Protection cable skinning knife

Abstract

The invention provides a protection cable skinning knife which comprises a handheld cylinder. A tightening mechanism is arranged on the upper end of the cylinder. The tightening mechanism comprises a ring with an internal thread and a tightening cylinder with an external thread. The ring sleeves the tightening cylinder, and is in matching connection with the tightening cylinder through the internal thread and the external thread. The tightening cylinder is composed of a number of tensioning bars, and extends outward along the upper end of the cylinder to form a cone with tapering bore. The axes of the tightening cylinder and the cylinder are superimposed. Two rod-shaped tools are symmetrically arranged on the upper end of the tightening cylinder, and a tool tip is arranged on the upper end of each tool. A tool rod is arranged on the lower end of each tool. The tool rods and the tensioning bars are hinged. An arc-shaped part is arranged on the front end of each tool tip. An arc-shaped notch with an outward opening is arranged below each arc-shaped part. An arc-shaped blade is formed on the inner side of the upper part of each arc-shaped notch. The arc-shaped blades of two tools are inwardly corresponding. According to the invention, a cable skinning effect is improved; skinning time can be greatly reduced; when skinning is carried out, a cable core wire can be effectively protected from being scratched; the whole protection cable skinning knife sleeves a cable; and the protection cable skinning knife has the advantages of easy use and time and effort saving.

Description

technical field [0001] The invention relates to a cable stripping tool, which belongs to auxiliary tools for electric power construction, in particular to a protective cable stripping knife. Background technique [0002] In the construction of electric power and electrical engineering, it is often necessary to connect cables with switches, controllers and other power components to achieve power or signal communication. Regardless of the size of the cables, the conductive cores are covered with an insulating protective layer, usually small Cables can be stripped with wire strippers or pliers, but for larger diameter power cables, pliers cannot be used to strip the insulation. In actual construction, wallpaper cutters are often used, which is more efficient. Low and easy to scratch the conductive core wire. Existing large-diameter power line stripping tools on the market have higher cost, larger volume and weight, and are inconvenient to carry and use. [0003] Chinese paten...

AI Technical Summary

Problems solved by technology

However, because the hook of the arc-shaped cutter head protrudes outwards and the cutting depth of the arc-shaped blade cannot be controlled, it is still easy to damage the cable core wire during the cable stripping and stripping process; when using it, it needs to be held or fixed It is inconvenient to strip the cable after the cable is locked; in addition, one use can only form a knife edge on the cable insulation layer, and the thicker cable insulation layer will still be tightly wrapped around the cable core wire, and it will take time and effort to separate the two. Reduced efficiency of cable stripping
