During the lifting process, the lifting plate 18 drives the arc plate 1 to lift through the second mounting plate 19. When the arc plate 1 is adjusted to the appropriate After reaching the height, stop the electric push rod 28, thereby completing the adjustment of the height of the arc plate 1;

Embodiment 2, as shown in Figures 1 to 6, after the height adjustment of the arc-shaped plate 1 is completed, the position where the patient needs surgery is placed inside the arc-shaped plate 1, and then the part where the patient needs surgery is adjusted. , and then rotate the two-way threaded rod 10. The two-way threaded rod 10 drives the two sets of first mounting plates 4 to approach each other during the rotation. When the two sets of first mounting plates 4 approach each other, the moving rod 2 is driven through the connecting ring 3. Move so that the two sets of second pressure plates 14 are close to each other, so that the two sets of second pressure plates 14 components clamp the sides of the patient, thereby ensuring a certain positioning effect on the patient's surgical site, and then pull the first insertion rod 21, When the first insertion rod 21 is pulled again, the first spring 20 is stretched, so that the first insertion rod 21 is separated from the inside of the first socket 13, and the lifting rod 11 is no longer restricted, and then the lifting rod 11 is pulled, so that The lifting rod 11 moves, and the lifting rod 11 drives the first pressure plate 12 to move during the movement, so that the first pressure plate 12 is close to the patient, thereby completing the adjustment of the first pressure plate 12. If the first pressure plate 12 is positioned When the patient's surgical site cannot be well positioned during the process, the rotating plate 25 is first pulled. The rotating plate 25 drives the second spring 24 to compress during the pulling process, and at the same time, the second insertion rod 22 is moved from the second jack 26 The inside of the rotating rod 23 is detached, so that the rotation rod 23 is no longer limited, and then the rotating rod 23 is rotated.
