发明名称 Golf training device
摘要 A golf swing training apparatus has a flat base for supporting a tee. A target line is marked on the base, through the tee location. To guide the correct swing of a driver, a foam block is positioned on the base on the side of the target line opposite the golfer. The block normally converges towards the target line on the back side of the tee to guide the club head along an inside out trajectory as it approaches the ball. To accommodate the proper backswing, which should follow an inside out trajectory, the guide block is pivotally mounted to pivot about an upright axis to one side of the tee on the base and is resiliently biased to its normal position so that the backswing will swing the guide block out of the way during the backswing.
