Pendulum putting trainer

Abstract

A pendulum putting trainer, comprising: a main shaft provided with a handle at one end thereof and a putter head at the other end thereof, the putter head having a striking face and a non-striking face opposite to the striking face; and an auxiliary shaft having a first shaft portion provided with an abutting member at an upper end thereof and a second shaft portion provided with a joining member that connects with the non-striking side of the putter head of the main shaft at a lower end thereof, the auxiliary shaft being arranged obliquely such that it has an included angle with respect to the main shaft; wherein a connecting member is disposed at a location where the first shaft portion and the second shaft portion are connected; and wherein the first shaft portion is hollow and the second shaft portion can move relatively within the first shaft portion and the connecting element, so that a length of the auxiliary shaft can be adjusted to make the auxiliary shaft abut against the user and thereby to help the user maintain a good putting stance.

What is claimed is: 
     
         1 . A pendulum putting trainer, comprising:
 a main shaft provided with a handle at one end thereof and a putter head at the other end thereof, the putter head having a striking face and a non-striking side opposite to the striking face; and   an auxiliary shaft having a first shaft portion provided with an abutting member at an upper end thereof and a second shaft portion provided with a joining member that connects with the non-striking side of the putter head of the main shaft at a lower end thereof, the auxiliary shaft being arranged obliquely such that it has an included angle with respect to the main shaft;   wherein a connecting element is disposed at a location where the first shaft portion and the second shaft portion are connected; and wherein the first shaft portion is hollow and the second shaft portion can move relatively within the first shaft portion and the connecting element, thereby a length of the auxiliary shaft can be adjusted.   
     
     
         2 . The pendulum putting trainer according to  claim 1 , wherein a screw having external threads is formed at an upper end of the second shaft portion of the auxiliary shaft and mates with a movable locking fastener having internal threads. 
     
     
         3 . The pendulum putting trainer according to  claim 2 , wherein the connecting element can abut against the movable locking fastener and thereby to prevent the second shaft portion from separating from the first shaft portion downwardly. 
     
     
         4 . The pendulum putting trainer according to  claim 1 , wherein clockwise or counterclockwise rotation of the first shaft portion enables the first shaft portion to secure or release the second shaft portion, thereby a combined length of the first shaft portion and the second shaft portion can be adjusted. 
     
     
         5 . The pendulum putting trainer according to  claim 1 , wherein the joining member of the second shaft portion of the auxiliary shaft is provided with a magnetic element so as to magnetically attach to the putter head of the main shaft. 
     
     
         6 . The pendulum putting trainer according to  claim 5 , wherein the magnetic element is provided at a side wall of the joining member close to the non-striking side of the putter head. 
     
     
         7 . The pendulum putting trainer according to  claim 5 , wherein the magnetic element is provided at a bottom of the joining member. 
     
     
         8 . The pendulum putting trainer according to  claim 1 , wherein the abutting member of the first shaft portion has a soft material. 
     
     
         9 . The pendulum putting trainer according to  claim 1 , wherein the main shaft has an inclination greater than that of the auxiliary shaft.
