ABSTRACT:
This invention relates to a batting exercising device for baseball, it includes a longitudinal axis, an adjustable tripod used to support the longitudinal axis, a V rack which can horizontally rotate around the longitudinal axis, and a ball-like component installed on the end of the V rack, in which a switch providing an elastic resistance to the V rack is installed between the engaging pans of the V rack, and the single-way controllers which provide frictional resistance to one rotating direction of the V rack are installed on the top and bottom of the engaging pans respectively. By constructing the above components, the elastic and frictional resistance of the switch and the one-way controller can decrease the rotation speed of the V rack for safety consideration when the V rack is driven to rotate clockwise or counterclockwise by the ball-like component struck by the player.
