[0002] With the continuous development of society, the use of electricity plays an important role in people's lives, and cables are an important medium for power transmission. During the cable processing, it is necessary to cut the cables. A cable cutting device is a device specifically used for cutting cables or other wire materials.

[0003] Chinese Patent with application number CN202321258468.1 discloses a power cable cutting device, which relates to the technical field of cable processing. It includes a workbench. A cable placement groove is opened at the top of the workbench. An L-shaped motor base is installed at the bottom of the workbench. A driving motor is fixedly provided on the L-shaped motor base. Two installation rotation holes are opened at the top of the workbench. Lifting screw columns are rotatably installed in both of the two installation rotation holes. The output end of the driving motor is connected to the bottom end of one of the lifting screw columns. A support plate is commonly threadedly sleeved on the two lifting screw columns.
