Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary equipment for power supply line maintenance, and more particularly to a cable cutting device for line maintenance. Background Art

[0002] After the power supply line is fused, it needs to be repaired. During the maintenance, the line will be cut, and then the cut ends of the line will be fixed together with insulating tape. When cutting the line, the staff generally uses scissors or other tools to cut the line. After cutting, the cut end of the line will have a flat cut under the action of pressure, and the two ends of the cut will extend outwards to form sharp tips. The shape of the cut part is similar to an inclined shovel. When winding the two ends of the line together, the sharp tips at the cut part are very likely to pierce the insulating tape, and more insulating tape is needed for fixation, wasting resources.
