The No. 1 turning handle 14 facilitates the staff to rotate the No. 3 adjusting threaded rod 13, and then adjust the height of the positioning block 15. After the angle adjustment of the battery pack is completed, the positioning block 15 is tightly fitted to the No. 1 support plate 5, thereby preventing the No. 2 support plate 8 from rotating, thereby ensuring the stability of the battery pack during replacement. Then, the No. 1 turning handle 408 facilitates the staff to rotate the No. 1 adjusting threaded rod 407, and then the No. 2 turning rod 409 moves on the outer wall of the No. 1 adjusting threaded rod 407, thereby changing the angle between the No. 1 hinged rod 403 and the No. 2 hinged rod 404, thereby lifting the height of the No. 1 support plate 5, so that the battery pack can penetrate into the battery slot on the belly of the new energy vehicle. Finally, the No. 2 turning handle 412 facilitates the staff to rotate the No. 2 adjusting threaded rod 411, and then adjust the height of the fixing block 413, so that when the battery pack is inserted into the battery slot on the belly of the new energy vehicle and is ready to be tightened, the No. 1 adjusting threaded rod 407 can be locked to ensure that the height of the No. 1 support plate 5 does not change, thereby ensuring the stability of the battery pack during replacement.
