[0027] When the body position support adjusting device is used, the patient puts his / her legs on the first support plate 5 and the second support plate 7, and fixes the legs by using the telescopic fixing belt 12. The user holds the rotating handle 1003 and rotates the threaded column 1002. While the first fixing plate 9 rotates, the hollow tube 1004 drives the first auxiliary rotating block 4 forward and pushes against the first auxiliary rotating block 4, so that the first support plate 5 is inclined upward, and the second support plate 7 is driven upward by the movable rod 6, so that the first support plate 5 and the second support plate 7 form an inclined angle, and the inclined angle is also the bending angle of the patient's legs. While being inclined, the inclined angle is adjusted by using the protractor, and the angle is adjusted according to the comfort of the patient and the angle required in the related examination. The threaded column 1002 has a self-holding function, so that after being rotated to the position, no additional positioning and holding are required.
