Abstract

The invention discloses a ball serving machine, which comprises a base plate and a hollow shell. A support rod is arranged on one side of the upper surface of the base plate. The top of the support rod is connected to one side of the bottom of the hollow shell through a hinge. The other side of the upper surface of the base plate is provided with a bottom threaded rod, the rod body of the bottom threaded rod is connected to one end inside a threaded sleeve through a threaded structure, and the other end inside the threaded sleeve is connected to a second threaded rod through threads and the thread direction of the threaded structure in the first threaded rod is opposite to that of the threaded structure in the second threaded rod, and the top of the second threaded rod is connected to the other part of the bottom of the hollow shell through a hinge On one side, an air storage chamber is arranged in the center of the hollow casing. The present invention provides strong air pressure through the force between the magnetic poles to provide the power required for serving. At this time, the angle can be adjusted, the serving range is large, and the weight is light and easy to carry.
