Background

Pliers, also called wire pliers, are hand tools, the jaw has a blade, is used for pulling nails or cutting nails and iron wires, it is a kind of pliers and shearing tool, it belongs to the labor-saving lever, the pliers are many kinds, its use is very wide, it is a kind of hand tool for clamping and shearing work piece that is indispensable in the work of assembling, repairing and installing in various industries. However, it has a common basic structure, namely that any hand pliers is composed of three parts, namely a pliers head, a pin and a pliers handle. The basic principle of the pliers is that two levers are crossed and connected together by a pin at a point in the middle part, so that two ends can move relatively, and an object can be pinched at the other end only by operating the tail end by hands. In order to reduce the effort of a user in operation, according to the lever principle in mechanics, the handle of the pliers is usually longer than the head of the pliers, so that a stronger clamping force can be obtained with a smaller force to meet the use requirement, and therefore, the pliers are used by operation workers such as electricians and the like.

However, the conventional common vice is simple in structure and has clamping and shearing functions, but shearing force is not easy to grasp, and an electrician is generally used for stripping wires when using the vice, but the conventional vice stripping is completely felt by experience, so that a person just engaged in the industry often excessively cuts off a plurality of wires or damages the wires, the condition of poor contact after later wiring is possibly caused, and most of pliers are discarded and replaced by new pliers after the shearing port is passivated, so that resource waste is caused.
