Light is refracted and reflected through its surface to form an image. Transmission materials are divided into three categories: optical glass, optical crystal and optical plastic, among which optical glass is the most commonly used optical material. In recent years, with the widespread use of optical instruments, the demand for optical elements has gradually increased, especially the demand for high-precision optical lenses has increased linearly. When processing optical lenses, it is necessary to first fix the lens in the chassis, and then polish the lens surface with polishing equipment.

[0023] By installing a rotatable bidirectional screw 5 inside the movable base 3, when the optical lens needs to be processed, the optical lens is first placed in the middle of the movable base 3, and then the stepper motor 6 can be started to rotate the bidirectional screw 5, and the two groups of threaded sleeves 7 outside the bidirectional screw 5 can drive the two groups of mounting seats 10 to move towards each other under the guidance of the threads and the guide slider 9, so that the splints 11 on the two groups of mounting seats 10 can be quickly moved to both sides of the optical lens to stably clamp the optical lens, and the splints 11 can be quickly connected to the mounting seat 10 through the positioning plug rod 12, so that the splints 11 can be quickly replaced according to the size of the optical lens, and different types of splints 11 can be quickly installed on the mounting seat 10, thereby playing a role in stably clamping optical lenses of different sizes, effectively improving the convenience of the device when used.

[0024] In other embodiments, the locking assembly includes a movable groove 14 provided on the mounting seat 10, a movable block 15 slidably connected to the movable groove 14, a limit rod 16 fixed to the left and right sides of the movable block 15, and a pull handle 18;
