[0044] When it is necessary to disengage the connector 62 from the linkage slot 31, the motor 71 starts, driving the second gear 72 to rotate counterclockwise. The counterclockwise rotation of the second gear 72 drives the first gear 551 and the threaded rod 552 to rotate clockwise. The clockwise rotation of the threaded rod 552 drives the sliding block 53 to slide towards the battery 4. The sliding block 53 drives the push block 53 and the linkage block 6 to slide until the connector 62 is disengaged from the linkage slot 31. At this time, the motor is turned off, and the handle 1 is in an idle state.
