Please refer to Fig. 1 to Fig. 3, a kind of abrasive brush 100 that this utility model embodiment provides, it is installed up in polisher (not shown) and deals with so that workpiece to carry out deburring or polishing knife mark. Abrasive brush 100 includes pedestal 10 and the plurality of bristles 20 being arranged on pedestal 10. Pedestal 10 includes body 11 and the stud 12 being fixed on body 11. Body 11 is substantially in the form of annular discs, and it includes first surface 111 and the second surface 112 relative with first surface 111, and stud 12 is vertically connected at the first surface 111 of body 11, and plurality of bristles 20 is respectively fixedly connected with the second surface 112 in body 11. Stud 12 is generally cylindrical, and its perisporium is provided with threaded portion 121 for the screwed hole (not shown) on adaptive polisher, in order to abrasive brush 100 be fixedly connected on this polisher.

The connected mode being appreciated that between abrasive brush 100 and this polisher is not limited merely in the present embodiment to utilize the screw connection manner of stud 12.In other embodiments, may be used without the connector of manner between abrasive brush 100 and this polisher. But it is not limited to this, as long as this connector is easy to be stably connected with to this polisher abrasive brush 100.

Body 11 also includes one substantially in circular pad 113, it is sheathed on stud 12 and fixes with first surface 111 and is connected, pad 113 is for being connected to the outer rim of this polisher upper screwed hole, to prevent stud 12 not to be screwed into completely in this screwed hole, in turn result in the phenomenon that abrasive brush 100 occurs to loosen.
