Annular hardware fitting polisher

The utility model provides an annular hardware fitting polisher which comprises a base, one side of the base is connected with a supporting frame, and the supporting frame is connected with a liftable polishing mechanism. A first motor and a first bearing seat are fixedly connected to the base, a second bearing seat is further slidably connected to the base, the output end of the first motor is connected with a rotating rod used for being sleeved with the annular hardware, one end of the rotating rod is rotatably connected with the first bearing seat, and the other end of the rotating rod is movably connected into the second bearing seat. The second bearing seat can be separated from the rotating rod, so that sleeving of the annular hardware is facilitated; a limiting hole is formed in the side, close to the second bearing seat, of the rotating rod, and a limiting block used for clamping the annular hardware is inserted into the limiting hole. The polishing mechanism is located over the rotating rod so that t
