[0043] Specific usage of this utility model:

[0044] First, adjust the extension and contraction of the second telescopic rod 51, insert the bolts 17 at both ends into the two adjacent flange ring holes 21 of the flange ring 12 respectively, and start the hydraulic device 14. The hydraulic device 14 will make the tower 11 rise, and release the pull rod 40 while rising. The second sliding rod 48 pops outward under the action of the sixth spring 52, and the first swing arm 43 and the fixed block 49 are not in contact. The first swing arm 43 swings outward through the action of the fifth spring 44, and the first swing arm 43 contacts the inner wall of the tower 11. The swing of the first swing arm 43 drives the second swing arm 47 to move, and the movement of the second swing arm 47 drives the sliding of the fifth slider 46. The sliding of the fifth slider 46 drives the sliding of the fourth slider 38. The sliding of the fourth slider 38 drives the fourth spring 39 to move, and the fourth spring 39 pulls the third slider 37 to slide. When the two first swing arms 43 have the same swing amplitude, the third slider 37 will slide to the middle position, and the center of the tower 11 and the flange ring 12 are aligned. The center of the circle coincides with each other, and at the same time, the inner wall of the tower 11 and the inner wall of the flange ring 12 coincide with each other. The second spring 33 in the fourth cavity 32 will pop out the second slider 35 in the direction of the third slider 37. The second slider 35 is connected to the third spring 36. The first slider 29 pops out under the action of the third spring 36. The first slider 29 is embedded in the groove of the third slider 37. At the same time, due to the action of the connecting column 28, the first slider 29 is fixed to the center of the circle of the tower 11. An elastic plate 27 is provided on the first slider 29. When the first slider 29 is embedded in the groove of the third slider 37, the elastic plate 27 will contact the wall of the second cavity 25. The protruding teeth on the elastic plate 27 engage with the recessed grooves on the inner wall of the second cavity 25, thereby limiting the displacement of the first slider 29, thereby limiting the angle of the first rocker arm 43, so that the inner wall of the tower 11 is aligned with the inner ring of the flange ring 12, while preventing the elastic plate 27 from deforming, and the elastic support rod 31 will support the elastic plate 27.
