The wire stripping pliers are composed of a knife edge, a wire pressing port, and a pliers handle. Speaking of the mechanism principle of the wire stripping pliers, the wire stripping pliers belong to a typical variable degree of freedom mechanism, and their design principle is the minimum torque method. That is to say, there are several springs of different sizes inside the wire stripping pliers, which achieve sequential movement as the gripping force continues to increase.
When gripping the handle of the wire stripper to work, the spring is first compressed, causing the clamping mechanism to clamp the wire. At this point, due to the action of torsion spring 1, the shear mechanism will not move. When the clamping mechanism fully clamps the wire, the force acting on torsion spring 1 gradually increases, causing torsion spring 1 to begin to deform and causing the shear mechanism to start working.
At this point, the force exerted by torsion spring 2 is not enough to separate the clamping mechanism from the shear mechanism. After the shear mechanism completely cuts the wire skin, the shear mechanism is clamped. At this point, the force exerted on torsion spring 2 increases. When the force exerted on torsion spring 2 reaches a certain level, torsion spring 2 begins to deform, and the clamping mechanism and shear mechanism separate, causing the insulation skin of the cut wire to separate from the wire, thus achieving the purpose of wire stripping.
