[0048] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0049] The working principle of the present invention is as follows: first, hold the pull bar 478 on the right side and pull it forward, so that it drives the buckle rod 477 to overcome the elastic force of the spring rod 476 and allow the buckle rod 477 to move forward, then insert the mounting bar 472 into the inner wall of the mounting seat 471, loosen the pull bar 478, allow the buckle rod 477 to be rebounded back to its original position by the elastic force of the spring rod 476, so that the buckle rod 477 is inserted into the inner wall of the mounting bar 472 and clamps the mounting bar 472, so as to realize the fast installation of the right-side snap ring sleeve 473 on the mounting seat 471 through the mounting bar 472, continue this operation to install the left-side snap ring sleeve 473, install both snap ring sleeves 473, and then start the second motor 71, let it drive the first sprocket 73 to rotate through the output shaft, and when the first sprocket 73 rotates, it drives the second sprocket 74 through the transmission chain 75, so that the second sprocket 74 rotates on the back plate 1 through the rotating shaft 72 When the transmission chain 75 moves, it drives the fixed seat 2 to make the fixed seat 2 slide on the surface of the sliding column 10 through the sliding sleeve 3 to adjust the height position of the fixed seat 2 and all the structures on its front side, so that the two snap ring sleeves 473 are adjusted to the patient's waist position, and then the patient is allowed to stand between the two snap ring sleeves 473, and then the first motor 41 is started to drive the rotating disk 43 to rotate through the output shaft.
