发明名称 Golf practice device
摘要 A golf practice device for a player to improve the player's swing of a golf club by striking a practice golf ball and observing the controlled movement of the practice golf ball. The device includes a base, an inverted L-shaped support having a horizontal portion and a mechanism for suspending the practice golf ball from the support. A member rotatable about a horizontal axis is mounted on the horizontal portion. A connecting bar has a first end swivelably attached to the rotatable member and a second end which extends downwardly from the rotatable member. The second end of the connecting bar extends through an opening in the practice golf ball and is attached to the ball. The length of the connecting bar which extends into the practice golf ball is adjustable so that the height of the ball from the base may be varied.
