[0005] The above technical solution is further refined, the panel of the switch cabinet is a metal panel; an electromagnet is installed on the base, and is adsorbed on the panel of the switch cabinet through the electromagnet.

[0006] The above technical solution is further refined, and a plurality of positioning structures are distributed between the base and the panel of the switch cabinet; the positioning structures are composed of positioning protrusions and positioning holes.

[0007] The above technical solution is further refined. The smart crank also includes a battery pack, a controller, a motor current sensor, and a battery pack. The battery pack, controller, and motor current sensor are installed on a base and connected to form a control circuit. The control circuit is connected to the motor; the intelligent controller provides a stable current to the motor, so that the smart crank outputs a stable torque, ensuring that the process of switching in and out of the vehicle is safe and reliable; the change in motor current can be used to determine whether the smart crank has an abnormality. When the current increases, the crank stops working in protection mode.

[0008] The above technical solution is further refined, the tail end of the push rod extends out of the base, and a protective cap A is installed on the base. The protective cap A covers the tail end of the push rod and covers the push rod handle; the guide key handle extends out of the base, and a protective cap B is installed on the base, and the protective cap B covers the guide key handle.
