Practice golf putter

Abstract

A practice golf putter includes a body formed to hit a golf ball, the body having a concave portion, which is formed on the front of the body and is open at the front and on the top thereof. The concave portion includes inclined surfaces formed on the left and right sides thereof; and a protrusion formed at a lower end portion of a point at which the inclined surfaces meet, and protruding toward the front. Therefore, the golf putter has the following effects. Since a striking point can be known through the advancing trajectory of the golf ball when the golf ball is struck by a practice golf putter, the location of the practice golf putter can be changed as needed, thereby enabling correct swing stances to be mastered. Therefore, putting can be more quickly learned than when using a conventional technology.

1 . A practice golf putter including a body configured to hit a golf ball, the practice golf putter comprising:
 a concave portion formed on a front surface of the body and opened forward and upward, wherein   the concave portion includes inclined surfaces formed on left and right sides of the concave portion, and a protrusion formed at a lower end portion of a point at which the inclined surfaces meet each other, and protruding forward.   
     
     
         2 . A practice golf putter including a body configured to hit a golf ball, the practice golf putter comprising:
 an insertion groove formed on a front surface of the body and opened forward, upward and downward;   a T-shape key slot formed rearward from the insertion groove and perforated in a vertical direction; and   a concave hitting portion provided at a rear side thereof with a T-shape key inserted into the key slot, and inserted into the insertion groove to hit the golf ball, wherein   the concave hitting portion includes a concave part formed on a front surface of the concave hitting portion and opened forward and upward, in which the concave part includes inclined surfaces formed on left and right sides of the concave part, and a protrusion formed at a lower end portion of a point at which the inclined surfaces meet each other, and protruding forward.   
     
     
         3 . The practice golf putter of  claim 2 , further comprising:
 a tap hole perforated from a rear side of the body toward the key slot; and   a ball plunger fastened to the tap hole to pressurize the key.   
     
     
         4 . The practice golf putter of  claim 2 , further comprising:
 a real hitting portion having a flat front surface, formed at a rear side thereof with a T-shape key inserted into the key groove, and inserted into the insertion groove to hit the golf ball.   
     
     
         5 . The practice golf putter of  claim 4 , further comprising: an elastic part attached to the front surface of the real hitting portion. 
     
     
         6 . The practice golf putter of  claim 5 , wherein the elastic part includes a tube filled with air. 
     
     
         7 . The practice golf putter of  claim 3 , further comprising:
 a real hitting portion having a flat front surface, formed at a rear side thereof with a T-shape key inserted into the key groove, and inserted into the insertion groove to hit the golf ball.
