[0027] The specific implementation process of the utility model is as follows: when the device for cutting special-shaped optical lens blanks needs to be used, the special-shaped optical lens blanks are placed on the cutting table 2, and the motor 4 is started to drive the output shaft to rotate, so as to drive the screw 5 to rotate. Under the relationship of the threaded connection, the clamping plate 6 can be pushed down to clamp and fix the special-shaped optical lens blanks. In this process, when the clamping plate 6 moves, the inner wall of the clamping hole 7 squeezes the clamping ball 9 to push the clamping ball 9 to move, and drives the guide block 8 to move to ensure the stable movement of the clamping ball 9, and the spring 10 is deformed, so that the clamping ball 9 finally disengages from the clamping hole 7. Under the action of force, the clamping ball 9 slides along the inner wall of the fixing seat 3. When the clamping ball 9 slides into the next clamping hole 7, the spring 10 restores the deformation to push the clamping ball 9 to insert into the clamping hole 7, and the position of the clamping plate 6 is accurately controlled, so as to automatically and accurately clamp and use special-shaped optical lens blanks of different sizes;

Under the drive of the motor 14 and the cylinder 12, the drill 15 can be driven to rotate and move downward to cut the special-shaped optical lens blank.

[0029] During this process, when the motor 2 14 drives the drill bit 15 to rotate and move downward, the rotating member 16 also rotates and moves downward, and the rotating member 16 rotates along the surface of the limiting plate of the limiting member 17. Under the extrusion of force, the limiting member 17 can slide along the vertical part of the support frame 11 and drive the slider 18 to move to ensure the stable movement of the limiting member 17, and the spring 2 19 is deformed to ensure that the limiting plate of the limiting member 17 is always in contact with the rotating member 16, and the output end of the motor 2 14 is rotationally limited to avoid the centrifugal shaking of the drill bit 15.
