1. A fixed point contact practicing machine, comprising a vertically popping device disposed on a base of the practicing machine; a loading stand, a suspending stand, a pressure cylinder module, a compressed spring, an accommodating chamber, and a ball guiding track characterized in that: said loading stand having a penetrating hole in a top and a through hole in a side of the loading stand; said suspending stand having a penetrating hole at its bottom, being fixed into said loading stand by a coupling element; said pressure cylinder being fixed to the bottom of the suspending stand by a screw nut, and having a contractible axle passing through the penetrating hole of the suspending stand into an interior of the suspending stand, said compressed spring being installed on the contractible axle; the accommodating chamber is fixed vertically onto the top of the loading stand, and a through hole being disposed on a side wall of the accommodating chamber so that an external side of the through hole extends and inclines against the ball guiding track being fixed in position by a propping board; wherein by means of such arrangement, a baseball is placed into the ball guiding track and rolled into the accommodating chamber, and the contractible axle of the pressure cylinder pushes out and pushes the compressed spring to shoot out the baseball from the accommodating chamber to provide practice for baseball batters.
