[0022] Preferably: The mounting seat 1, the bearing 2, the motor 3, the bidirectional lead screw 4 and the sliding tube 5 form a threaded connection structure, and the two sliding tubes 5 are respectively threadedly connected to both sides of the bidirectional lead screw 4.

[0023] During specific use, start the bidirectional lead screw 4 to drive the connected bidirectional lead screw 4 to rotate within the two side bearings 2. While the bidirectional lead screw 4 rotates, the sliding tubes 5 connected on both sides move threadedly on the bidirectional lead screw 4 together.

[0024] Preferably: Two rectangular through grooves are formed on the side wall of the mounting seat 1, and the shape and size thereof are consistent with the limiting rods on one side of the sliding tube 5.

[0025] During specific use, when the sliding tube 5 moves, the limiting rods sliding on the through grooves on the side wall of the mounting seat 1 limit the position of the sliding tube 5.

[0026] Preferably: The sliding tube 5, the telescopic rod 6 and the mounting rod 7 form a telescopic connection structure, and the mounting seat 1, the support plate 8 and the electric telescopic cylinder 9 form a telescopic connection structure.

[0027] During specific use, while the electric telescopic cylinder 9 extends to drive the support plate 8 to move upward, the mounting rod 7 slidably connected to the top of the support plate 8 extends upward on the sliding tube 5 under the action of the telescopic rod 6 at the bottom, facilitating the adjustment of the heights of the limiting plate 10 and the headrest 12.

[0028] Preferably: A chute is formed on the top of the support plate 8, and the shape and size thereof are consistent with the bottom slider on one side of the mounting rod 7. A "T"-shaped chute is formed on the side wall of the mounting rod 7, and the shape and size thereof are consistent with the convex block on one side of the limiting plate 10.

[0029] During specific use, when the mounting rod 7 is driven by the bidirectional lead screw 4 to move, its bottom moves within the chute at the upper end of the support plate 8 to facilitate its support. Meanwhile, the chute formed on one side of the mounting rod 7 facilitates the installation and adjustment of the position of the limiting plate 10 thereon.

[0030] Preferably: The mounting rod 7, the limiting plate 10 and the fixing bolt 11 form a threaded connection structure. A row of threaded grooves are formed at equal intervals on the outer side wall of the limiting plate 10, and the shape and size thereof are consistent with the fixing bolt 11.

After adjustment, the fixing bolt 11 passes through the mounting rod 7 and is fixed in the threaded groove at the corresponding position formed on one side of the limiting plate 10 to fix its position.

[0032] Working principle: When performing ophthalmic surgery on elderly patients, the mounting base 1 is installed on one side of the operating table. Then, the patient's head is placed on the headrest 12. Next, the bidirectional lead screw 4 is started to drive the connected bidirectional lead screw 4 to rotate within the two side bearings 2. While the bidirectional lead screw 4 rotates, the sliding tubes 5 connected on both sides move in a threaded manner on the bidirectional lead screw 4. When the sliding tubes 5 move, the position-limiting rods sliding on the through grooves on the side wall of the mounting base 1 limit the positions of the sliding tubes 5, causing them to move parallel to the mounting base 1, thereby driving the mounting rods 7 and the position-limiting plates 10 connected thereto to move inward together. The position-limiting plate 10 is driven by the mounting rod 7 to move towards the point on the top of the position-limiting plate 10, so that the position-limiting plate 10 abuts against both sides of the elderly patient's head to fix the head. At the same time, when used by people with a larger body size, when the electric telescopic cylinder 9 extends to drive the support plate 8 to move upward, the mounting rod 7 slidably connected to the top of the support plate 8 extends upward on the sliding tube 5 under the action of the bottom telescopic rod 6, facilitating the adjustment of the heights of the position-limiting plate 10 and the headrest 12. It is also possible to adjust the intersection of the position-limiting plate 10 and the mounting rod 7 according to the patient's position on the operating table, thereby extending or shortening the distance between the position-limiting plate 10 and the other side of the operating table, which is convenient for patients with a higher or lower height to use. After adjustment, the fixing bolt 11 is passed through the mounting rod 7 and fixed in the threaded groove opened at the corresponding position on one side of the position-limiting plate 10 to fix its position.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
