[0023] A second motor 8 is fixedly connected to the bottom of the mobile trolley 2, and a driving sprocket 9 is fixedly connected to the output end of the second motor 8. A reducer is connected to the output end of the second motor 8, and the output end of the reducer is fixedly connected to the driving sprocket 9. The bottom of the mobile trolley 2 is rotatably connected to two driven sprockets 11. The outer walls of the driving sprocket 9 and the two driven sprockets 11 are jointly sleeved with a second chain 10. The outer wall of the second chain 10 is fixedly connected to a first fixed block 12. The first fixed block 12 is fixedly connected to a first telescopic plate 13. The first telescopic plate 13 is slidably connected to the mobile trolley 2, and the first telescopic plate 13 can be driven to move by the second motor 8.

[0024] The first telescopic plate 13 is slidably connected to the second telescopic plate 14, and a synchronization mechanism is provided on the front and rear sides of the first telescopic plate 13. The synchronization mechanism includes two rotating sprockets 15 rotatably connected to the side walls of the first telescopic plate 13, and the two rotating sprockets 15 are jointly sleeved with a rotating chain 16. The outer wall of the rotating chain 16 is fixedly connected to a second fixed block 17, and the lower side of the rotating chain 16 is fixedly connected to the second fixed block 17.
