发明名称 Batting practice device
摘要 A batting practice device for training a user to hit a ball. The batting practice device includes a stabilizing member, a connecting bar, a vertical post, a upper vertical member, a rotating arm and a ball. The stabilizing member is used for providing ballast for the batting practice device. The connecting bar couples the stabilizing member to the vertical post portion. In addition, the upper vertical member is rotatably coupled to the vertical post portion. The rotating arm has a first end and a second end. The first end of the rotating arm is coupled to the upper vertical member. The ball is coupled to the second end of the rotating arm. Thus a force asserted on the ball rotates the ball and rotating arm around the vertical post portion.
