During operation, the motor 40 drives the crank 50 to rotate, causing the slider 30 to perform a reciprocating circular motion back and forth. Then, the slider 30 controls the hook 60 to swing left and right. The hook 60 is used to hook the battery, and the hook 60 swings back and forth to unlock or lock the battery. When the user only needs to insert the battery into the battery compartment, after the battery is inserted, under the action of the spring 70, the hook portion 61 of the hook 60 automatically hooks the battery. When the battery is hooked, the trigger piece 82 is touched, and then the trigger piece 82 touches the detection sensor 81 to transmit a signal that the battery is hooked to the external control system. When it is necessary to eject the battery, the external control system controls and drives the motor 40. The motor 40 drives the crank 50 to rotate, causing the slider 30 to move forward, so that the hook portion 61 of the hook 60 is disengaged from the battery, and the trigger piece 82 is released to achieve the unlocking function. When the slider 30 reaches the position, the control system receives the ejection signal and stops power supply. When the control system detects that the battery is removed, the control system controls the motor 40 to drive the slider 30 to retract, and stops power supply when detecting the signal of returning to the in-place position.
