Abstract
The utility model relates to an oral cavity polishing and glaze-removing instrument which comprises a holding rod, a fastener and a polishing and glaze-removing cutter group, due to the arrangement of the fastening piece, a firm matching relation is formed between the dull polish piece and the holding rod, when the rotary pressing barrel is matched with the thread matching part in an overlapped mode, the contact degree of the inclined wall face and the pressing piece is gradually improved, and therefore the pressing force is improved; due to the arrangement of the positioning bulge and the positioning recess, the frosted sheet is more tightly matched with the holding rod, and a user can conveniently realize quick matching at a general degree, namely, position determination is better realized; the fastening pieces, the positioning protrusions and the positioning recesses are used in cooperation, so that firmness of the frosted sheet is improved, meanwhile, the frosted sheet is easy to disassemble and convenient to operate, and working efficiency is improved.
