Fast detachable polishing plate mechanism

Abstract

The present invention provides a fast detachable polishing plate mechanism. The fast detachable polishing plate mechanism includes a polishing plate and a rod. The polishing plate has an adhesion unit disposed on the lower surface of the polishing plate. The rod connects straightly to the upper surface of the polishing plate. The rod is divided into an upper section, a middle section and a lower section from top to bottom, and only the middle section has a thread. The present invention further provides a hand-held machine tool having a drive shaft. The drive shaft has a tapped hole. The fast detachable polishing plate mechanism is mounted to the hand-held machine tool through the rod being inserted to the tapped hole.

What is claimed is: 
     
         1 . A fast detachable polishing plate mechanism, comprising:
 a polishing plate having an adhesion unit disposed on a lower surface thereof; and   a rod connected straightly to an upper surface of the polishing plate, wherein the rod is divided into an upper section, a middle section and a lower section from top to bottom, and only the middle section has a thread.   
     
     
         2 . The fast detachable polishing plate mechanism of  claim 1 , further comprising a grinding unit fixed to the lower surface of the polishing plate through the adhesion unit. 
     
     
         3 . The fast detachable polishing plate mechanism of  claim 2 , wherein the grinding unit includes a sponge or a sandpaper. 
     
     
         4 . The fast detachable polishing plate mechanism of  claim 1 , wherein the adhesion unit includes a touch fastener. 
     
     
         5 . The fast detachable polishing plate mechanism of  claim 1 , wherein the end face of the upper section of the rod is cylindrical, spherical, chamfered or tapered. 
     
     
         6 . A hand-held machine tool, including:
 the fast detachable polishing plate mechanism of any one of  claim 1 ; and   a drive shaft having a tapped hole used for jointing to the rod of the fast detachable polishing plate mechanism.
