A kind of cable stripping knife and stripping method thereof

Abstract

The invention discloses a cable skinning knife and a skinning method thereof. The cable skinning knife comprises a knife handle and a knife blade, wherein a knife head is arranged at one end of the knife handle; a knife groove, a cutting supporting part, an auxiliary supporting block, a locking block, a locking groove and locking bolts are arranged on the knife head; the knife groove passes through two ends of the knife head, and is intersected with the cutting supporting part to form a knife seam; the knife blade is inserted from the penetrating side of the knife groove and a knife edge of the knife blade is stretched out from the knife seam to form a transverse cutting knife edge; the auxiliary supporting block is arranged on the knife head, and the auxiliary supporting block and the cutting supporting part form an inclined angle; one end of the knife blade is stretched out from the penetrating side of the knife groove to form a longitudinal cutting knife edge; the part, intersected with the longitudinal cutting knife edge, of the knife head form a longitudinal cutting supporting part; the locking groove is communicated with the knife groove; the locking block is placed in the locking groove and is pressed on the knife blade; and the locking block, the knife blade and the knife head are locked and fixed through the blocking bolts. According to the cable skinning knife, the knife blade is firmly installed, the skinning depth is uniform, the cable skinning knife has a transverse ring-cutting function and a longitudinal cutting function and is applicable for cables with different wire diameters, and the cable skinning knife is simple in structure, simple and convenient in operation, safe and reliable.

Description

Technical field [0001] The invention relates to the field of power tools, in particular to a cable stripping knife and a stripping method thereof. Background technique [0002] When installing or repairing power cables, it is necessary to peel off the cable sheath (including insulation layer, semi-conducting layer, copper shielding layer, outer sheath, etc.) to connect the line. Traditional cable stripping tools use electric knife, hook knife or Wallpaper knife and other tools are used for peeling, but because the blades of these knives are not stable, they are easy to shake when cutting the cable sheath, and the depth of the cutting cable sheath is uneven, which easily damages the internal structure of the cable, especially when cutting the semi-conductive layer of the cable. The semi-conducting layer is relatively thin, and it is easy to penetrate the semi-conducting layer during cutting to destroy the inner insulating layer. Summary of the invention [0003] In order to overco...

AI Technical Summary

Problems solved by technology

[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.) Tools such as wallpaper cutters can be used to peel the skin, but because the blades of these knives are not installed firmly, it is easy to shake when cutting the cable skin, and the depth of the cut cable skin is uneven, which is easy to damage the internal structure of the cable, especially when cutting the semi-conductive layer of the cable. The semiconducting layer is relatively thin, and it is easy to penetrate the semiconducting layer and destroy the internal insulating layer when cutting
