The base 1 and the pressing plate 2 limit the up-and-down moving distance of the floating plate 17, and the up-and-down movement is avoided so as to keep stable. The upper end surface and the lower end surface of the floating plate 17 are correspondingly provided with an upper ball groove 21 and a lower ball groove 22, the upper ball groove 21 and the lower ball groove 22 are annular grooves, the diameters of the upper ball groove 21 and the lower ball groove 22 can be the same or different, a plurality of balls 23 are placed in the upper ball groove 21 and the lower ball groove 22, the plurality of balls 23 installed in the upper ball groove 21 and the lower ball groove 22 are correspondingly in rolling contact with the upper end plane of the accommodating cavity 14 and the upper end plane of the floating plate 17, the floating plate 17 can slide along the plane between the base and the pressing plate 2, the floating plate further comprises a circular connecting plate 24 installed at the lower end of the pressing plate 2, the connecting plate 24 is used for being connected and fixed with a cylinder body 28 of a finger cylinder 27, a connecting shaft 25 is arranged in the middle of the upper end of the connecting plate 24, and the connecting shaft 25 is inserted into the hollow lower shaft 20 after passing through the pressing plate through hole 4.

In some embodiments, a conical hole 29 is formed in the hollow lower shaft 20, the connecting shaft 25 is a cone matched with the conical hole 29, the connecting shaft 25 is inserted into the conical hole 29, and the connecting shaft 25 and the conical hole 29 are connected in a conical surface fit manner, so that the installation and the disassembly are convenient. Specifically, the base 1 and the pressing plate 2 and the connecting plate 24 are respectively fixed together by a plurality of fasteners 26 distributed regularly, and the fasteners 26 can be screws, bolts or threaded connectors such as screws.

When in use, the base 1 is fixedly connected with the connecting block 6 of the vibration device 5 through bolts, and the connecting plate 24 is fixedly connected with the cylinder body 28 of the finger cylinder 27 through bolts. The finger cylinder 27 holds the gallipot cover so that the outer wall of the lower end of the gallipot cover contacts the inner wall of the opening of the gallipot. Because the gallipot is driven by the motor to rotate, when the gallipot rotates, the inner wall of the opening part of the gallipot and the outer wall of the lower end of the gallipot cover are ground, and finally the effects of smooth contact surface and good laminating degree are achieved. When there is a bulge at a certain place of the inner wall of the mouth of the gallipot, the resistance at the place becomes large. When the resistance becomes large, the terrine cover can move in the other direction by itself, because the floating plate 17 adopts a floating structure design, and can freely move along the plane. Specifically, because the ceramic pot cover is clamped by the finger cylinder 27, the finger cylinder 27 is fixed with the connecting plate 24 of the floating device, the connecting shaft 25 arranged in the middle of the upper end of the connecting plate 24 passes through the pressing plate through hole 4 and then is inserted into the hollow lower shaft 20, and the floating plate 17 can relatively slide between the base 1 and the pressing plate 2 through the plurality of balls 23 arranged in the upper ball groove 21 and the lower ball groove 22. Therefore, when the resistance becomes large, the gallipot cover slightly moves towards the other direction, so that the self-adaption between the gallipot cover and the gallipot opening is realized, the contact force between the gallipot cover and the gallipot opening is kept relatively balanced, and the grinding effect is ensured. When the resistance is reduced, the elastic ring 16 forces the floating plate 17 to reset, and the finger cylinder 27 and the ceramic pot cover are synchronously and automatically reset.
