DETAILED DESCRIPTION

[0017] 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.

[0018] 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.

[0019] like Figure 1-3 As shown, the utility model proposes an artificial lens durability testing device, including a table 1, and also includes a pushing and squeezing mechanism 2 and a pressing and limiting mechanism 3 arranged on the table 1; the pressing and limiting mechanism 3 includes a push plate 4 and a movable plate 5, the push plate 4 is movably arranged on the table 1, and a slide groove 6 and a bottom plate 7 are arranged on the push plate 4, and a placement plate 8 is arranged on the bottom plate 7, and a placement groove 9 is arranged on the placement plate 8, the movable plate 5 is slidably arranged on the slide groove 6, and a screw rod 10 is rotatably arranged on the movable plate 5, and the screw rod 10 is threadedly connected to the bottom plate 7. A connecting rod 11 is provided on the movable plate 5, and a pressure block 12 is provided at the end of the connecting rod 11. The pressure block 12 is arranged above the placement groove 9. The material of the pressure block 12 and the placement plate 8 are both rubber. The artificial lens is placed in the placement groove 9, and the screw 10 is rotated to drive the movable plate 5 to move along the slide groove 6. The movable plate 5 drives the connecting rod 11 and the pressure block 12 to move, and cooperates with the placement groove 9 to fix the artificial lens. At the same time, the rubber material of the pressure block 12 and the placement groove 9 has good elasticity and will not cause damage to the artificial lens.

[0020] like Figure 1 As shown, the pushing and squeezing mechanism 2 includes a cylinder 13 and a fixed plate 14, both of which are arranged on the table 1, and the output end of the cylinder 13 is connected to the push plate 4, and an extrusion groove 15 is provided on the fixed plate 14. The cross-sectional shape of the extrusion groove 15 is a trapezoidal setting that is wide outside and narrow inside, and the extrusion groove 15 is arranged close to the placement plate 8. The cylinder 13 is started to push the push plate 4 to move, and the push plate 4 drives the bottom plate 7 and the movable plate 5 to move, thereby driving the artificial lens to approach the extrusion groove 15. By adjusting the moving distance of the push plate 4, the side wall of the extrusion groove 15 is used to squeeze the haptics of the artificial lens to different degrees.
