Abstract: A pitching device includes a case in which a shaft, a press board, a strike board, an activation unit and a slide are received. The press board and the strike board are located on two ends of the shaft, and a driving spring is mounted to the shaft so as to rotate the shaft. The strike board has a support member for receiving a ball and the activation unit controls the operation of the strike board. The balls are put in the slide. A release member is located between the slide and the support member to control entry of the ball into the support member. By continuously pressing the press board, the torsion force of the driving spring is stored. When the pedal unit is operated to release the activation unit, the strike board rotates by the torsion spring to through the ball in the support member.

Abstract: An artificial pitcher for practicing the hitting skill of baseball includes an artificial pitcher on a support and having a ball holder on top, a main spring biased a stroke which are held by a hook on a hollow interior cylindrical main body, and a control device positioned remote from the pitcher having a rope to control the hook to release the stroke to hit a baseball from the ball holder flying to a batter. In order to pitch a transforming ball, an angular adjustment plate is positioned beside the main body to help the main body to adjust its angle of elevation.
