[0011] Preferably, the collar is provided with protrusions, and the protrusions are arranged in a ring shape in a plurality of groups.

[0012] The utility model adopts the above structure to achieve the following beneficial effects:

[0013] 1. By setting a fixed column and a movable column, the movable column is driven to move by the rotation of the connecting plate and the damping shaft, and the distance between the movable column and the fixed column is adjusted, so that the loops on both sides of the artificial lens can be fixed, thereby limiting the position of the artificial lens, avoiding collision and damage between the artificial lens and the side wall of the accommodating cavity during packaging and transportation, and ensuring the quality of the artificial lens;

[0014] 2. By providing the screw ring and the spring sheet, and utilizing the engagement of the clamping block with the protrusion, the ring can be limited in position to avoid deflection of the ring during transportation, thereby ensuring the stable fixation of the artificial lens.
