Abstract
An improvement of a swing ball device with adjustable heights for hitting practice, featured with varied swing frequencies and paths to enrich training, includes an elastic swing piece associated with a ball disposed in a supporting cup. By the elastic swing motion of the swing, the ball is able to swing left and right in a three-dimensional plane. The swing piece is disposed with one or more interval holes for connecting with pipes of different heights, depending on weights of the ball and a user's preference. The two lateral securing ears helps to secure the ball inside the supporting cup from falling off. The swing piece when coordinated with a through-pin or a compressed plate produces motions of different angles and frequencies in swing, facilitating training in the coordination of hands, eyes, and the brain.
