A cable cover-peeling knife

Abstract

The present invention relates to the field of cable knives, in particular to a cable cover-peeling knife which comprises a first knife rest, a second knife rest and an adjusting screw. One side of the second knife rest is provided with a guide straight groove; one side of the first knife rest is provided with a guide block which is embedded in the guide straight groove and capable of reciprocating movement; the adjusting screw goes through the guide straight groove to be in threaded connection with a guide block; both ends of the adjusting screw are respectively rotatably connected to the both ends of the guide straight groove; the first knife rest and the second knife rest are correspondingly provided with a first clamping surface and a second clamping surface; the first knife rest or the second knife rest is fixedly equipped with a chamfering blade; a chamfering cutting blade of the chamfering blade extends outside of the corresponding clamping surface; and an obtuse angle forms between the chamfering cutting blade and the corresponding clamping surface. The beneficial effects of the cable cover-peeling knife of the present invention are that the cable cover-peeling efficiency is high; the cover-peeling depth and angle are uniform; the cable internal structure can be effectively from being damaged in peeling; the cable cover-peeling knife is applicable to cables with different diameters; the universality is high; and the cable cover-peeling knife has a simple structure, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of cable cutters, in particular to a cable stripping knife. Background technique [0002] When installing or overhauling power cables, it is necessary to peel off the cable sheath (including insulating layer, semi-conductive layer, copper shielding layer, outer sheath, etc.) to connect the line. Traditional cable stripping tools use electrician's knife, hook knife or Tools such as wallpaper knives are used to peel the skin, but because the blades of these knives are not installed firmly, they are easy to shake when cutting the cable skin, and the depth of the cut cable skin is uneven, especially when cutting the semi-conductive layer or copper shielding layer of the cable, due to the semi-conductive Layer and copper shielding layer are relatively thin, it is easy to penetrate the semi-conductive layer or copper shielding layer and destroy its internal structure when cutting, and because the copper shielding layer is r...

And there are certain security risks
