The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5, including left right direction and main part 1 that the arc mouth is down, left right direction and rectangular channel 2 that link up from top to bottom have been seted up on the main part 1, the auxiliary groove 3 of fore-and-aft direction has been seted up respectively to the main part 1 left and right sides, sliding connection has the connecting block 4 of left right direction in the auxiliary groove 3, both sides articulate respectively has connecting rod 5 around the connecting

block

4, 5 free ends of connecting rod articulate has pendulum rod 6, the lateral wall articulates on 6 upper ends of pendulum rod and the auxiliary groove 3 is connected, the back of the body side of two pendulum rods 6 in same auxiliary groove 3 articulates respectively has push rod 7, the free end of push rod 7 articulates has the bracing piece 8 of left right direction, the inner of bracing piece 8 stretches into in rectangular channel 2 and is equipped with the eyelid clamp 9 of V.

In order to facilitate the connection block 4 to slide up and down and position the connection block, the auxiliary groove 3 is rotatably connected with an upper axial lead screw 10 and a lower axial lead screw 10, the lead screw 10 penetrates through the connection block 4 on the corresponding side and is in threaded connection with the connection block 4, and the upper end of the lead screw 10 penetrates through the main body 1 and is coaxially provided with a knob 11.

In order to facilitate the sliding of the support rod 8, the main body 1 is provided with two sliding grooves 12 corresponding to the support rods 8 one by one, and the support rods 8 are located in the sliding grooves 12 on the corresponding sides and are connected with the sliding grooves 12 in a sliding manner.

In order to facilitate fixing the main body 1 on the eyes of a patient, the left side and the right side of the main body 1 are respectively provided with a fixing band 13, the free ends of the two fixing bands 13 are respectively provided with a magic tape 14, and the two magic tapes 14 can be mutually bonded.

In order to avoid crushing the nose of the patient, the front side and the rear side of the main body 1 are respectively provided with arc-shaped grooves 15 which are communicated from front to back and have downward openings.

In order to improve the comfort of the patient, the lower side of the main body 1 is provided with a latex pad 16 which is consistent with the shape of the main body.

When the utility model is used, the main body 1 is firstly placed on the eyes of a patient, the fixing band 13 is wound on the head of the patient, after the degree of tightness is adjusted, the two magic tapes 14 are adhered together to stably fix the main body 1 on the head of the patient, and the latex pad 16 and the arc-shaped groove 15 are arranged, so that the nose of the patient is prevented from being pressed, the comfort of the patient can be improved, and the medical staff can conveniently perform eye surgery on the patient;
