Abstract
A polishing head that can be disassembled and comprises a polishing cloth 1, sponge 2 and plastic base 3. The polishing cloth 1 is tightly pressed on the plastic base 3 by a sponge 2. The plastic base 3 is divided into one part with male threads and the other part with female threads. The two parts coordinate with each other to achieve dismantling or locking of the cloth and sponge to the base. When the polishing cloth is damaged, the plastic base can be unscrewed to change the damaged polishing cloth, while the base can be reused so as to reduce waste.
