[0027] For details, please refer to the attached Figure 2 A groove is provided at the rear side of the processing table 10, and an adjustment mechanism 30 is installed at the rear side of the processing table 10. The adjustment mechanism 30 includes a bidirectional screw rod 32 rotatably connected and installed in the groove, a driving motor 31 installed on one side of the bidirectional screw rod 32, a movable block 33 symmetrically installed on the bidirectional screw rod 32, and an F-type connecting frame 34 respectively installed on the top of the two movable blocks 33, and the F-type connecting frame 34 is connected to one side of the L-shaped placement plate 21;

[0028] In this embodiment, it should be noted that the bidirectional screw rod 32 can be rotated by driving the motor 31, so that the two movable blocks 33 are moved closer to or farther from each other, thereby adjusting the distance between the two clamping mechanisms 20, thereby being used to fix optical glasses of different sizes and increasing applicability.
