Swinging tee

Abstract

A batting tee for baseball is comprised of a base, a height adjustable post erected on the base, a mechanical box containing a swing mechanism and a return mechanism being disposed at the top of the post, a rod being axially erected from one side of the swing mechanical box, a baseball being connected to the top of the rod; a swing for a preset angle being achieved when the baseball is stricken; the baseball returning to its standby position for next swing practice without spinning for 360° to pay better efficiency and results of swing practice by eliminating the return problem of the prior art.

1 . A swinging tee for baseball is comprised of a base, a post in proper height being erected at the center of the base, a mechanical box containing a swing mechanism and a return mechanism interconnected to each other being disposed at the top of the post, a rod being erected and connect to the swing mechanism, and a baseball being disposed on the tope of the rod.  
   
   
       2 . The swinging tee for baseball of  claim 1 , wherein the swing mechanism relates to a turntable, an axial hole being disposed at the center of the turntable, the rod being inserted into the axial hole and connected to the turntable; a pin being disposed at where pre-designated on the inner circumference of the turntable, the return mechanism being related to a coil, one end of the coil being hooked to the pin of the turntable to connect the coil to the turntable, and both of the turntable and the rod being enabled with automatic return efficacy.  
   
   
       3 . The swinging tee for baseball of  claim 1 , wherein the return mechanism relates to a resilient rubber stick.  
   
   
       4 . The swinging tee for baseball of  claim 1 , wherein the return mechanism relates to a vortex spring disposed to the axial of the swing mechanism.  
   
   
       5 . The swinging tee for baseball of  claim 1 , wherein the return mechanism relates to a spring in lieu of a rotation mechanism, the spring being directly hooked to where between the rod and the mechanical box to achieve the same automatic return purpose of the rod.  
   
   
       6 . The swinging tee for baseball of  claim 1 , wherein the return mechanism relates to a spring, one end of the spring being hooked to the swing mechanism, another end of the spring being hooked to an adjustment bolt to adjust the tension of the spring.  
   
   
       7 . The swinging tee for baseball of  claim 1 , wherein a limiting lever is disposed on one side of the mechanical box to limit the swing angle of the rod.  
   
   
       8 . The swinging tee for baseball of  claim 1 , wherein the base is made hollow to be filled up with water or sandstone as a weight.  
   
   
       9 . The swinging tee for baseball of  claim 1 , wherein the post is comprised of an inner tube inserted into an outer tube, and a fastener is provided for height adjustment of the post.
