Problems solved by technology
[0003]
In the existing technology, these two products can be used to shoot tennis balls at a certain speed, but the former only relies on the motor to give the speed, which is very expensive and difficult to promote.
The latter, because it is ejected by compressed air, its noise is very loud, and it cannot achieve continuous launch, and the supplementary compressed air is limited, so the number of tennis balls launched at the same time by air launch is also limited
Tennis training is greatly hindered, and tennis fans' love for tennis is also greatly reduced

Description
technical field [0001] The invention is a tennis ball machine, which belongs to the technical field of sports equipment. Background technique [0002] Tennis takes place in the professional training that has begun to be widely used in athletes. All tennis ball launchers on the market have flaws. Its products are mainly divided into two categories: one is a double-motor launch tennis machine, which uses friction to provide power to the tennis ball; the other is to launch tennis balls in the form of compressed air. [0003] In the existing technology, these two kinds of products can realize the shooting of tennis balls at a certain speed, but the former only depends on the speed given by the motor, and its cost is high, the price is very expensive, and it is difficult to popularize. The latter, because it is ejected by compressed air, its noise is very loud, and continuous launch cannot be realized, and the supplementary compressed air is limited, therefore, the number of te...
