The top of the inner cavity of the square sleeve 4 is fixedly connected to a slide rod 17, and the movable plate 6 is slidably sleeved on the surface of the slide rod 17. By setting the slide rod 17, the movable plate 6 can be limited to avoid the movable plate 6 from moving overtravel and causing collision between components; the interior of the square sleeve 4 is fixedly connected to a bidirectional screw 5 through a bearing, and the right side of the square sleeve 4 is fixedly connected to a rubber Ring 19, the inner wall of the rubber ring 19 contacts the surface of the bidirectional screw 5. By providing the rubber ring 19, the friction between the square sleeve 4 and the bidirectional screw 5 can be increased, thereby improving the stability of the bidirectional screw 5 when it does not need to rotate; both sides of the surface of the bidirectional screw 5 are threadedly connected with a movable plate 6, and the right end of the bidirectional screw 5 is fixedly connected with a hexagonal plate 16. The top of the movable plate 6 contacts the top of the inner wall of the square sleeve 4. By providing the hexagonal plate 16, it is convenient for the user to rotate the bidirectional screw 5, avoiding the phenomenon that the user cannot effectively rotate the bidirectional screw 5; the inner sliding sleeve of the movable plate 6 is connected with an arc plate 1 7, the inner sliding sleeve of the arc plate 1 7 is connected with an arc plate 2 8, and the inner sliding sleeve of the arc plate 2 8 is connected with an arc plate 3 9;

[0033] Reference Figure 2-4 The front and back surfaces of the curved plate 1 7, the curved plate 2 8 and the curved plate 3 9 are all fixedly connected with sliders, and the interior of the movable plate 6, the curved plate 1 7 and the curved plate 2 8 are all provided with slide grooves, and the sliders are slidably connected to the interior of the slide grooves; both sides of the surface of the bidirectional screw 5 are threadedly connected with screw sleeves 20, and the side of the screw sleeve 20 close to the movable plate 6 is fixedly connected to the surface of the movable plate 6, which can increase the contact area between the bidirectional screw 5 and the movable plate 6, and avoid damage to the connection between the bidirectional screw 5 and the movable plate 6; the surface of the curved plate 3 9 is fixedly connected with a rubber pad 10, and the top of the left side of the support plate 2 is fixedly connected with a control device 11, and the top of the left side of the support plate 2 is hinged with a protective cover 15 by a hinge. The protective cover 15 is sleeved on the surface of the control device 11, and by setting the protective cover 15, the surface of the control device 11 can be protected to prevent foreign objects from colliding with the control device 11.

[0036] Working principle: The user first places the mineral sample inside the square sleeve 4, and then rotates the hexagonal plate 16. The hexagonal plate 16 drives the bidirectional screw 5 to rotate, and the bidirectional screw 5 drives the movable plate 6 to move. The movable plate 6 drives the arc plate 1 7 to move, and the arc plate 1 7 drives the arc plate 2 8 to move. The arc plate 2 8 drives the arc plate 3 9 to clamp the mineral sample. When the mineral sample is an irregular object, the arc plate 1 7, the arc plate 2 8 and the arc plate 3 9 will be adaptively rotated by the pressure of the bidirectional screw 5, so that the arc plate 3 9 can stably clamp the irregular mineral sample, and then start the polishing device 1, and then start the electric cylinder 3 through the control device 11. The electric cylinder 3 drives the mineral sample to move downward through the square sleeve 4, so that the polishing device 1 polishes the mineral sample, thereby achieving the effect of convenient and stable polishing.
