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

Embodiment 1

[0031] Such as Figure 1-2 As shown, the cable stripping knife includes a handle 1 and a blade 2. One end of the handle 1 is provided with a cutter head 3. The cutter head 3 and the handle 1 are integrally formed. The cutter head 3 is provided with a blade 2 Groove 31, cutting support portion 32, locking block 33 and locking bolt 34, cutting support portion 32 is located at the opposite end of the cutter head 3 connected to the handle 1, the groove 31 runs through the cutting support portion 32, The blade 2 is placed in the groove 31, the blade 2 protrudes from the through side of the groove 31 and the distance between the blade 21 of the blade 2 and the cutting support portion 32 is slightly smaller than the thickness of the cable to be stripped, so as to ensure that the cross-cutting blade 212 will not cut Wear the cable sheath and damage the internal structure of the cable, the locking block 33 is pressed on the blade 2, and the bottom of the groove 31, the locking block 33...

Embodiment 2

[0039] On the basis of the technical scheme of embodiment 1 cable stripping knife, have carried out following improvement:

[0040] Such as Figure 3-4 As shown, one end of the cutting support portion 32 is also provided with a multi-function bump 38, and one end of the blade 21 intersects with one side of the multi-function bump 38 to form a slitter tip 211 for longitudinal cutting of the cable sheath. This side of the bump 38 is the slitting support portion 381, the distance between the top of the slitting knife tip 211 and the slitting support portion 381 is slightly smaller than the thickness of the cable sheath to be stripped, and the blade 21 intersects with the other side of the multifunctional bump 38 Form the cross-cutting blade 212 for the transverse cutting of the cable sheath, and this side of the multifunctional projection 38 is a cross-cutting auxiliary support portion 382; the auxiliary support block cooperates with the cutting support portion 32 to form a struc...

Abstract

The invention discloses a cable skinning knife, comprising a knife handle and a knife blade. A knife head is arranged at one end of the knife handle. The knife head and the knife handle are two independent structures which are fixedly connected, or an integrally formed whole structure. A groove for mounting the knife blade, a cut support part, a locking block and a locking bolt are arranged on the knife head. The cut support part is located on the knife head at the other end opposite to the end connected with the knife handle. The groove penetrates the cut support part. The knife blade is arranged in the groove. The knife blade stretches out of the penetration side of the groove. The distance between the edge of the knife blade and the cut support part is a little less than the thickness of a to-be-skinned cable sheath. The locking block is pressed on the knife blade. The locking block, the knife blade and the knife head are locked through locking bolt. According to the cable skinning knife, the knife blade is mounted stably and the blade can be assembled, disassembled and replaced conveniently. The cable skinning knife is applicable to cables of different diameters. The skinning depth is uniform. The cable skinning knife has the advantages of simple structure, simple and convenient operation, security, reliability and high skinning efficiency.

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 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 insulating layer inside when cutting. Contents of the invention [0003] In order to overcome the above existing problems in the prior art, one of the tasks of t...
