In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to propose a polishing grinding head. By dividing the grinding head handle into the first grinding head handle and the second grinding head handle, the utility model is convenient to make the first grinding head handle and the second grinding head handle into grinding head handles of different materials according to the different materials of the workpiece to be polished, which is convenient, flexible and environmentally friendly; In the process of polishing, through the buffer between the grinding head body and the first grinding head handle, the flexible contact between the grinding head body and the first grinding head handle is effectively prevented, which ensures a certain adaptive fine-tuning effect on the polishing angle and the contact surface of the workpiece to be polished, improves the polishing quality and enhances the aesthetics of polishing.
