Adjustable Batting Apparatus

Abstract

An adjustable batting apparatus contains a spring, at least one batting pad, a belt, and a rolling device. The spring is cylindrical and including a plurality of coils, a first segment, a second segment, and the first segment is fixed on a fixing face of a base. The at least one batting pad is connected with the second segment. The belt has a first end coupled with the second segment of the spring and has a second end. The rolling device has the second end of the belt rolled therearound, and a part of the belt extends out of the rolling device so as to form an extending section, such that the rolling device controls a length of the extending section of the belt so as to adjust a distance between the plurality of coils of the spring, hence a bending flexibility of the spring is adjusted.

What is claimed is: 
     
         1 . An adjustable batting apparatus comprising:
 a spring being cylindrical and including a plurality of coils, a first segment, a second segment, and the first segment of the spring being fixed on a fixing face;   at least one batting pad connected with the second segment of the spring;   a belt having a first end and a second end, and the first end being coupled with the second segment of the spring; and   a rolling device having the second end of the belt rolled therearound, and a part of the belt extending out of the rolling device so as to form an extending section, such that the rolling device controls a length of the extending section of the belt so as to adjust a distance between the plurality of coils of the spring, hence a bending flexibility of the spring is adjusted.   
     
     
         2 . The adjustable batting apparatus as claimed in  claim 1  further comprising a base including the fixing face defined on a top surface thereof so as to fix the first segment of the spring. 
     
     
         3 . The adjustable batting apparatus as claimed in  claim 2 , wherein the base includes a wheel set disposed on an outer side thereof adjacent to a bottom end of the base. 
     
     
         4 . The adjustable batting apparatus as claimed in  claim 2 , wherein the base includes a recessed portion formed on the top surface thereof so as to fix the rolling device. 
     
     
         5 . The adjustable batting apparatus as claimed in  claim 1 , wherein the spring includes a first positioning piece fixed on the first segment, and the first positioning piece has a first horizontal bar for fixing the first segment of the spring on the fixing face of the base by ways of the first positioning piece. 
     
     
         6 . The adjustable batting apparatus as claimed in  claim 1 , wherein the spring has a second positioning piece mounted on the second segment thereof, and the second positioning piece has a second horizontal bar secured thereon, the batting pad is connected with the second segment of the spring by using the second positioning piece. 
     
     
         7 . The adjustable batting apparatus as claimed in  claim 1 , wherein the spring is screwed with the at least one batting pad. 
     
     
         8 . The adjustable batting apparatus as claimed in  claim 6 , wherein the second positioning piece of the second segment of the spring has outer threads arranged around an outer peripheral side thereof so as to screw with inner threads of a socket of the batting pad, such that the spring is screwed with the batting pad. 
     
     
         9 . The adjustable batting apparatus as claimed in  claim 1 , wherein the rolling device is a hand puller fixed on the recessed portion of the base. 
     
     
         10 . The adjustable batting apparatus as claimed in  claim 1 , wherein the spring had a protective sleeve fitted thereon so as to protect the spring.
