Description

[0002] In the power construction site, when planning the installation of the cable, the conductor needs to be pulled and moved, and the laying of the cable is mostly completed by manual work. The cable itself is heavy, and the whole outside is wrapped with a thick insulating layer. Workers mostly drag the cable with their hands to complete the work. When the length of the cable is long, the resistance generated during the dragging process is large. The outer layer of the cable is provided with an insulating layer, so the outer layer is relatively smooth, and it is difficult for workers to hold the cable for a long time to work. But the existing traction work can also rely on a motor vehicle to work. The cable is fixed to the tail of the motor vehicle through a clamp type clamping connector, and then the cable is moved by using the motor vehicle. First of all, the locking structure fixed to the tail of the motor vehicle is relatively simple. Although it is practical and convenient, it will still be loose or directly fall off under the pulling, and the locking part is prone to cable skin deformation. The clamping effect of the cable is poor.
