The housing 901 and the enclosing plate 902 are fixedly connected by a plurality of bolts and nuts. The housing 901 is inlaid with a rotary motor 903 fixedly positioned relative to the housing 901. The output shaft of the rotary motor 903 is coaxially fixedly connected with a first gear 904, and the first gear 904 is engaged with a second gear 905. The first gear 904 and the second gear 905 are only in a transmission relationship, without a fixed transmission ratio. The second gear 905 is coaxially fixedly penetrated with a polishing seat 907, and the bottom opening of the polishing seat 907 is threadedly connected with a polishing disc 908.
