DETAILED DESCRIPTION
[0019] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.
[0021] like Figure 1-3 As shown, the utility model proposes an ophthalmic eyelid retractor, comprising a fixed shell 1, and also comprising a pushing and squeezing mechanism 2 and a supporting and connecting mechanism 3 on the fixed shell 1; the pushing and squeezing mechanism 2 comprises an adjusting groove 4 and a screw rod 5, the adjusting groove 4 is arranged in the fixed shell 1, a slide groove 6 and a movable groove 7 are arranged in the adjusting groove 4, a moving component 8 is arranged on the slide groove 6, the screw rod 5 is rotatably arranged on the side wall of the adjusting groove 4, an squeezing block 9 is threadedly connected to the screw rod 5, one end of the screw rod 5 passes through the side wall of the adjusting groove 4 and extends out, a knob 19 is arranged on the protruding end of the screw rod 5, the knob 19 is turned to drive the screw rod 5 to rotate, the screw rod 5 drives the squeezing block 9 to move, and cooperates with the moving component 8 to open the patient's eyes.
[0022] The moving assembly 8 includes a push block 10 and a sleeve rod 11. The push block 10 is slidably arranged in the slide groove 6. The push block 10 and the extrusion block 9 are staggered and slidably arranged. A spring 12 is arranged between the push block 10 and the side wall of the adjustment groove 4. The sleeve rod 11 is arranged on the push block 10. The sleeve rod 11 is movably inserted into the movable groove 7. A connecting rod 13 is movably inserted in the sleeve rod 11. The connecting rod 13 is provided with a support ring 14. The extrusion block 9 moves under the drive of the screw rod 5 and starts to squeeze the push block 10. The push block 10 is pushed along the slide groove 6 to both sides. The spring 12 is moved and compressed, thereby driving the sleeve rod 11 and the connecting rod 13 to move, so that the expansion ring 14 moves with it. When the screw rod 5 rotates in the opposite direction, the extrusion block 9 is driven to retreat, so that the extrusion block 9 no longer squeezes the push block 10.
