[0037] By providing the spring 10 , the slider 11 can be driven to slide and reset.

[0038] As a preferred implementation in this embodiment, refer to the attached Figure 2 The inner wall of the connecting plate 2 is fixedly connected with an L-shaped rod 9, and the L-shaped rod 9 has a certain toughness.

[0039] By providing the L-shaped rod 9, the L-shaped rod 9 has a certain toughness, and after the L-shaped rod 9 is subjected to force, the L-shaped rod 9 itself can be driven to undergo a certain bending deformation.

[0045] By setting the second suction cup 7 and the first suction cup 3 to be made of nitrile rubber, the surfaces of the second suction cup 7 and the first suction cup 3 are in contact and pressed with the surface of the lens, so that the lens can be better adsorbed.

[0046] The working principle of the utility model is as follows: a special clamp for ultra-thin lenses. When in use, the user aligns the multiple second suction cups 7 with the first suction cup 3 to be clamped and adsorbed ultra-wave lenses, and after lightly contacting and pressing, pulls the pull rod 8 upwards. The pull rod 8 moves and drives the piston 13 to rise in height through the motion rod 12. At this time, air is pumped into the air cylinder 1 through the first air supply pipe 14, the bellows 15, the second air supply pipe 28, and the first movable cylinder 17. During the movement of the motion rod 12, the slider 11 is pushed to move. At this time, the L-shaped rod 9 is guided along the guide groove 25, and the L-shaped rod 9 is bent and deformed by force until one end of the L-shaped rod 9 is located in the guide groove 25 and is clamped in the limit clamping groove 26 to prevent the slider 11 from moving as a whole. At this time, the piston 13 stops moving, and the connecting plate 2 is held as a whole to drive the adsorbed multiple optical lenses to be clamped and transported. When it is necessary to adjust the position of the slide cylinder 6 on the positioning cylinder 5, the screw 16 can be turned to release the contact between the surface of the convex plate 20 and the positioning groove 27, and the slide After adjusting the slide 6 to the appropriate position, the reverse screw 16 clamps the convex plate 20 in the corresponding positioning groove 27 for fixing. When it is necessary to adjust the angular orientation of the second suction cup 7, the screw 23 is rotated to drive the U-shaped plate 24 to slide on the surface of the mounting plate 18, so that one side of the mounting plate 18 is rotated as a whole under the force, driving the second movable cylinder 29 and the arc plate 21 to rotate as a whole, thereby adjusting the angle of the second suction cup 7. At this time, the direction of the air exchange hole 22 is always located in the first movable cylinder 17. When it is necessary to release the adsorption state of the second suction cup 7 and the first suction cup 3 on the lens, the operator slightly pushes the pull rod 8 upwards, drives the slider 11 to slide, and then releases the pull rod 8. The slider 11 is pushed to reset under the action of the spring 10, and the piston 13 is driven down by the moving rod 12 to push the air in the air cylinder 1 into the second suction cup 7 and the first suction cup 3 to release the adsorption state. With the above structure, multiple thinner optical lenses can be clamped and transported at the same time to avoid damage to the thinner optical lenses.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
