[0002] Orthokeratology lenses are a special type of contact lens that reshapes the cornea when worn overnight, providing clear vision during the day without the need for eyeglasses. They effectively control myopia progression and are suitable for teenagers whose myopia is increasing rapidly.

[0003] When inserting or removing contact lenses, tools or fingers are usually used to pry the lens open, and then a suction cup and airbag are used to complete the operation. However, the suction cup and the suction cup are usually fixedly connected, which makes it impossible to adjust the angle of the suction cup. In actual use, when there are small foreign objects on the edge of the contact lens or when it is necessary to remove or remove it from a certain angle, the fixed-angle suction cup is difficult to fit and operate accurately, which is quite inconvenient.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-3 The device shown includes an orthokeratology contact lens handling device, comprising an airbag 1 and a suction cup 2. A mounting base 3 is fixedly connected to the top of the airbag 1. A groove is formed inside the mounting base 3, and a rotating head 4, connecting the airbag 1 and the suction cup 2, is rotatably mounted inside the groove. The suction cup 2 is fixedly connected to the inner cavity of the rotating head 4. A fixing mechanism 5 is provided on the mounting base 3, comprising a fixing ring 51, a fixing plate 52, and a compression assembly 53. External threads are formed on the outer wall of the mounting base 3, and the fixing ring 51 is threadedly inserted into the mounting base 3. Fixing grooves are formed on both sides of the inner wall of the groove, and the fixing plate 52 is located in the fixing groove. Inside the mounting base 3, the squeezing component 53 is located to drive the displacement of the fixing plate 52. The angle of the suction cup 2 on the mounting base 3 can be adjusted by rotating the head 4. The squeezing component 52 can be squeezed by rotating the fixing ring 51 in the fixing mechanism 5, so that the rotating head 4 can be clamped and fixed by the fixing plate 52 after rotation. With this design, the user can easily adjust the angle of the suction cup according to different picking and putting needs to ensure accurate gripping of contact lenses. The existence of the fixing mechanism ensures that the adjusted angle will not change arbitrarily, providing the user with a stable and reliable operating experience.

[0028] Specifically, the extrusion assembly 53 includes a connecting rod 531, a sliding rod 532, a slider 533, a compression spring 534, a mounting plate 535, and a fixing pin 536. The inner wall of the fixing ring 51 has an extrusion groove. One end of the connecting rod 531 is fitted against the inner wall of the extrusion groove. The cross-section of the extrusion groove is trapezoidal. The end of the connecting rod 531 that is fitted against the extrusion groove also has a bevel at an angle corresponding to the extrusion groove. The other end of the connecting rod 531 passes through the mounting base 3 and is fixedly connected to the fixing plate 52. Mounting slots are provided on both sides of component 3. One end of the sliding rod 532 is fixedly connected to the inner wall of the mounting slot. The slider 533 is slidably inserted into the sliding rod 532. The slider 533 is fixedly connected to the connecting rod 531. A compression spring 534 is sleeved on the outside of the sliding rod 532. One end of the compression spring 534 is in contact with the slider 533, and the other end of the compression spring 534 is in contact with the inner wall of the mounting slot. The compression spring 534 is always in a compressed state, so the connecting rod 531 can be controlled by the slider 533. A stable elastic force is provided, allowing one end of the connecting rod 531 to fit tightly against the inner wall of the extrusion groove. When the fixing ring 51 rotates, it undergoes corresponding displacement, thereby driving the fixing plate 52 to move and completing the clamping and releasing operation of the rotating head 4. This ensures that the angle of the rotating head 4 does not change arbitrarily after adjustment, making the angle adjustment of the suction cup 2 more stable and reliable. The mounting plate 535 is slidably inserted into the inner cavity of the mounting groove. The cross-section of the mounting groove is L-shaped. The outer wall of the mounting plate 535 has a countersunk hole, and the inner wall of the mounting groove has a fixing hole. The fixing pin 536 passes through the countersunk hole and is threaded into the inner cavity of the fixing hole. The mounting plate 535 can be installed inside the mounting groove through the fixing pin 536. When the internal compression spring 534 reaches the end of its service life, the mounting plate 535 can be removed by disassembling the fixing pin 536, and the slider 533 can be slid out from the slider 532. This allows the compression spring 534 to be removed from the inside and replaced for easy use.

[0029] Furthermore, rubber pads 6 are fixedly connected to opposite sides of the fixing plate 52. The outer wall of the rubber pads 6 has anti-slip texture. The rubber pads 6 increase the friction between the fixing plate 52 and the rotating head 4. After adjusting and fixing the angle of the rotating head 4, it can effectively prevent the rotating head 4 from rotating accidentally, ensuring the stability and reliability when taking out and putting in contact lenses. Even if a certain external force is applied during operation, the rubber pads 6 can firmly fix the rotating head 4, allowing users to take out and put in contact lenses with more confidence.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
