[0027] And the upper side of the cutting gap 6 is also correspondingly provided with a lifting mechanism 7, the lifting plate 8 is correspondingly arranged on the lifting mechanism 7, and the electric clamping jaws 9 are correspondingly arranged on both sides of the lifting plate 8. The rod-shaped blank 10 of the optical lens is clamped by the electric clamping jaws 9 on both sides, and the rod-shaped blank 10 is moved downward under the driving of the lifting mechanism 7. First, the two side parts of the rod-shaped blank 10 are cut by the cutting blades 4 of the first cutting mechanism 1 and the second cutting mechanism 2. After the rod-shaped blank 10 continues to descend, the middle part of the rod-shaped blank 10 is cut by the third cutting mechanism 3, and finally the rod-shaped blank 10 is cut as a whole.

[0028] The size of the cutting blade 4 of the first cutting mechanism 1, the second cutting mechanism 2 and the third cutting mechanism 3 is consistent.

[0029] The driving motor 5 is correspondingly arranged on both sides of each cutting blade 4 of the first cutting mechanism 1, the second cutting mechanism 2 and the third cutting mechanism 3, and the driving motors 5 on both sides of the cutting blade 4 move synchronously.

The electric clamping jaws 9 on both sides of the lifting plate 8 have the functions of automatic clamping and fixing, and the rod-shaped blank 10 is clamped from both sides.

[0031] The width of the lifting plate 8 and the width of the cutting gap 6 are correspondingly set. When the rod-shaped blank 10 moves downward and the two sides of the rod-shaped blank 10 are cut, the cutting blade 4 will not cut the lifting plate 8 above the cutting blade.

[0032] The upwardly protruding accommodation groove 11 is further arranged on the lifting plate 8, and the accommodation groove 11 is located directly above the cutting gap 6. When the cutting blade 4 of the third cutting mechanism 3 cuts the rod-shaped blank 10, the cutting blade 4 of the third cutting mechanism 3 correspondingly extends into the accommodation groove 11.
