[0032] Specifically, both the first power mechanism and the second power mechanism include a geared motor. The output shaft of the geared motor is connected to a screw 12. The screw 12 is connected to the operating table 1 in a rotating manner. The screw 12 is provided with a connecting seat 13 through threaded engagement. The connecting seat 13 is fixedly connected to the mounting frame 3 or the end limiting mechanism 8.

[0033] It should be noted that the end limiting mechanism 8 includes a base 14 connected to the operating table 1 via a linear guide rail. The upper surface of the base 14 is provided with an inclined column 15 and a column in a fixed structure. The column includes an X-direction vertical plate 16 and a Y-direction vertical plate 17 arranged in a T-shape. An electromagnet is provided in a fixed structure on the X-direction vertical plate 16 inside the Y-direction vertical plate 17.
