A plurality of evenly distributed arc grooves 23 are provided, and the right end of the cylindrical block 21 extends into one of the arc grooves 23. Through the mutual cooperation between the gear 8, the rectangular block 3, the first rack plate 6, the second rack plate 9, the positioning plate 13, etc., the two rectangular blocks 3 can be moved synchronously to achieve the purpose of being away from and approaching each other at the same time, which can effectively achieve its convenient use. A mounting groove 12 is provided at the bottom of the upper rectangular block 3, and a positioning plate 13 is provided in the mounting groove 12. Two first placement blocks 17 are fixedly connected to the bottom of the positioning plate 13, and two sliders are fixedly connected to the rear side wall of the positioning plate 13. Two slide grooves matching the sliders are provided on the rear wall of the inner cavity of the mounting groove 12. The bottom of the positioning plate 13 extends to the bottom of the rectangular block 3, and the top of the positioning plate 13 is fixedly connected to the first Spring 19, the top of the first spring 19 is fixedly connected to the mounting groove 12, a clamping plate 14 is movably connected between the front and rear inner walls of the mounting groove 12, and the rear side walls of the two clamping plates 14 are movably connected to the cross bars 16 near the positioning plate 13, and the opposite ends of the two cross bars 16 are fixedly connected to the positioning plate 13, respectively. A center positioning hole 24 is opened at the top of the rectangular block 3 located below, and a center positioning rod 25 is arranged in the center positioning hole 24, and the top of the center positioning rod 25 extends to the top of the rectangular block 3, and a rectangular groove 26 is opened on the front side wall of the rectangular block 3, and the rectangular groove 26 is connected to the inside of the center positioning hole 24, and an L-shaped rod 27 is arranged in the rectangular groove 26, and a third spring 28 is fixedly connected to the left side wall of the L-shaped rod 27, and the third spring 28 is fixedly connected to the rectangular groove 26,The right end of the L-shaped rod 27 extends into the center positioning hole 24 and contacts the center positioning rod 25.

Through the mutual cooperation between the positioning plate 13, the clamping plate 14, the cross bar 16, the center positioning rod 25, etc., the positioning plate 13 can be lifted up to drive the two clamping plates 14 downward to clamp the glasses and correct them to the middle. At the same time, the center positioning rod 25 fixes the center of the glasses, so as to achieve the purpose of positioning the glasses in the center, which can effectively improve its positioning effect.

[0022] Working principle: When using this technical solution, first place the bottom of the glasses between the upper and lower second placement blocks 18, pull the L-shaped rod 27 to the left to compress the third spring 28, so that the L-shaped rod 27 is not in contact with the center positioning rod 25, and drive the center positioning rod 25 upward to contact the middle of the glasses through the lever, and then release the L-shaped rod 27, and the third spring 28 pushes the L-shaped rod 27 to contact the center positioning rod 25, so that the center of the glasses can be fixed, and then the transmission rod 7 and the gear 8 are driven counterclockwise by the knob 11, and the gear 8 drives the first rack plate 6 and the second rack at the same time. The plates 9 move towards each other, so that the two rectangular blocks 3 move toward the middle at the same time. When the glasses are in contact with the positioning plate 13, the knob 11 is continued to be turned to make the two rectangular blocks 3 continue to move toward the middle, pushing the positioning plate 13 upward to compress the first spring 19. The positioning plate 13 synchronously drives the two cross bars 16 to rise, so that the two clamping plates 14 swing downward, so as to clamp and fix the two sides of the glasses, and at the same time, the glasses can be positioned in the center again, which can prevent the glasses from shaking and improve the center positioning effect. When the first rack plate 6 descends, the arc groove 23 makes the cylindrical block 21 move to the left to compress the second spring 22. After the glasses are fixed, the synchronous second spring 22 pushes the cylindrical block 21 into one of the arc grooves 23. This can prevent the first rack plate 6 from driving the gear 8 to reverse and prevent the two rectangular blocks 3 from loosening the glasses when measuring data. The above operation can achieve its convenient use.
