A driving gear 23 is connected to the inner surface of the turntable 17. A second transmission gear 25 is provided on the upper surface of the driving gear 23, and a first transmission gear 24 is provided on the lower surface of the driving gear 23. The staff manually rotates the turntable 17 to drive the internally connected driving gear 23 to rotate, so that the rotating driving gear 23 can drive the first transmission gear 24 and the second transmission gear 25 that are meshed with each other up and down to rotate, and then the rotating first transmission gear 24 and the second transmission gear 25 can drive the connected threaded rod 27 to rotate. The rotating threaded rod 27 can drive the threaded sleeve shaft 26 on the surface to cooperate and move up and down, so that the threaded rod has adaptability and stability.

A connecting piece 19 is fixedly installed on one side surface of the bottom shaft rod 18, and a bottom pin rod 20 is connected to the lower surface of the connecting piece 19. By fixing the bottom shaft rod 18 on both sides of the silk sleeve shaft 26, it can be moved up and down together with the silk sleeve shaft 26, thereby driving the connecting piece 19 fixedly installed on one side surface of the bottom shaft rod 18 to move together, and then the bottom pin rod 20 connected below it can be moved up and down together to adjust the position of the bottom pin rod 20, and it can be matched with the mounting block 22 above to penetrate and connect to fix and protect the door panel body 10, making it adjustable and practical.

[0038] Reference Figure 1-5 A mounting block 22 is mounted on the outer surface of the bottom pin rod 20. A socket 21 is formed in the center of the mounting block 22. A sealing plug 28 is connected to one side of the bottom pin rod 20. A return spring 29 is provided on the upper surface of the sealing plug 28. A mounting bracket 30 is mounted on the outer surface of the return spring 29. The mounting block 22 allows the socket 21 to function as a limiter and fixator during movement.
