Description

Technical Field

[0001] The utility model relates to the technical field related to electric cable cutting devices, in particular to a power cable cutting device. Background Art

[0002] The electric cable cutting device is a cable cutting pliers that adopts electric mode. The current electric cable cutters are powered by two modes: lithium battery box and AC220V plug-in. The electric cable cutters include a handle device, a cutting device and a propulsion device. The propulsion device of the cutting pliers is driven by two gears to drive the movable knife body.

[0003] The existing electric cable cutting device uses a single blade for cutting on one side, while the other side remains fixed, which cannot assist in cable cutting. During long-term use, the electric cable cutting blade has many grooves, which affects the service life of the electric cable cutting blade. When the cable thickness exceeds 10mm, it exceeds the electric cable cutting thickness, so a large electric cable cutting device needs to be replaced. Utility Model Content

The cable cutter shrinks under the power of the power cable cutting device, and the slitting knife and the penetration head shrink and withdraw. After the power cable that exceeds the thickness is cut, it is electrically pushed and cut by the cable cutter. Therefore, when the power cable exceeds 10mm, there is no need to replace the large electric cable cutting device. It can be directly cut and separated after being cut by the slitting knife and the penetration head. BRIEF DESCRIPTION OF THE DRAWINGS
