[0002] In the field of sports training, ball machines are a common auxiliary device used to help athletes practice hitting and receiving the ball. Traditional ball machines can usually only launch a single type of ball and have limited adjustment capabilities, resulting in insufficient training flexibility.
[0003] The following are the limitations of existing technology:
[0004] 1. Single ball type compatibility: Traditional ball machines are usually designed for specific ball types, such as tennis or baseball machines, and cannot be compatible with balls of different sizes or weights. This requires users to purchase multiple machines, which is costly and takes up space.
[0005] 2. Inflexible angle adjustment: Most ball machines only support fixed elevation angle or horizontal rotation. Adjustment requires tools to remove screws, which is cumbersome. It is difficult to simulate the varied ball trajectories in real matches, such as high-arc balls and sidespin balls.
[0006] 3. Insufficient ball supply stability: The gap between the ball tube and the ball wheel is fixed, which makes the ball prone to getting stuck or unevenly rubbed, resulting in deviations in ball speed / direction, reduced training efficiency, and may even damage the machine or the ball.

Loosening the five-star nuts 16 at this location can adjust the angle between the first connecting block 13 and the support frame. The meshing teeth 18 design is beneficial to the stability after locking.
[0039] The conversion plate 5 of this invention can be replaced with a suitable conversion plate when launching different balls, so that the launching tube can be adapted to balls of different diameters, such as baseballs and tennis balls, thus solving the problem that traditional ball machines are limited to only one type of ball.
[0040] The ball-serving tube 1 of this utility model is integrally formed from symmetrical side tube walls and ball wheel shell, which has a stable structure and is easy to maintain.
[0041] The ball guide bar array 11 of this utility model: ball guide bars are set around the service wheel to guide the ball accurately into the friction zone of the service wheel and improve the consistency of the ball trajectory.
[0042] This utility model features a novel quick-assembly and disassembly support frame.
