[0027] Furthermore, a motor 151 is fixedly provided in the fixed box 15, and the output shaft of the motor 151 passes through the fixed box 15 and is fixedly connected to the C-shaped block 152. A circular groove 2 is provided at the bottom of the fixed box 15, and the output shaft of the motor 151 passes through the circular groove 2 to facilitate the rotation of the C-shaped block 152.

[0028] Furthermore, a second motor 1521 is fixedly provided on one side of the C-shaped block 152 , and an output shaft of the second motor 1521 passes through the C-shaped block 152 and is fixedly connected to the L-shaped plate 153 , so as to facilitate the rotation of the L-shaped plate 153 .

[0029] Furthermore, the output shaft of the motor 154 is fixed with a fixing plate 155, and one side of the polishing plate 157 is fixed with symmetrical fixing bolts 156, and the fixing bolts 156 are threadedly connected to the fixing plate 155. A circular groove 1 is opened on one side of the L-shaped plate 153, and the output shaft of the motor 154 passes through the circular groove 1, so as to facilitate the rotation of the fixing plate 155 and the polishing plate 157.
