Only need to place the battery pack in the protective frame, and then use an external device to start the rotating motor. The rotating motor drives the first rotating rod to rotate. The rotating first rotating rod controls the two shovel plates to approach each other, so that the battery pack can be shoveled up. When the lifting frame rises to a certain height, the gear of the adjustment frame meshes with the toothed plate. As the lifting frame continues to rise, the gear rotates under the action of the toothed plate. At this time, the second rotating rod rotates, and the rotating second rotating rod can clamp the battery pack on the shovel plate to the middle position. And when the rotating motor controls the two shovel plates to move away from each other, the battery pack can always be located in the middle position until the battery pack drops after the shovel plate moves a certain distance.
