Abstract
Disclosed is a golf tee foldable, through rotation, in a direction of a drive swing to prevent breakages and loss and increase the drive shot distance. The golf tee comprises a ball platform; a supporting pillar connecting the ball platform to a coupling ball; and a ball coupling portion having a fixation pin. The ball is coupled to the ball coupling portion via an elongate burrow circumferentially defined on the outer surface of the ball, which mates with an elongate ridge formed on a hemispherical inner surface of the ball coupling portion. At the stroke of a drive swing, the burrow slides over the relatively shorter ridge to allow rotation of the coupling ball and supporting pillar, causing the golf tee be fold in a direction of the drive swing.
