During the laying process of the cable, tools are needed to cut the cable manually. The manual cutting of the cable requires the cooperation of multiple people, which not only increases the labor intensity and reduces the production efficiency, but also wastes labor and cannot maintain the stability of the cutting. When cutting thick cables, the cables may sway, which may pose a risk to the operator. Moreover, the smoothness of the cable break and the chamfer cannot be guaranteed, which may lead to the failure of the cable and the cable connector to tightly overlap, leaving a safety hazard.
