Description

Cutting tool for testing thickness of wire and cable insulating layer

Technical Field

The utility model relates to the technical field of cutting tools, in particular to a cutting tool for testing the thickness of an insulating layer of a wire and a cable.

Background

In a wire and cable detection test, the thickness and the overall dimension of a wire and cable insulation layer material are required to be detected, and the existing method comprises the following steps:

1. after wires and cables with small pipe diameters are pulled out of an inner element (generally a copper wire), the wires and cables need to be fixed by one hand, and a blade is held by the other hand to directly cut the cross section of the wires and cables in the radial direction to obtain an insulating layer thin sheet as thin as possible, so that the method has the following defects:
