发明名称 Ball hitting practice device
摘要 A ball hitting practice device has a base member, a post projecting upwardly from the base member and a pivot joint between the lower end of the post and the base member for allowing pivoting of the post in any direction about the base member to any selected tilt angle. A locking device is provided for securing the post at a selected angle and direction relative to the base member, and a cup is pivotally secured to the upper end of the post for supporting a ball. The cup can be pivoted relative to the post so as to face upwardly regardless of the tilt angle of the post relative to the base member.
