Novel curved jaw locking pliers

Abstract

The invention provides a pair of novel curved jaw locking pliers, which comprises an upper plier arm and a lower plier arm, wherein an upper jaw is fixed at the head part of the upper plier arm; a lower jaw is arranged below the upper jaw, and connected with the lower plier arm through a rivet; a movable pressing rod is arranged above the lower plier arm; the other end of the movable pressing rod is fixed in the lower plier arm; a tension spring is arranged in the middle of the upper plier arm and connected with the lower jaw; an adjusting nut is arranged at the tail part of the upper plier arm; and a nickel plating coating is arranged on each of the upper jaw and the lower jaw. According to the novel curved jaw locking pliers, the tension spring is arranged in the middle of the upper plier arm, so that physical exhaustion of an operator during the process of clamping a workpiece is reduced, the processing speed of the operator is increased, and a certain clamping force is kept between the two jaws; the opening degree of the jaw can be adjusted, and the curved jaw locking pliers can meet processing needs of workpieces of different thicknesses since the adjusting nut is arranged at the tail part of the upper plier arm; and since the nickel plating coatings are arranged on both the upper jaw and the lower jaw, the corrosion of the workpeice to the jaws can be resisted and the service life of the curved jaw locking pliers is prolonged greatly.

Description

technical field [0001] The invention relates to a processing tool, in particular to a novel round-nosed pliers. Background technique [0002] Vigorous pliers can be used to clamp the workpiece, and can be used to fix the workpiece during welding. Different pliers have different functions. At present, many pliers require the operator to operate with both hands, and the other hand is very free, resulting in Increase the labor intensity of the operator, reduce the work efficiency of the operator, and many workpieces need to be processed in the next step during processing. The current forceps often leave a large number of tooth marks on the surface of the workpiece, resulting in the surface of the workpiece The damage affects the processing accuracy of the workpiece, and cannot guarantee the next processing quality of the workpiece. The jaws of many pliers are often severely corroded due to long-term contact with the workpiece, resulting in the inability of the pliers to clamp s...
