[0027] A pressing assembly 2 is provided on the top of the mainboard 1, and the pressing assembly 2 includes a structural frame 201 welded to the top of the mainboard 1, an adjusting screw 202 is penetrated by bolts on the top of the structural frame 201, and the bottom end of the adjusting screw 202 is connected to a rubber pressure plate 203 through a bearing.

[0028] When in use, when the device is moved to the outside of the optical lens to be clamped, the cylinder 501 is turned on to push the clamping ring 502 to move, so that the optical lens can be clamped;

[0029] The sliding sleeve 3 is sleeved on the outside of the main board 1, so that the side plate 4 can be moved, which is convenient for adjusting the distance between the clamping rings 502, so that the device can clamp optical lenses of different diameters;

[0030] When the cylinder 501 pushes the clamping ring 502 to clamp the bottom of the stacked optical lenses, the adjusting screw 202 is rotated to push the rubber pressure plate 203 downward, and the rubber pressure plate 203 pressed on the stacked optical lenses can press them tightly, so that the device can clamp the stacked optical lenses.

[0031] In order to fix the moved sliding sleeve 3, for example, Figure 2 As shown, the utility model also includes that two ends of one side of the sliding sleeve 3 are connected with fixing bolts 7 through threaded grooves, and two ends of one side of the main board 1 are equidistantly provided with card slots 6.

[0032] When in use, the moving sliding sleeve 3 can be fixed by tightening the fixing bolt 7 so that one end of the fixing bolt 7 is inserted into the clamping groove 6 .

[0033] For example, Figure 3 As shown, the utility model also includes that two ends of one side of the clamping ring 502 are connected with auxiliary rods 504 through thread grooves, and the auxiliary rods 504 pass through the side plate 4.

[0034] When in use, the provision of the auxiliary rod 504 can improve the structural stability of the clamping ring 502 without affecting the movement thereof.

[0035] For example, Figure 3 As shown, the utility model further includes that a rubber pad 503 is glued to one side of the clamping ring 502 away from the side plate 4 .

[0036] When in use, the rubber pad 503 plays an anti-slip role, so that the clamping ring 502 will not scratch the surface of the optical lens.

[0037] For example, Figure 1 As shown, the utility model also includes that a mounting block 9 is welded to one side of the mainboard 1 between the card slots 6 , and limiting blocks 8 are welded to both ends of the mainboard 1 .

[0042] When the device moves to the outside of the optical lens to be clamped, the adjusting screw 202 can be rotated to push the rubber pressure plate 203 downward so that the rubber pressure plate 203 is pressed on top of the stacked optical lenses. When the cylinder 501 is opened to push the clamping ring 502 to clamp the bottom of the stacked optical lenses, the rubber pressure plate 203 that moves downward and presses on top of the stacked optical lenses can press them tightly, so that the device can clamp the stacked optical lenses.
