[0013] The working principle and beneficial effects of the present invention are: 1. In the present invention, when the patient's eyes are inspected and treated, the adjusting turntable in the lifting assembly is rotated according to the patient's height, the adjusting turntable drives the adjusting worm to rotate, the adjusting worm drives the adjusting worm wheel to rotate, the adjusting worm wheel drives the adjusting ball nut column to rotate, the rotation of the adjusting ball nut group drives the adjusting screw to move, and under the limiting action of the lifting limit rod, the movement of the adjusting screw drives the lifting plate to move, the movement of the lifting plate drives the adjusting tray to move, and the movement of the adjusting tray drives the lower jaw positioning block to move, and after the lower jaw positioning block is moved to a specified height, the patient's lower jaw can be placed on the lower jaw positioning block. Under the self-locking cooperation of the adjusting worm and the adjusting worm wheel, not only the stability of the lower jaw positioning block is greatly improved, but also the position of the lower jaw positioning block can be arbitrarily adjusted according to the patient's height, which is convenient for positioning the patient's head. 2. According to the present invention, after the patient's lower jaw is placed on the lower jaw positioning block, the third positioning bolt on the head positioning assembly can be removed according to the position of the patient's head, and then the head positioning rod can be slid so that the head positioning rod drives the head positioning block to move, and the head positioning block is moved to both sides of the patient's head, and then the positioning bolt three is tightened to fix the position of the head positioning rod, and then the positioning turntable is rotated, and the positioning turntable drives the two-way positioning screw rod to rotate, so that the two head supporting parts on the two-way positioning screw rod move relatively, so that the head positioning block contacts both sides of the patient's head, and the patient's head is fixed. When the head positioning block contacts the patient's head, the extrusion pressure between the head positioning block and the patient's head can be detected by the pressure sensor. When the pressure reaches the preset value, the pressure indicator light will alarm and display, and the medical staff can stop rotating the positioning turntable at this time; 3. In the present invention, after positioning the patient's head, the limiting bolt, the first positioning bolt and the second positioning bolt are loosened, and the position of the protective frame support is moved by sliding the first-level positioning cylinder on the positioning frame, the second-level positioning cylinder in the first-level positioning cylinder, and the third-level positioning cylinder in the second-level positioning cylinder, and the protective frame support is moved to the front of the patient's eyes, and then the manual positioning block is pinched to make the two manual positioning blocks on the eye positioning assembly move relative to each other, and the movement of the manual positioning block drives the eyelid positioning slide plate to move, and the movement of the eyelid positioning slide plate drives the positioning spring to stretch and deform, and the movement of the eyelid positioning slide plate drives the eyelid positioning block to move. Then, the two eyelid positioning blocks on the eye positioning assembly are respectively brought into contact with the upper eyelid and lower eyelid of the patient, and the manual positioning block is loosened. Under the action of the rebound force of the positioning spring, the patient's eyes are supported by the friction between the eyelid positioning block and the patient's eyelid. Finally, the position of the eye positioning assembly can be positioned by tightening the limit bolt, positioning bolt one and positioning bolt two. After the patient's eyes are opened by the eye positioning assembly, under the action of the protective frame support, not only can the patient's eyes be protected to prevent external objects from stimulating the patient's eyes, but also it is convenient for medical staff to detect and treat the patient's eyes through the treatment cavity.
