[0030] The working principle of this utility model is as follows.

[0031] (a) Before operation, the first positioning block 414 and the rotating shaft 404 are connected together by the first positioning bolt 415. Then, the rotating shaft 404 and the second positioning block 417 are connected together by the second positioning bolt 418. Then, the spiral shaft 402 is rotated, and the moving plate 403 is driven to slide along the inner wall of the first mounting bracket 401 by the spiral shaft 402. Then, the rotating shaft 404 is driven to move by the moving plate 403. The rotating shaft 404 clamps the crystal 3 by the clamping plate 406.

[0032] (ii) The motor 505 starts, and the motor 505 drives the second gear 504 to rotate through the first gear 503. The second gear 504 drives the clamping plate 406 to rotate through the rotating shaft 404. The clamping plate 406 drives the crystal 3 to rotate. When the crystal 3 rotates, it is polished through the polishing shaft 407. The polished debris falls into the collection box 2 through the square hole 103.

[0033] (III) When the motor 505 starts, it drives the turntable 501 to rotate. The turntable 501 drives the first connecting rod 507 to move through the first connecting shaft 502. The first connecting rod 507 drives the vertical shaft 508 to move up and down. The vertical shaft 508 drives the second connecting rod 511 to move through the second connecting shaft 510. The second connecting rod 511 drives the driving block 513 to move through the third connecting shaft 512. The driving block 513 drives the push plate 509 to slide along the push plate 509, thereby pushing the debris ground down in the collection box 2 to complete the collection and facilitate the final cleaning.
