Adjustable Batting Apparatus

Abstract

An adjustable batting apparatus contains a spring, at least one batting pad, a screw rod, and a nut. The spring is cylindrical and includes a plurality of coils, a first segment, a second segment, and the first segment or the second segment is fixed on a fixing face. The at least one batting pad is connected with the second segment or the first segment. The screw rod is axially inserted into the spring and having a first end coupled with the first segment of the spring and a second end extending out of the second segment of the spring so as to form an adjusting section. The nut screws with the adjusting section so that the nut is rotated to control a length of the adjusting section of the screw rod, hence the spring is pressed or released, thus adjusting a bending flexibility of the spring.

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 or the second segment of the spring being fixed on a fixing face;   at least one batting pad connected with the second segment or the first segment of the spring;   a screw rod axially inserted into the spring and having a first end and a second end, and the first end of the screw rod being coupled with the first segment of the spring, the second end of the screw rod extending out of the second segment of the spring so as to form an adjusting section;   a nut screwing with the adjusting section of the screw rod so that the nut is rotated to control a length of the adjusting section of the screw rod, hence the spring is pressed or released, thus adjusting a bending flexibility of the spring.   
     
     
         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 1 , wherein the spring includes a first positioning piece fixed on the first segment. 
     
     
         5 . 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 through orifice defined at a central position thereof, a diameter of the through orifice is larger than that of the screw rod. 
     
     
         6 . The adjustable batting apparatus as claimed in  claim 5 , wherein the second end of the screw rod extends out of the second segment of the spring via the through orifice of the second positioning piece so as to form an adjusting section. 
     
     
         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 5 , 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 nut matches with a washer to screw with the adjusting section of the screw rod. 
     
     
         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.
