arm is connected with a pliers jaw through a rivet. A semicircular toothed pressing block is arranged on the lower portion of the pliers jaw. The lower pliers arm is fixed below the upper pliers arm. The lower pliers arm is connected with a pliers jaw through a rivet, and a semicircular toothed pressing block is arranged on the upper portion of the pliers jaw. A movable pressing rod is fixed to the lower pliers arm, and is connected with the lower pliers arm through a rivet. The upper pliers arm is provided with an adjusting nut which is located at the end of the upper pliers arm. The movable pressing rod is arranged at the end of the lower pliers arm. The semicircular toothed pressing blocks are vertical type sawteeth. According to the curved jaw locking pliers, due to the fact that an adjusting nut is arranged at the end of the upper pliers arm, the clamping force of the curved jaw locking pliers can be further controlled, and the curved jaw locking pliers can be used for processing workpieces made of different materials with different strengths; the teeth are vertical sawteeth, so that the biting force of the curved jaw locking pliers can be reinforced; and the workpieces can be clamped more tightly, and an operator can operate the pliers with less effort.

Description

technical field [0001] The invention relates to a processing tool, in particular to a transfer round pliers. Background technique [0002] At present, many pliers are widely used in various fields. In the actual processing process, various pliers need to be used. Different pliers can play different roles. At present, many pliers tend to be clamped when clamping tools. It is easy to fall off, resulting in cracks in the workpiece, affecting the secondary processing of the workpiece, resulting in the inability of further processing of the workpiece, and affecting the production progress of the enterprise. Many pliers still have tooth patterns on the jaws, but many The tooth pattern will wear out after a short period of time. In this case, the workpiece will not be clamped tightly, and many workpieces will fall off the processing machine, resulting in damage to the workpiece, making the operator unable to exert force well, and the operation is time-consuming and The clamping ef...

[0002] At present, many pliers are widely used in various fields. In the actual processing process, various pliers need to be used. Different pliers can play different roles. At present, many pliers tend to be clamped when clamping tools.

Many pliers still have tooth patterns on the jaws, but many The tooth pattern will wear out after a short period of time. In this case, the workpiece will not be clamped tightly, and many workpieces will fall off the processing machine, resulting in damage to the workpiece, making the operator unable to exert force well, and the operation is time-consuming and Clamping effect is not very good
