Abstract:
1. A practice golf club capable of adjusting head speed having a head (H) attached to an end of a shaft(S) having a grip (G), from which an impact sound is generated through a swing operation, wherein the head (H) comprises: a first body ( 100 ) coupled to the end of the shaft (S); a second body ( 110 ) having a tubular shape, both ends of which are open and adapted to be screw-coupled to the rear end of the first body ( 100 ); a moving weight ( 140 ) movably disposed inside the second body ( 110 ); a magnet ( 180 ) adapted to fix the moving weight ( 140 ) to the front end portion of the second body ( 110 ) by means of a magnetic force thereof; adjustment means adapted to adjust the gap between the magnet ( 180 ) and the moving weight ( 140 ) so as to control the strength of the magnetic force of the magnet ( 180 ) pulling the moving weight ( 140 ); a cap ( 120 ) screw-coupled to a rear end of the second body ( 110 ); and return means interposed between the cap ( 120 ) and the moving weight ( 140 ) to return the moving weight ( 140 ) to the original position when the moving weight ( 140 ) momentarily moves by centrifugal force and collides against the cap ( 120 ) to generate an impact sound.
