Automatic adjusting locking pliers

Abstract

The invention relates to automatic adjusting locking pliers. The automatic adjusting locking pliers are provided with an automatic adjusting device on the basis of the conventional locking pliers to enable the locking pliers to clamp objects with different sizes without adjusting the locking pliers, can adjust a clamping force as required. The automatic adjusting locking pliers solve the problems that the conventional locking pliers have troubled operation, the clamping force of the conventional locking pliers is difficult to control and the like, and belong to the field of machinery. The automatic adjusting locking pliers of the invention comprise a main plier body and an auxiliary plier body, wherein a front end of the main plier body is connected with a jaw (1) and is also hinged with a jaw (2) corresponding to the jaw (1); the other side of the jaw (2) is hinged at the front end of the auxiliary plier body; a connecting rod with a meshing block and an adjusting screw, a meshing pressing block and a guide locking device are arranged between the main plier body and the auxiliary plier body; one end of the connecting rod is hinged with the auxiliary plier body, while the other end is hinged with the meshing pressing block; the meshing pressing block is also hinged with the guide locking device; the inside of the main plier body is provided with a guide rod; and the guide locking device can slide freely on the guide rod, and can be locked on a corresponding position when the meshing pressing block presses. The automatic adjusting locking pliers have the characteristics of compact structure, large adjustable range of the clamping force, strong reliability, convenient use and the like.

Description

Technical field: [0001] The invention belongs to the field of machinery and relates to a pair of pliers that can be automatically adjusted to clamp objects of different sizes, and whose clamping force can be continuously adjusted as required. Background technique: [0002] The present invention greatly improves the positioning of the support rod of the pliers in the main pliers, so that the pliers can automatically clamp objects of various sizes, and the clamping force can be kept constant and adjustable during work. . [0003] The positioning of the support rod of the existing vise in the main tong body is adjusted by the adjustment screw mounted on the main tong body. Therefore, each time the vise is used, the user is required to try the clamp first, and then adjust to determine The specific position of one end of the screw can be used normally. If the size of the clamped object is different, it needs to be adjusted again. The working efficiency is extremely low, and th...

AI Technical Summary

Problems solved by technology

The working efficiency is extremely low, and the clamping force is difficult to control

In many cases it is not even possible to use

Obviously, the existing pliers have to carry out complex work such as trial clamping and screw adjustment before each use, which is a great defect for the pliers themselves.
