[0043] The U-shaped slide 31 is provided with a side groove that matches the square bar 32, and the cross-section of the side groove is rectangular. The two guide plates 35 are symmetrically arranged about the pull rod 26. Each guide plate 35 is provided with a guide groove 351 that matches the transmission slider 321.

[0044] When limiting the patient's eyelids, the two auxiliary device bodies 11 can be rotated separately so that the right-angled rotating rod fixed on the auxiliary device body 11 rotates around the contact position with the support rod, and the bottom of the right-angled rotating rod contacts the side wall of the support rod. The first expansion clamp 12 and the second expansion clamp 121 can be pulled, and the inner parts of the first expansion clamp 12 and the second expansion clamp 121 can be respectively contacted with the patient's eyelid part. At this time, the second expansion clamp 121 and the first expansion clamp 12 both rotate around the connection position with the auxiliary device body 11, and at the same time drive the two groups of inner push plates 21 respectively rotating on the second expansion clamp 121 and the first expansion clamp 12 to rotate around the connection position with the connecting piece 221 at the same time, thereby driving the inner sliding plate fixed at the bottom end of the connecting piece 221 The seat 22 slides inside the auxiliary device body 11. The sliding of the inner sliding seat 22 can drive the pushing rotating plate 23 connected to it to rotate around the connection position with the main rotating rod 24, and then drive the main rotating rod 24 to rotate around the connection position with the auxiliary device body 11. At the same time, the rotation of the main rotating rod 24 can drive the tear collecting seat 25 rotating at the bottom end of the main rotating rod 24 to make a circular motion. At the same time, the top end of the pull rod 26 can rotate around the inner wall of the protective seat 13, and the two side sliders 261 fixed at the other end of the pull rod 26 can slide inside the movable slide groove, so that the soft silicone material at the bottom end of the tear collecting seat 25 can fit the position of the patient's eye corner, and the cooperation of the tear collecting seat 25 and the magnetic tear bag 36 can collect the tears produced by the patient during the operation.

[0045] In the process of limiting the patient's eyelids, Figure 8 , the two side sliders 261 can slide toward the left, and at the same time drive the U-shaped slide 31 fixed on the two side sliders 261 to slide. At this time, the square bar 32 slidably connected to the inside of the U-shaped slide 31 can move simultaneously with the sliding of the U-shaped slide 31, and the transmission sliders 321 fixed on both sides of the square bar 32 can slide inside the guide groove 351 opened on the guide plate 35. As the U-shaped slide 31 continues to slide, the transmission slider 321 can slide from the smooth groove to the inside of the inclined groove. At the same time, under the connection of the connecting rod 33, the transmission sliders 321 fixed on the two transmission sliders 321 can slide. The bottom end of the scraper body 34 can be separated from the bottom end of the inner wall of the tear collection seat 25 to facilitate the entry of the patient's tears. During the disassembly of the auxiliary device body 11, the side slider 261 can slide to the right, and the two transmission sliders 321 can enter the smooth groove from the inside of the inclined groove, so that the bottom end of the scraper body 34 contacts the bottom end of the inner wall of the tear collection seat 25. As the U-shaped slide 31 continues to move, the transmission slider 321 can be driven to continue to slide inside the smooth groove. At this time, the scraper body 34 can scrape and collect the tears remaining at the bottom end of the inner wall of the tear collection seat 25.

[0046] The limiting assembly 4 includes a telescopic fixing seat 41 fixed on the auxiliary device body 11, a telescopic rod 42 is inserted into the telescopic fixing seat 41, an arc-shaped limiting rod 44 is fixedly provided on the telescopic rod 42, two groups of limiting teeth 45 are fixedly provided on the arc-shaped limiting rod 44, and the top of the first expansion clamp 12 and the second expansion clamp 121 are respectively fixedly provided with limiting protrusions 46 that contact the two groups of limiting teeth 45.

[0047] A return spring 43 is sleeved on the arc-shaped outer wall of the telescopic rod 42 . One end of the return spring 43 is fixedly connected to the end of the telescopic rod 42 , and the other end of the return spring 43 is fixedly connected to the telescopic fixing seat 41 .

[0048] During the process of limiting the patient's eyelids, the telescopic rod 42 can be pushed to separate the multiple limiting teeth 45 fixed on the arc-shaped limiting rod 44 from the two limiting protrusions 46. During this process, the return spring 43 sleeved on the telescopic rod 42 can be compressed, and the first expansion clamp 12 and the second expansion clamp 121 can be pulled respectively, and the first expansion clamp 12 and the second expansion clamp 121 can be rotated around the connection position with the auxiliary device body 11 respectively, and the torsion spring fixed between the first expansion clamp 12 and the second expansion clamp 121 can be compressed at the same time. When the positions of the first expansion clamp 12 and the second expansion clamp 121 are adjusted to the desired positions, the telescopic rod 42 can be loosened. At this time, under the action of the elastic force of the return spring 43, the limiting teeth 45 on the arc-shaped limiting rod 44 contact with the limiting protrusions 46 on the first expansion clamp 12 and the second expansion clamp 121, which can achieve the purpose of limiting.

[0049] The working principle and usage process of the present invention are as follows: when limiting the eyelids of the patient, the two auxiliary device bodies 11 can be rotated separately, so that the right-angle rotating rod fixed on the auxiliary device body 11 rotates around the contact position with the support rod, and the bottom of the right-angle rotating rod contacts the side wall of the support rod, and the telescopic rod 42 can be pushed to separate the multiple limiting teeth 45 fixed on the arc-shaped limiting rod 44 from the two limiting protrusions 46. In this process, the return spring 43 sleeved on the telescopic rod 42 can be compressed, and the first expansion clip 12 and the second expansion clip 121 can be pulled separately, and the first expansion clip 12 and the second expansion clip 121 can be rotated around the connection position with the auxiliary device body 11 respectively, and the first expansion clip 12 and the second expansion clip 121 can be compressed and fixed at the same time. The torsion spring between the tension clamps 121 makes the inner parts of the first expansion clamp 12 and the second expansion clamp 121 contact the patient's eyelid part respectively, and at the same time drives the two groups of inner push plates 21 rotating on the second expansion clamp 121 and the first expansion clamp 12 to rotate around the connection position with the connecting piece 221 at the same time, thereby driving the inner sliding seat 22 fixed at the bottom end of the connecting piece 221 to slide inside the auxiliary device body 11. The sliding of the inner sliding seat 22 can drive the pushing rotating plate 23 connected to it to rotate around the connection position with the main rotating rod 24, and then drive the main rotating rod 24 to rotate around the connection position with the auxiliary device body 11. At the same time, the rotation of the main rotating rod 24 can drive the tear collecting seat 25 rotating at the bottom end of the main rotating rod 24 to make a circular motion, and at the same time pull The top end of the rod 26 can rotate around the inner wall of the protective seat 13, and the two side sliders 261 fixed at the other end of the pull rod 26 can slide inside the movable slide groove, so that the soft silicone material at the bottom end of the tear collection seat 25 can fit the position of the patient's eye corner, and the tear collection seat 25 cooperates with the magnetic tear bag 36 to collect the tears produced during the patient's operation. At the same time, the two side sliders 261 can slide to the left, and then drive the U-shaped slide 31 fixed on the two side sliders 261 to slide. At this time, the square bar 32 slidably connected to the inside of the U-shaped slide 31 can move simultaneously with the sliding of the U-shaped slide 31, and the transmission sliders 321 fixed on both sides of the square bar 32 can slide inside the guide groove 351 opened on the guide plate 35. The continuous sliding of the U-shaped slide 31 can make the transmission slide 321 slide from the smooth groove to the inside of the inclined groove. At the same time, under the connection of the connecting rod 33, the bottom end of the scraper body 34 fixed on the two transmission slides 321 can be separated from the bottom end of the inner wall of the tear collection seat 25, which is convenient for the patient's tears to enter. In the process of disassembling the auxiliary device body 11, the side slide 261 can slide to the right, and the two transmission slides 321 can enter the smooth groove from the inside of the inclined groove, so that the bottom end of the scraper body 34 contacts the bottom end of the inner wall of the tear collection seat 25. As the U-shaped slide 31 continues to move, the transmission slide 321 can be driven to slide continuously inside the smooth groove. At this time, the scraper body 34 can scrape and collect the tears remaining at the bottom end of the inner wall of the tear collection seat 25.When the positions of the first expansion clamp 12 and the second expansion clamp 121 are adjusted to the desired positions, the telescopic rod 42 can be loosened. At this time, under the elastic force of the return spring 43, the limiting teeth 45 on the arc-shaped limiting rod 44 contact the limiting protrusions 46 on the first expansion clamp 12 and the second expansion clamp 121, which can achieve the purpose of limiting.
