Glue-removing wheel assembly and adapter thereof

Abstract

A glue-removing wheel assembly has an adapter, a reinforcing piece, and a wheel body. The adapter has a large diameter section, a small diameter section, and a connecting rod. The small diameter section is connected with the large diameter section and has a cross section being hexagonal and a necked segment disposed on an external surface of the small diameter section. The connecting rod is disposed on the large diameter section and is opposite to the small diameter section. The reinforcing piece is connected to the adapter and has an internal annular face disposed on the reinforcing piece and securely mounted around the connecting rod of the adapter and an external annular face. The wheel body is round, is coaxial with the adapter, and is mounted around the large diameter section of the adapter and the reinforcing piece.

What is claimed is: 
     
         1 . An adapter of a glue-removing wheel assembly being a rod body and comprising:
 two ends;   a large diameter section disposed on one of the two ends of the adapter and having
 an end face; and 
 a mounting segment axially formed through the end face of the large diameter section; and 
   a small diameter section disposed on the other one of the two ends of the adapter, being opposite to the end face of the large diameter section, connected to the large diameter section, and having
 a cross section being hexagonal; 
 an external surface; 
 a middle; and 
 a necked segment disposed on the external surface of the small diameter section at the middle of the small diameter section. 
   
     
     
         2 . The adapter as claimed in  claim 1 , wherein the large diameter section has
 an external surface; and   a holding segment disposed on the external surface of the large diameter section.   
     
     
         3 . A glue-removing wheel assembly comprising:
 an adapter having
 two ends; 
 a large diameter section disposed on one of the two ends of the adapter and having an end face; 
 a small diameter section disposed on the other one of the two ends of the adapter, being opposite to the end face of the large diameter section, connected to the large diameter section, and having
 a cross section being hexagonal; 
 an external surface; 
 a middle; and 
 a necked segment disposed on the external surface of the small diameter section at the middle of the small diameter section; and 
 
 a connecting rod axially formed on and protruding from the end face of the large diameter section and being opposite to the small diameter section; 
   a reinforcing piece connected to the adapter and having
 an internal annular face disposed on the reinforcing piece and securely mounted around the connecting rod of the adapter; and 
 an external annular face; and 
   a wheel body being round, being coaxial with the adapter, and mounted around the large diameter section of the adapter and the reinforcing piece.   
     
     
         4 . The glue-removing wheel assembly as claimed in  claim 3 , wherein the external annular face of the reinforcing piece is wavy.
