Abstract
A ball holder and base plate fixing structure for batting practice apparatus is provided, including a sheath tube and a base plate. The sheath tube includes a first segment and a second segment, connected to each other. The first segment has a round tube shape for providing placing said ball holder. The second segment has a trumpet shape, said sheath tube having compressible resilience. The base plate has an installation hole. When assembled, the second segment of the sheath tube is compressed into the installation hole for tight engagement so as to fix the sheath tube to the base plate. In this manner, the ball holder is sheathed into the sheath tube and fixed to base plate. During batting practice, the resilience of sheath tube allows the ball holder to swing and twist on impact to absorb and annihilate some of the impact. After batting, the resilience of sheath tube can restore the ball holder to original position.
