The operating table overturning device according to claim 7, wherein a guide block (1-1-3) is arranged on the front lifting column sliding seat (1-1) corresponding to the sliding sleeve (1-6), a boss guide groove is arranged on the guide block (1-1-3) corresponding to the sliding sleeve butt joint boss (1-6-3), and a smooth arc-shaped structure is arranged on the upper portion of the boss guide groove corresponding to the sliding sleeve (1-6);

When the functional bed (4) is in a horizontal state, the boss guide groove is opposite to the deflector rod butt joint groove (1-4-1) and is used for guiding the sliding sleeve butt joint boss (1-6-3) to be inserted into the deflector rod butt joint groove (1-4-1);

When the switching component is switched from the closed state to the open state, one sliding sleeve butt joint boss (1-6-3) slides to one side far away from the guide block (1-1-3) along the boss guide groove, then the functional bed (4) is manually rotated to turn over 180 degrees, then the switching component is switched from the open state back to the closed state, and the other sliding sleeve butt joint boss (1-6-3) slides to be inserted into the deflector rod butt joint groove (1-4-1) along the boss guide groove.

9. The operating table overturning device according to claim 6, wherein an in-place indication plate (1-7-1) is connected to the lower portion of the adapter ring (1-7), an indication vertical plate is arranged at the free end of the in-place indication plate (1-7-1), an in-place sensor (1-1-4) is arranged on the front-end lifting column sliding seat (1-1) corresponding to the indication vertical plate, and the indication vertical plate abuts against the in-place sensor (1-1-4) to indicate that the switching assembly is closed.

10. The operating table overturning device according to claim 1, wherein a slide rail guide block (1-2-2) is arranged on the upper end face of the front end lifting column body (1-2), a slide rail guide groove is formed in the slide rail guide block (1-2-2), a slide rail avoiding groove (1-2-1) is formed in the front end lifting column body (1-2) corresponding to the slide rail guide groove, a slide rail (1-1-2) is arranged on the lower end face of the front end lifting column sliding seat (1-1) corresponding to the slide rail guide groove, and the front end lifting column sliding seat (1-1) is arranged in the slide rail guide groove in a sliding manner through the slide rail (1-1-2);

when the inclination angle of the functional bed (4) relative to the horizontal plane changes, the front lifting column sliding seat (1-1) slides to compensate the displacement of the functional bed (4) in the horizontal direction.
