The outside of the limiting damping unit is fixedly connected to the inner wall of the operating table through a mounting bracket.

[0009] Furthermore, the closing component includes a rotating shaft. The rotating shaft is rotatably connected inside the mounting frame. One end of the rotating shaft extends to the outside of the mounting frame and is fixedly connected with a hand crank. A cavity is formed inside the mounting frame.

[0010] Furthermore, the end of the rotating shaft away from the hand crank extends into the cavity and is fixedly connected with a disc. The disc is rotatably connected inside the mounting frame.

[0015] Compared with the prior art, the beneficial effects of this solution are as follows: 1. Through the arranged heat dissipation and cleaning assembly in this solution, the driving motor drives the hollow shaft and the fan blade to rotate clockwise. During the clockwise rotation of the fan blade, external air is extracted through the heat dissipation through holes, and the filter screen filters the dust in the external air, reducing the adverse effects of dust in the air on the internal components of the operating table. When the filter screen becomes blocked during long-term use of the device, the driving motor drives the hollow shaft, the fan blade and the inner ratchet groove to rotate counterclockwise. The inner ratchet groove drives the round wheel, the connecting shaft, the mounting frame and the cleaning block to rotate through the ratchet pawl and the fixed shaft. The surface of the filter screen is automatically cleaned by the mounting frame and the cleaning block. During the counterclockwise rotation of the fan blade, the gas inside the device is extracted. While ensuring heat dissipation, the extracted gas discharges the impurities cleaned by the cleaning block outside the operating table, preventing the dust raised during the cleaning process from entering the operating table, and further improving the overall performance of the device.

[0016] 2. Through the arranged sealing assembly in this solution, the teacher manually operates the hand crank to drive the rotating shaft, the disc and the connecting block to rotate, and the connecting block drives the second protective layer to rotate around the rotating shaft. During the non-use process of the device, the second protective layer seals and protects the filter screen, reducing the influence of external air dust and moisture on the internal components of the operating table, and thus preventing the operation accuracy and performance of the device from being affected.

[0017] 3. Through the arranged protection and cleaning assembly in this solution, during the non-use process of the device, the teacher manually operates the dial block to drive the vertical plate to squeeze the first spring. When the dial block contacts the surface of the fixed block, the fixed block and the dial block can be limited and fixed through the adjusting bolt. During the movement of the vertical plate, the surface of the display screen is assisted in cleaning through the sponge block, reducing the dust adhered to the surface of the display screen, and thus preventing the clarity of the operation display screen of the display screen from being affected. At this time, the first protective layer protects the display screen, reducing the damage to the display screen caused by external factors during the non-use process of the device, and thus effectively improving the protection performance of the device during use.
