发明名称 Baseball Bat
摘要 A baseball bat includes a hollow grip member having opposite front and rear ends, and an inner peripheral surface that defines a tapered chamber having a diameter reducing gradually toward the rear end. The inner peripheral surface has a first positioning portion disposed between the front end and the rear end. A striking member has an engaging segment received in the tapered chamber, and a large diameter segment extending forwardly from the engaging segment. The engaging segment has an axial hole, a plurality of open-ended slits extending along an axial direction and in spatial communication with the axial hole, and a second positioning portion aligned with the first positioning portion. A pressing member is inserted into the axial hole to press the second positioning portion against the first positioning portion.
