When the guide inclined plate 2 is tilted and turned over, the guide inclined plate 2 can pull the limiting traction rope 24, so that the spring stores energy. The winding shaft 241 limits the guide inclined plate 2 through the limiting traction rope 24, prevents the guide inclined plate 2 from tilting too much, and when the battery pack is lowered, the guide inclined plate 2 becomes vertical. At this time, the winding shaft 241 completes self-rotation under the driving of the elastic restoring force of the spring, so that the winding shaft 241 winds the limiting traction rope 24, avoiding the interference of the limiting traction rope 24 to the turning over of the guide inclined plate 2.

[0042] It needs to be explained that the lower connecting box 13 described in this embodiment is in space butt joint with the first groove 12, and the lower connecting box 13 has two insertion grooves which are in butt joint with the guide sliding rods 31.

[0043] Specifically, the two guide sliding rods 31 are adjusted in height when the lifting plate 3 is lifted, so that the lower connecting box 13 can guide the lifting plate 3 through the guide sliding rods 31, so that the lifting plate 3 can be stably limited, the fourth groove 131 accommodates the compression spring 32, so that the lifting plate 3 can be lowered into the first groove 12, and the compression spring 32 pushes the lifting plate 3, so that the lifting plate 3 can push the battery pack upwardly when the compression is finished.
