Among them, a card slot 3 for the seat back to move into is opened on the support seat 2. The positioning device includes a fixed frame 5, a guide block 6 and a pressing plate 7. The bottom of the fixed frame 5 is fixedly connected to the top of the operating table 1. The guide block 6 is movably arranged inside the fixed frame 5. Connecting blocks 12 are fixedly connected to both sides of the guide block 6. The two connecting blocks 12 are respectively movably arranged in through holes opened on the opposite inner walls of the fixed frame 5. And an elastic telescopic member is connected between the bottom of the guide block 6 and the inner wall of the fixed frame 5. The top of the guide block 6 is an inclined surface facing the center of the operating table 1. When the seat back touches the inclined block of the guide block 6, it can move along the inclined surface of the guide block 6, which plays a certain guiding role in the horizontal movement of the seat back. An elastic positioning member is movably arranged in a groove opened on the side wall of the guide block 6. A positioning groove 9 for cooperating with the elastic positioning member is opened on the inner wall of the fixed frame 5. One end of the pressing plate 7 is fixedly connected to the side wall of the guide block 6. As the seat back moves down, the bottom of the seat back touches a plurality of pressing plates 7. Since multiple points at the bottom of the seat back are in contact with the pressing plates 7, the seat back is in a horizontal state at this time, making it not easy for the seat back to tilt at one end;

[0025] The elastic positioning member includes a second spring 10 and a positioning block 11. The positioning block 11 is movably arranged in the groove on the side wall of the guide block 6. One end of the positioning block 11 away from the guide block 6 is an upward inclined surface. The size of the positioning groove 9 is adapted to the size of the positioning block 11. The two ends of the second spring 10 are respectively fixedly connected to the end of the positioning block 11 and the bottom wall of the groove of the guide block 6. The elastic telescopic member is a first spring 8. The two ends of the first spring 8 are respectively fixedly connected to the bottom of the guide block 6 and the inner wall of the fixed frame 5. The pressing plate 7 drives the guide block 6 to move down in the fixed frame 5. When the positioning block 11 is facing the positioning groove 9, under the action of the compressed second spring 10, the positioning block 11 enters the positioning groove 9. At this time, the bottom edge of the seat back enters the card slot 3, which is convenient for positioning the downward movement position of the seat back;

[0026] The clamping device includes a mounting seat 13, an electric cylinder 14 and a clamping plate 15. The bottom of the mounting seat 13 is fixedly connected to the top of the operating table 1.

[0027] The working principle provided by the present utility model is as follows: When using the device, the seat back is gradually lowered. When the seat back contacts the inclined block of the guide block 6, it can move along the inclined surface of the guide block 6, which plays a certain guiding role in the horizontal movement of the seat back. As the seat back is lowered, the bottom of the seat back contacts multiple pressing plates 7. Since multiple points at the bottom of the seat back are in contact with the pressing plates 7, the seat back is prone to being in a horizontal state at this time. Then, press the seat back. The seat back presses the pressing plates 7, and the pressing plates 7 drive the guide block 6 to move downward in the fixed frame 5. When the positioning block 11 is aligned with the positioning groove 9, under the action of the compressed second spring 10, the positioning block 11 enters the positioning groove 9. At this time, the bottom edge of the seat back enters the clamping groove 3, thus completing the placement work of the seat back. The clamping plate 15 is driven by the electric cylinder 14 to move, thereby completing the clamping work of the seat back. After the processing is completed, under the action of the first spring 8, the inclined surface of the positioning block 11 moves into the groove of the guide block 6 under extrusion, the second spring 10 is compressed, and the guide block 6 moves upward.
