Abstract

The present disclosure provides a polishing tool, and relates to the technical field of cosmetic instruments. The polishing tool comprises a driving structure, a polishing head, a protective piece, an adjusting piece and a detecting piece. The polishing head is connected with the driving structure and rotates under the driving of the driving structure. The protective piece comprises a containing cavity, and the polishing head extends in the containing cavity. The adjusting piece is connected with the driving structure and is used for controlling the movement of the driving structure based on the thickness of the object to be polished, so as to adjust the length of the end of the polishing head away from the driving structure extending out of the containing cavity in the direction of the rotation axis of the polishing head. The detecting piece is arranged on the protective piece and is used for sending a stop signal to the driving structure when the protective piece is detected to be in contact with the object to be polished, so that the driving structure controls the polishing head to stop rotating.
