Assembly joint structure of a long handle and a scraper top for a scraping tool

Abstract

The invention is related to an assembly joint structure of a long handle and a scraper top for a scraping tool. In general, it contains a long handle for hand grip and a scraper top in the front. In the invention, the rear central section of the scraper top has a connecting column of suitable length. On the connecting column, there are two through holes. In the front of the long handle, there is a connecting hole that has the same inner diameter as the outer diameter of the connecting column. On the wall of the connecting hole there are corresponding through holes. When the scraper top inserts the connecting column into the connecting hole of the long handle, rivets can be put in the through holes to constitute an assembly joint structure between the long handle and the scraper top.

1 . An assembly joint structure for a long handle and a scraper top of a scraping tool contains a long handle and a scraper top in the front with characteristics described as follows:
 the rear central section of the scraper top forms a connecting column of suitable length and on the connecting column there are two through holes;   in the front of the long handle, there is a connecting hole of the same diameter as the outer diameter of the connecting column and on the wall of the connecting hole there are corresponding through holes;   the scraper top inserts the rear connecting column into the connecting hole in the front of the long handle and rivets are put in the through holes to constitute an assembly joint structure for a long handle and a scraper top.   
     
     
         2 . As described in  claim 1  for an assembly joint structure for a long handle and a scraper top of a scraping tool, the rivet can be any type of fixture. 
     
     
         3 . As described in  claim 1  for an assembly joint structure for a long handle and a scraper top of a scraping tool, the outer diameter of the connecting column in the rear of the scraper top is equal to the inner diameter of the connecting hole in the front of the long handle.
