Abstract
A tennis ball serving device comprises an air pump, a supply apparatus and an emitter; the emitter is composed of an emitting tube sleeve, an emitting tube and a ball rotating sleeve; the emitting tube sleeve includes a silica gel pipe with the inner diameter slightly smaller than the diameter of a tennis ball; a pipe hoop capable of adjusting the inner diameter of the pipe is disposed on the outer wall of the silica gel pipe. The combination of the emitting sleeve composed of a silica gel pipe with good contracting elasticity and the pipe hoop capable of adjusting the pipe diameter, not only is beneficial to increasing the instant emitting speed of a ball, but also can realize the ball emissions of different distances by adjusting the pipe diameter; in addition, a ball rotating piece disposed in the ball rotating pipe sleeve on the front is beneficial to rotating the ball, at the same time the ball flying channel can cause the flight track of the ball to vary by the influence of helical; thereby the training is more like an actual game.
