[0023] By installing a rotatable limiting member in the mounting hole 202 on the winch 2, a single strand of cable is passed through the limiting member and then converged into the cable bundle unit. By rotating the winch 2, each single wire or insulated core is twisted together according to a certain rule and direction. During the twisting process, the sliding friction is changed to rolling friction by the setting of the limiting member, which effectively reduces the damage or scratches to the cable caused by friction.
