[0001] The present application relates to the technical field of cable pulling device, in particular to a variable-diameter multi-cable synchronous winding method. BACKGROUND

[0002] Cables are electrical products used for transmitting electrical energy, transmitting signals, and converting electromagnetic energy. The basic structure of a cable usually includes a conductor, an insulating layer, a filler layer, a shielding layer, and a sheath. The conductor is the core part of the cable, responsible for transmitting electrical energy or signals. The insulating layer is used to isolate the conductor to prevent current leakage and short circuits. The filler layer enhances the mechanical properties of the cable. The shielding layer reduces electromagnetic interference and signal loss. The sheath protects the cable from the external environment.

[0003] During the installation and laying of the cable, a pulling device is needed to assist the staff in pulling the cable. The existing pulling device can fix the cable well, preventing it from falling off.
