[0010] Among them, the retractable wheel is rotatably installed on the traction trolley. When the cable is laid and retracted, it passes between the two retractable wheels, ensuring the smoothness of the cable passing through the traction trolley when retracted and released, and avoiding scratches or entanglement between the cable and the traction trolley when the cable moves with the traction trolley.

[0011] As a preferred technical solution, the retractable rack is provided with a walking groove, the traction trolley is provided with a traction frame, the lower end of the traction frame is provided with a walking wheel, and the walking wheel is arranged in the walking groove. The traction trolley moves along the walking groove,

[0023] The submarine cable active retraction arm of this embodiment includes a cable tray 1. A drive motor 6 is fixed to the bottom of the cable tray 1. During cable retraction and release operations, the drive motor 6 is used to drive the cable tray 1 to rotate. A support frame 2 is fixedly mounted at the center of the cable tray 1. A retraction and release frame 5 is fixed to the support frame 2. The retraction and release frame 5 is mounted on the axis of the cable tray 1. A traction trolley 3 is mounted on the retraction and release frame 5. The traction trolley 3 moves laterally along the retraction and release frame 5. During retraction and release operations, the cable 4 moves with the traction trolley 3, achieving orderly retraction and release of the cable 4.
