Baseball bat

Abstract

This utility model discloses a type of baseball bat that falls within the baseball paraphernalia and is composed of a hitting part and a handle part; the inside of the hitting part is a hollow cavity, and the hitting—part wall body is of unequal wall-thickness construction. Different sections of the hitting part may hit the baseball when hitting. The wall body of hitting part is of an unequal wall-thickness construction, therefore, different resilience effect may be achieved by the hitting part with different wall thickness, the hitting effect of each stroke is different, and the pitch of baseball achieved by baseball bat makes it hard for an attacker to catch the baseball.

What is claimed is: 
     
         1 . A kind of baseball bat composed of a hitting part and a handle part, with a hollow-cavity inside the hitting part, characterized in that the wall body of the hitting part is of an unequal wall-thickness construction. 
     
     
         2 . A kind of baseball bat as described in  claim 1 , characterized in that the hollow cavity of hitting part has an elliptic, polygonal or irregular cross-section. 
     
     
         3 . A kind of baseball bat as described in  claim 2 , characterized in that the hitting part is fitted with a sheathcoat. 
     
     
         4 . A kind of baseball bat as described in  claim 1 ,  2  or  3 , characterized in that the hitting part and handle part may be of one-piece construction. 
     
     
         5 . A kind of baseball bat as described in  claim 1 ,  2  or  3 , characterized in that the hitting part and handle part also may not be of one-piece construction; the front end of handle part is fitted with a connecting shaft, and the hitting part is interference-fit connected to the connecting shaft such that the hitting part is fitted to the front end of the handle part. 
     
     
         6 . A kind of baseball bat as described in  claim 5 , characterized in that the connection of the connecting shaft and the hitting part is reinforced with adhesive.
