in this embodiment, during normal use, as shown in fig. 1 and 2, the storage battery is placed on the lifting plate 3, when the storage battery needs to be taken out, the main shaft 4 is rotated to rotate the driving arm one 6 along with the rotation, because the lifting plate 3 can slide relative to the box body 2, the lifting plate 3 and the storage battery thereon can move upwards simultaneously, when the lifting plate 3 is at a higher position, the main shaft 4 stops rotating, and then the storage battery is taken out.

Further, one end of the main shaft 4 extends out of the box body 2, and a ratchet wheel 8 is fixed on the end;

a shell 9 covering the ratchet 8 is fixed on the box body 2, a sliding block 10 matched with the ratchet 8 slides on the shell 9, and one end of the sliding block 10, which is close to the ratchet 8, is provided with an inclined plane and a plane;

a return spring 11 for returning the slider 10 is sleeved on the slider 10, a support ring 12 is fixed on the slider 10, and two ends of the return spring 11 are respectively contacted with the support ring 12 and the inner wall of the shell 9;

in the embodiment, when the main shaft 4 rotates, the ratchet 8 is driven to rotate along with the main shaft, as shown in fig. 3, 5 and 7, when the main shaft 4 rotates counterclockwise, the lifting plate 3 and the like are driven to ascend, and in the process, the inclined surfaces of the teeth of the ratchet 8 are in sliding fit with the inclined surfaces on the sliding block 10, the sliding block 10 and the supporting ring 12 are driven to move, and the sliding block 10 and the like are reset under the action of the elastic force of the reset spring 11;

when the main shaft 4 stops, the end part of the teeth of the ratchet wheel 8 is in contact with the plane on the sliding block 10, and the sliding block 10 cannot be pushed to move, so that the main shaft 4 cannot rotate clockwise, and the position of the storage battery can be fixed when the main shaft 4 does not rotate, and the self-locking function is achieved.
