[0002] In the field of sports equipment technology, ball serving equipment, as an important tool for auxiliary training, has a development history that is closely linked to scientific and technological progress and the improvement of sports training needs. In the early days, ball serving mainly relied on manual throwing, which was not only inefficient, but also difficult to achieve precise control of serving speed, angle and frequency, thus limiting the training effect and the improvement of athletes' skills. With the rapid development of electronic technology and automation technology, automated ball serving equipment came into being and gradually became an indispensable part of modern sports training.

[0003] Currently, most ball serving devices on the market adopt principles such as motor drive, pneumatic launch or mechanical ejection, which realize the automation of the serving process and a certain degree of adjustability. These devices control the speed, angle and frequency of the serve through preset programs, and can simulate different types of ball paths and hitting scenes, providing athletes with a comprehensive and efficient training experience. However, although the existing technology has made significant progress, in terms of the adaptability and flexibility of serving equipment, the existing equipment can often only be used for training balls of specific sizes or fixed serving angles, which is difficult to meet the use of balls of different sizes, resulting in poor use of the device, so staff are required to improve it.
