At the same time, the a1 docking connector is docked with the a2 docking connector, and the b1 docking connector is docked with the b2 docking connector. The anti-skid chain is transferred from the tire to the chain. After the first-order anti-skid chain is transferred from the tire to the chain, this step is repeated until several anti-skid chains are separated from the tire. S3-2, when all the a3 docking devices on the anti-skid chains are separated from the corresponding a4 docking devices and the b3 docking devices are separated from the corresponding b4 docking devices, the a4 docking device or b4 in the last position sends a reverse signal to the motor, and all the B5 movable levers gather at the core of the B4 chain disassembly gear again, and are recovered into the car body at the wheel position through the gear drive rack and the movable frame, completing the anti-skid chain disassembly and chain collection operations.
