Abstract
A "baseball hitting exerciser" serving as both a hitting exerciser and a home base plate, including a flexible post, a connecting tube, a fixing tube, an anti-dust cover and a bottom cover. On the bottom end of the fixing tube is a neck connected to a push block; the push block serves to push the anti-dust plate that is compressed by the springs inside the fixing hole, so the push block may be turned and accommodated inside the wing plate troughs in the fixing hole; then, the fixing tube is fixed inside the fixing hole. If the connecting tube is turned again, the bias force of the springs pushing on the anti-dust cover will push the push block away from the fixing hole; so the base plate is restored to the shape of a normal base plate; so the base runner can safely use the base.
