#The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

#Referring to FIGS. 4 to 7, a preferred embodiment of the present invention comprises a base (50) having a vertical popping device (60) on the base (50), and the popping device (60) further comprises a loading stand (61), a suspending stand (62), a pressure cylinder module (63), a compressed spring (64), an accommodating chamber (65), and a ball guiding track (66); wherein: said loading stand (61) is substantially in the shape of the letter “n”, having a penetrating hole (611) at the top, and a through hole (612) on the side, and the whole structure is coupled onto the base (50) by the coupling element (613); said suspending stand (62) is substantially in the shape of a letter “u”, having a penetrating hole (621) at the bottom, and being fixed onto the loading stand 61 by another coupling element (622); said pressure cylinder module (63) is fixed onto the suspending stand (62) by screw nut (631) and a contractible axle (632) extending upward into the suspending stand (62) and a compressed spring (64) being installed on the contractible axle (632); said accommodating chamber (65) is a pipe section, being soldered onto the top of the loading stand (61), having a through hole (651) on the side wall of the pipe, such that the position of the through hole (651) is inclined against the ball guiding track (66) and the ball can roll into the accommodating chamber (65) through the through hole (651), and as the contractible axle (632) of the pressure cylinder module (63) spontaneously pops out and in the mean time pushes the compressed spring (64) to shoot out the baseball for the batter's practice.

#Please refer to FIG. 9, which shows a plurality of popping devices (60) on the base (50A) so that they provide the different kinds of inner ball, central ball, and outer ball for the batter's practice.
