Embodiment 1

[0020] For the preheating type cable stripping knife of this embodiment, refer to the attached Figure 1-4 , including fixed handle 1, upper sipe 2 and lower sipe 3. Wherein, the outer side of the upper sipe 2 and the lower sipe 3 is U-shaped, and the inner side is a V-shaped groove. The upper sipe 2 and the lower sipe 3 are respectively inverted U-shaped and positive U-shaped. Put it into the circular area formed by the fastening of the V-groove on the inner side of the upper and lower sipes.

[0021] The lower part of the U-shaped end of the upper sipe 2 is connected to the U-shaped end of the lower sipe 3 through the movable part 22. The upper and lower handles are movably connected by long bolts, and the upper and lower handles use long bolts as shafts to realize the opening and closing of the upper and lower sipes, and the fixed handle 1 is fixed on the outside of the movable part 22 at the same time.

[0022] The other ends of the U shape of the upper slit 2 and the lo...

Abstract

The invention relates to a preheating cable skinning knife. The preheating cable skinning knife comprises a fixed handle, an upper cutter groove and a lower cutter groove, wherein a T-shaped cutter placing opening is arranged at a U-shaped top of the upper cutter groove, a cutter is arranged in the cutter placing opening and comprises a T-shaped fixed table, a blade and a telescopic element, the blade is arranged at a tail end of a T-shaped vertical line, the telescopic element can elastically stretch to and contract from a side part of a T-shaped horizontal line, sliding grooves are formed in V-shaped grooves of the upper cutter groove and the lower cutter groove, rolling balls are arranged in the sliding grooves, and a heating device is arranged at the bottoms of the sliding grooves and is used for heating the rolling balls. The preheating cable skinning knife can be used for preheating and processing a hard outer skin of a cable, a cutter bit and the cable axially and vertically apply forces after the hard outer skin is soften, annular cutting of the outer skin of the cable is achieved, the cutter is rotated by 90 degrees to longitudinally cut the skin, the preheating cable skinning knife is simple to operate, the working difficulty is reduced, the working safety is also improved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an electric power tool, in particular to a preheating type cable stripping knife. Background technique [0002] During the construction, maintenance and intelligent upgrading of substations, it is necessary to rewire various old wires and cables, or directly relay new cables. Whether rewiring old cables or re-routing new cables, the cable ends need to be stripped to allow for distribution and connection of the cable cores. [0003] When stripping the cable sheath, a stripping knife or stripper is required. The peeling tools currently used mainly include electrician's knife, hook knife and wallpaper knife. The shortcomings of the above three tools mainly contain the following points: 1. The use process is not safe. Due to the smooth surface of the cable, it is easy to slip when peeling. Construction workers often cut their hands or cut their work clothes during the operation, and there are even bloody incidents of cutting ot...
