The first outer ring 4 and the first inner ring 5 are both arranged at the upper end center of the lower unloading seat 1. The diameter of the first inner ring 5 is smaller than the diameter of the first outer ring 4. The second outer ring 6 and the second inner ring 7 are both arranged at the lower end center of the upper unloading seat 2. The diameter of the second inner ring 7 is smaller than the diameter of the second outer ring 6. The diameter of the first outer ring 4 is equal to the diameter of the second outer ring 6. The diameter of the first inner ring 5 is equal to the diameter of the second inner ring 7. The heights of the first outer ring 4, the first inner ring 5, the second outer ring 6 and the second inner ring 7 are the same. The lower unloading seat 1 is fixedly connected with the support base 3 in advance. The upper unloading seat 2 can be used in combination with the lower unloading seat 1 by transportation. It is a movable assembly. The lower unloading seat 1 and the support base 3 are detachable assemblies, which are convenient for later transportation and use.

[0035] The upper ends of the first outer ring 4, the first inner ring 5, the second outer ring 6 and the second inner ring 7 are all provided with spiral contact surfaces, the spiral directions of the spiral contact surfaces of the first outer ring 4 and the first inner ring 5 are oppositely arranged, and the spiral directions of the spiral contact surfaces of the second outer ring 6 and the second inner ring 7 are oppositely arranged.

The constraint plate 21 is plugged into one side of the holding mounting seat 17. Four scale plates 16 are respectively movably inserted through the holding mounting seat 17. The holding mounting seat 17 is provided on the side of the lower unloading seat 1 close to the first outer ring 4. One side of the holding mounting seat 17 vertically penetrates the lower unloading seat 1 and is provided with a guide slot 18. The lower ends of the four scale plates 16 are respectively movably inserted into the guide slots 18 of the four holding mounting seats 17. The four scale plates 16 are respectively plugged into the four holding mounting seats 17. The holding mounting seat 17 can improve the external support strength of the first outer ring 4, and the rotating ring 14 can improve the external deformation support strength of the second outer ring 6.

[0040] A connecting groove 19 is provided on the side of the retaining mounting seat 17 away from the first outer ring 4 and the scale plate 16, and a support shaft 20 is horizontally provided in the connecting groove 19. One side of the constraint plate 21 is movably sleeved on the support shaft 20. One side of the retaining mounting seat 17 is connected to the guide slot 18, and abutment protrusion 22 is provided on one side of the constraint plate 21. When the constraint plate 21 is horizontally set, one side of the abutment protrusion 22 is plugged into the guide slot 18 and abuts against the scale plate 16. A spring groove 23 is horizontally provided on the side of the constraint plate 21 away from the support shaft 20, and a positioning pin 24 is horizontally plugged in the spring groove 23. One side of the positioning pin 24 movably penetrates the constraint plate 21. A cross positioning groove 25 is provided on the side of the support shaft 20 close to the positioning pin 24. One side of the positioning pin 24 movably penetrates the spring groove 23 and is plugged into the cross positioning groove 25. The positioning pin 24 is located in the spring groove 23 and is provided on the side close to the support shaft 20. The locating pin 24 is inserted into the horizontal section of the cross positioning groove 25 to keep the position of the constraint plate 21 stable. Since the scale plate 16 is in close contact with the upper and lower seats 2 through the rotating ring 14, when the scale plate 16 cannot be lowered or raised, the upper and lower seats 2 maintain their position, which improves the convenience of use. In addition, the number of scale plates 16 can be adjusted according to the weight of the upper and lower seats 2 to ensure that the upper and lower seats 2 maintain a stable height before losing human support and the main body of the building contacts it.
