[0034] A vertically downward groove 13 is formed on the top of the fixing seat 15 . The number of the grooves 13 matches that of the clamps 3 . The clamps 3 are slidably disposed in the corresponding grooves 13 .

[0035] The transmission assembly includes a latching tooth 16 and a latching groove 17, and the latching tooth 16 is meshed with the latching groove 17. The latching tooth 16 is fixedly connected to the upper surface of the rotating plate 2, and the latching tooth 16 is arranged in a spiral shape.

[0036] The bottom of the clamp 3 is provided with a clamping groove 17 adapted to the clamping teeth 16. The upper surface of the disc 4 is provided with a slide groove 11, the number of which is adapted to the clamp 3, and the slide groove 11 corresponds to the groove 13 one by one.

[0037] The latch teeth 16 extend into the slide slot 11 , and the bottom end of the clamp 3 is slidably disposed in the corresponding slide slot 11 .

[0038] The end of the clamp 3 extending into the interior of the fixing seat 15 is fixedly connected with an arc plate, and the arc surface of the arc plate is provided with a rubber pad. When the clamp 3 clamps the eyeglass lens, the rubber pad has a protective effect on the eyeglass lens.

[0039] A supporting assembly for placing the eyeglass lens is arranged in the middle of the disk 4 , and the supporting assembly is located between a plurality of clamps 3 .

[0040] The support assembly includes a top plate 5. A support plate 12 is fixedly connected to the interior of the fixing seat 15. A through hole is provided in the middle of the disc 4. A fixing plate 14 is fixedly connected to the bottom surface of the middle of the disc 4. The diameter of the fixing plate 14 is larger than the diameter of the through hole.

[0045] The support plate 12 and the fixing plate 14 are provided with a plurality of water outlet holes, which are arranged in a circular array. When cutting the eyeglass lens, it is necessary to add a coolant to cool the eyeglass lens and the cutting head. The cooled coolant is discharged through the water outlet holes, and the discharged water falls into the water collecting tank 8.

[0046] Working principle:

[0047] When in use, the eyeglass lens to be cut is placed on the top of the top plate 5 and between the multiple clamps 3 .

[0048] The rotating plate 2 is rotated to move upward outside the fixing seat 15. At the same time, the top of the rotating plate 2 rotates on the disc 4, thereby pushing the disc 4 to move upward together, driving the plurality of fixtures 3 to move upward together.

[0049] The rotating plate 2 drives the latching teeth 16 to rotate together, so that the latching teeth 16 push the clamp 3 through the clamping groove 17. The bottom end of the clamp 3 is located in the slide groove 11, so that the clamp 3 slides along the corresponding slide groove 11 toward the top plate 5.

[0050] At the same time, the disc 4 drives the fixing plate 14 to move upward, so that the fixing plate 14 moves upward along the fixing column 7. The fixing plate 14 pushes the spring 6 upward, so that the spring 6 pushes the top plate 5 upward, and the limiting block 10 slides upward in the limiting groove.

[0051] The top plate 5 is moved upward together with the clamp 3 , so that the top plate 5 is always within the clamping range of the clamp 3 .

[0052] As the clamp 3 slides, the clamp 3 clamps the eyeglass lens on the top plate 5. Afterwards, the eyeglass lens is cut into pieces by the cutting head. During the cutting process, the coolant cools the eyeglass lens and the cutting head. The cooled coolant is discharged through the water outlet holes on the fixing plate 14 and the supporting plate 12 in turn, and the discharged water falls into the water collecting tank 8.

[0053] When used for a long time, the water collecting box 8 is pulled by the handle 9 to be removed from the base 1, and the water collecting box 8 is cleaned for reuse.

[0054] After the eyeglass lens is cut, the rotating plate 2 is rotated to move downward, driving the disc 4 to move downward. The clamp 3 moves downward and slides to the side away from the top plate 5, while the fixing plate 14 moves downward and pulls the top plate 5 downward through the spring 6. The eyeglass lens can be removed.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
