Abstract

The present invention relates to a golf club reference system having improved performance in accurate hitting of a golf ball by providing the most ideal, accurate angle of a golf club at a starting point, by matching a lie angle and a socket angle when addressing. The golf club reference system of the present invention installed on a hosel installed on a club head having a hitting surface or a shaft having a handle formed in an upper portion and connected to the hosel in an lower portion, the reference system comprising: a fixing ring surrounding the hosel or the shaft, a fixing screw shaft protruding from the fixing ring in one direction; a fixing nut fixing the fixing screw shaft; a display part connected to the fixing ring through a bridge, and a color crosshair formed on an upper portion of the display part.

What is claimed is: 
     
         1 . A golf club reference system installed on any one of a hosel  12  or a shaft  13 , wherein the hosel  12  is installed on a club head  10  having a hitting surface  11  that is formed below the shaft  13  having a handle  14  formed in an upper portion thereof, wherein an inside of the hosel  12  is connected to the shaft  13  upward, the golf club reference system comprising:
 a fixing ring  21  surrounding any one of the hosel  12  and the shaft  13 , 
 a fixing screw shaft  24  protruding from the fixing ring  21  in one direction; 
 a fixing nut  40  fixing the fixing screw shaft  24 ; 
 a display part  30  connected to the fixing ring  21  through a bridge  26 , and 
 a color crosshair  31  formed on an upper portion of the display part  30 . 
 
     
     
         2 . The golf club reference system of  claim 1 , wherein the fixing ring  21  includes a cutout portion  23  formed in one direction, and the fixing screw shaft  24  respectively protrudes from each of ends of the fixing ring  21  that are separated from each other by the cutout portion  23 . 
     
     
         3 . The golf club reference system of  claim 1 , wherein rotation preventing protrusions  22  are installed to protrude on an inner circumference of the fixing ring  21  at regular intervals to prevent the fixing ring  21  from rotating. 
     
     
         4 . The golf club reference system of  claim 1 , wherein the fixing ring  21  includes a reference alignment part  25  formed on a center of an upper portion thereof to guide an installation position accurately. 
     
     
         5 . The golf club reference system of  claim 1 , wherein the display part  30  is formed in a cylindrical shape. 
     
     
         6 . The golf club reference system of  claim 1 , wherein a set of the fixing ring  21 , the bridge  26 , and the display part  30  is formed to be separated into a first and a second member  60 ,  65 ,
 wherein fusion surfaces  50 ,  55  of the first and the second member  60 ,  65  of the fixing ring  21 , the bridge  26 , and the display part  30 , fusion to form one body of the fixing ring  21 , the bridge  26 , and the display part.
