[0029] In the embodiment provided in the present application, the height adjustment unit includes a telescopic rod 8 and a driving member 7, one end of the telescopic rod 8 is arranged on the base 1, the driving member 7 is symmetrically arranged on the outside of the chin support 6, and the other end of the telescopic rod 8 is connected to the driving member 7.

[0030] The telescopic rod 8 can be hydraulic or electric, as long as the height of the driving member 7 can be adjusted. The driving member 7 can adopt a dual-motor structure to drive two concentric rods or tubes to achieve different rotation directions or speeds. The above are all existing technical means, which can be known to technicians in this field, so they will not be elaborated.

[0031] In the embodiment provided in the present application, the distance adjustment unit includes a screw 12 and a threaded sleeve 11. The screw 12 is arranged on the top of the driving member 7, and the threaded sleeve 11 is symmetrically arranged on the outside of the sliding sleeve 9. The screw 12 at least partially penetrates the threaded sleeve 11, and one end of the screw 12 is connected to the driving member 7.

[0032] When the screw 12 rotates, under the action of the support rod 5 and the sliding sleeve 9, the threaded sleeve 11 can move up and down along the outer side of the screw 12, thereby driving the forehead support 10 to move synchronously, and then adjusting the distance between the forehead support 10 and the chin support 6.

[0033] In the embodiment provided in the present application, the positioning unit includes a sleeve 13, a bracket 14 and a face support 15. The sleeve 13 is arranged on the driving member 7, the bracket 14 is arranged on the sleeve 13, the face support 15 is arranged on the sleeve 13, and the screw 12 passes through the interior of the sleeve 13.

[0034] The sleeve 13 and the screw 12 can rotate independently. In addition, the sleeve 13 and the driving member 7 move upward or downward synchronously, and different sleeves 13 can also rotate independently, which is convenient for adjusting the patient's eyes in the horizontal direction.

[0035] In the embodiment provided in the present application, the top of the chin support 6 is concave, the outer side of the forehead support 10 is arc-shaped, and the two facial supports 15 are symmetrical arc-shaped, so as to facilitate the fixation of the eye position.
