Description

Labor-saving wire stripper

Technical Field

The utility model relates to the technical field of wire stripping tools, in particular to a labor-saving wire stripper.

Background

The wire stripper is one of the common tools for internal wire electricians, motor repair and instrument electricians, and is used for stripping the surface insulation layers of the heads of the wires for the electricians, and can separate the insulation covers of the cut wires from the wires and prevent electric shock.

The existing common wire stripper is used for finding a wire stripping hole which is closest to the thickness of the wire but slightly smaller according to the specification of the wire to be stripped. The wire to be stripped is placed into the stripping hole, and the handle of the stripper is gently tightened to cut the knife edge of the stripper into the insulating layer on one side. The stripper is then slid along the insulation slowly along the length of the wire to cut and strip the insulation.

However, when the stripper is slid along the insulation along the length of the wire, this process is laborious due to the frictional resistance that may be created between the insulation and the wire.

New solutions are therefore required to address this problem.
