Portable secondary cable stripping knife

Abstract

The invention provides a portable secondary cable stripping knife, which comprises a lever A and a lever B. The portable secondary cable stripping knife is characterized in that: the lever A is composed of a working part A, a handheld part A and a hinge part A, the lever B is composed of a working part B (21), a handheld part B (22) and a hinge part B (23), the middle of the hinge part B is hinged to the middle of the hinge part A through a pin shaft, a vertically upward tool bit A is arranged at the left end of the upper surface of the working part A, a positioning groove with a downward opening is formed in the left end of the lower surface of the working part B, and the axis of the positioning groove is parallel to the axis of the pin shaft; and a rotatable guide wheel A is arranged in the middle of one side face of the handheld part A, and a tool bit B is arranged on one side of the guide wheel A. According to the invention, girdling and side cutting of the sheath of the secondary cable can be rapidly realized, the process is safe and stable, the efficiency is high, and the portable secondary cable stripping knife has the advantages of convenience in carrying, simplicity in operation and adaptability to conventional secondary cables with different wire diameters.

Description

technical field [0001] The invention relates to electric power construction tools, in particular to a portable secondary cable stripping knife. Background technique [0002] The primary cable refers to the power cable, that is, the cable that provides power for electrical equipment, and its wire diameter is relatively large. In the prior art, there are many cable stripping tools for primary cables or large wire diameters, such as: 10KV, 35KV cable heads To make tools, such tools mostly adopt the method of gradually stripping around, and the tools are bulky and difficult to carry, and the efficiency is low. [0003] Secondary cables refer to cables used for control, signal transmission, and feedback, and their wire diameters are generally small, so the above-mentioned tools for primary cables are not applicable. [0004] After laying out the secondary cables of new or renovated substations, it is necessary to peel off part of the secondary cable sheath for wiring. Usually, t...

[0003] The secondary cable refers to the cable used for control, signal transmission and feedback, and its wire diameter is generally small, and the above-mentioned tools for the primary cable are not applicable

[0004] After laying out the secondary cables of new or renovated substations, it is necessary to peel off part of the secondary cable sheath for wiring. Usually, three to four layers of secondary cables need to be stripped to expose the cable core. At present, the working method of stripping is to use The paper cutter slowly cuts and peels off, the work efficiency is low, and a little carelessness can easily damage the insulation layer inside the cable, and even cause personal injury
