In this process, the two passive wheels 11 are driven by the elastic rod 7 to rotate on the frame rod 12, so that the elastic rod 7 quickly passes through the guard. When the elastic rod 7 completely passes through the guard, the cable is tied to the elastic rod 7 by the wire binding part, and the active wheel 6 is driven to rotate in the opposite direction by the motor 20. Under the cooperation of the passive wheel 11, the elastic rod 7 quickly drives the elastic rod 7 to move in the opposite direction and exit the guard, and the elastic rod 7 drives the cable to quickly pass through the guard, and the threading operation is convenient and efficient.
