The present disclosure relates to a golf putting practice apparatus, and more particularly, to a golf putting practice apparatus in which the adjustment of the putting distance and the difficulty of putting are independently changed.

Golf is a sport game in which a golf ball is put into a hole cup by using a club on the green (G).

Golf is, like any sport, a sport that absolutely requires stable posture and repetitive training.

Representative techniques for good golf include swinging and putting. The swing is the direction of movement of the golf ball, the body movement during the swing, the central axis of the body during the swing, the goal setting during the swing, and the swing tempo. And a blow technique in consideration of the force distribution, and the like, using a centrifugal force according to the head weight of the club.

Putting is to put the golf ball into the hole cup at a distance close to the hole cup, and the direction setting according to the state and shape of the green (G) on the various shapes of the green (G), and the blow strength indicating the speed of the golf ball. Judgment corresponds to a finish action of golf putting a golf ball into a hole cup.

Conventionally, one of golfer's practice methods for putting practice is the practice of using coins. This is a method of practicing the putting operation such as the golfer's posture correction or the distribution of the force according to the moving speed of the golf ball by putting the coin on a certain distance of the virtual green G and performing the repeated putting operation. More specifically, as a training method for distributing the force at the time of putting the coin on the virtual green (G) during the putting practice and hitting the golf ball out of a certain distance to approach the coin, the golfers can When you hit, you'll repeat the exercise so that the golf ball doesn't go over 17 inches past the coin.

As mentioned above, the putting has another important technical factor of force distribution in addition to the importance of the direction, so the direction and speed of the wind passing on the green (G) and the degree of inclination of the green (G) when putting are included. In combination, the golf ball's direction and force distribution should be adjusted.

As a conventional putting exerciser, Korean Laid-Open Patent Publication No. 2001-44509 is known. Patent Publication No. 2001-44509 "Golf Putting Practice Device" installs hydraulically operated hydraulic cylinders at equal intervals on the bottom of a wide green (G) section made of artificial grass, and draws the rods of the respective hydraulic cylinders (G).
