Direction change structure of golf club head

Abstract

A direction change structure of golf club head includes a ferrule that is fit to a body of a club head for coupling a shaft of a golf club. The ferrule includes an eccentric feature and has a separation preventing threaded member embedded therein. The body of the club head has a sole in which a recessed cavity is formed to correspond to the joint portion. A fastening threaded member is fit with a washer and is inserted through the recessed cavity to threadingly engage the separation preventing threaded member for fixing the ferrule. As such, with the fastening threaded member loosened, the ferrule is rotatable to realize direction change in order to enhance ball hitting performance.
