Novel sharp-mouth locking pliers

Abstract

The invention discloses a pair of novel sharp-mouth locking pliers. The novel sharp-mouth locking pliers comprises an upper pliers arm and a lower pliers arm, wherein the upper pliers arm is connected with an upper pliers mouth through a rivet; a lower pliers mouth is arranged below the upper pliers mouth, and is connected with a lower pliers arm through a rivet; a movable pressing rod is arranged above the lower pliers arm, and is connected with the upper pliers arm; a tension spring is arranged above the movable pressing rod, and is connected with the lower pliers mouth; an adjusting nut is arranged in the middle of the upper pliers arm; the movable pressing rod is provided with a rubber coating layer; the rubber coating layer is positioned at the tail part of the movable pressing rod; and the upper pliers mouth and the lower pliers mouth are both provided with linear saw teeth. As the adjusting nut is arranged in the middle of the upper pliers arm, the locking pliers can adapt to workpieces with different thicknesses; as the rubber coating layer is arranged at the tail part of the movable pressing rod, the frictional coefficient of the movable pressing rod can be increased, and users are not liable to slip in the use process; and the linear saw teeth are arranged in the pliers mouths, so that the occlusion degree of the sharp-mouth locking pliers can be improved, and the sharp-mouth locking pliers cannot cause the drop of the workpieces in workpiece machining.

Description

technical field [0001] The invention relates to a processing tool, in particular to a novel needle-nose pliers. Background technique [0002] The application range of needle-nose pliers is getting wider and wider. Many needle-nose pliers are used to clamp workpieces, especially for some smaller workpieces. Ordinary wide-mouth pliers often cannot grip well, and can only rely on The needle-nose pliers are used for clamping. At present, many needle-nose pliers cannot be clamped well, resulting in many workpieces not being able to be processed well. Many workpieces have fallen off the machine, which brings The difficulty has affected the processing speed of the workers and delayed the production plan of the enterprise. The movable pressure bar of many pliers is relatively long, and it often slips when the personnel operate, which affects the processing of the operator. At present, there are some needle-nose pliers. The jaws are particularly prone to wear and tear during use, wh...

[0002] The application range of needle-nose pliers is getting wider and wider. Many needle-nose pliers are used to clamp workpieces, especially for some smaller workpieces. Ordinary wide-mouth pliers often cannot grip well, and can only rely on The needle-nose pliers are used for clamping. At present, many needle-nose pliers cannot be clamped well, resulting in many workpieces not being able to be processed well. Many workpieces have fallen off the machine, which brings The difficulty has affected the processing speed of the workers and delayed the production plan of the enterprise. The movable pressure bar of many pliers is relatively long, and it often slips when the personnel operate, which affects the processing of the operator. At present, there are some needle-nose pliers. The pliers mouth is particularly easy to wear during use, which shortens the service life of the needle-nose pliers and reduces the use effect of the needle-nose pliers
