The cable is used to transmit and distribute electric energy, and is commonly used in the urban underground power grid and the internal power supply of industrial and mining enterprises. The cable needs to be laid to realize the supply of urban electricity and enterprise electricity. Cable laying refers to the wiring method of the cable from the distribution box to the electrical equipment or another distribution box; for example, laying along the ground, along the wall, along the ceiling in a concealed manner, in an exposed manner, through a cable tray, through a cable trench, through a cable trough, etc. are all common cable laying methods. Traction means pulling the cable out from the cable reel, and generally, a cable laying traction device is required to pull and lay the cable.

The movement of the sliders 2322 can drive the two tensioning plates 233 to move radially on the roller 231, thereby being able to push the tensioning plate 233 to move.

[0045] Refer to Figures 1 to 3 , in some embodiments, a rotatable handle 234 is provided at the suspended end of the roller 231. The handle 234 is generally circular. One end of the handle 234 is connected to the end of the lead screw 2321.
