[0002] With the rapid development of social economy and the improvement of health awareness, tennis has become a popular swing sport. However, existing tennis training auxiliary tools and sports devices have the following shortcomings:

[0003] Existing serving devices are directly exposed to the athlete's field of vision. Athletes can easily predict the serving position and angle, but cannot simulate the unpredictable ball paths and tactics in real confrontation. For example, some tennis serving machines on the market, such as a serving machine based on machine vision (CN117379766A) and a serving machine for tennis training and its use method (CN117065306A), usually use a single-point launch method, so that the serving position, rhythm, angle and speed are relatively fixed and single, and athletes can see the position of the serving machine and easily predict the serving. The above-mentioned equipment can often only serve according to the preset program and angle, and cannot experience the changeable and unpredictable ball paths and tactics when confronting a real opponent, which limits the practitioner's reaction speed and adaptability. In addition, the existing tennis training facilities also have the disadvantages of being unable to be flexibly adjusted according to the size of the actual venue and inconvenient to disassemble and assemble.
