Description

a wire stripper

technical field

The invention relates to a wire stripper.

Background technique

A common wire stripper in the prior art includes two pliers handles, and each pliers handle includes a jaw section at one end, a handle section at the other end, and a hinge section between the jaw section and the handle section. The hinges are hinged by pin shafts, and the jaws of the two pliers handles are provided with jaws. By putting the cable into the jaws, and then holding the two pliers handles tightly, the cable skin is broken at the jaws, and Peel off the cable skin that needs to be stripped from the wires to expose the wires. This type of wire stripper often needs to master a certain grip force during use to ensure that the cable skin is stripped off without damaging the wire; secondly, this type of wire stripper can only achieve radial stripping of the wire, but cannot achieve Longitudinal stripping and cutting; Again, for cables with larger diameters and harder materials, this type of wire stripper often does not have jaws suitable for large-diameter cables, and the stripping force provided by holding two pliers handles is not suitable for such cables. The stripping of hard cables is not strong enough; finally, this type of wire stripper is easy to fall off due to improper operation or not being held firmly by the operator during use.
