发明名称 Golf club swing training device
摘要 A golf practice aid having a pair of upstanding converging side walls and a top extending outwardly over the converging side walls. This structure forms an outwardly open golf head tunnel or passageway. In use, the ball is set just outside the exiting end of the tunnel and the golfer is required to swing the golf club head under the top and adjacent the converging side walls of the practice aid before the club impacts the ball. This requires the golfer to maintain a proper stance in order to maintain eye contact with the ball and further requires the golfer to swing down and under the ball and to maintain the path of the golf club in line with the proper flight of the ball.
