[0032] Working principle:

[0033] When in use, first fill all the ball placing tubes 8 with tennis balls, and align one of the ball placing tubes 8 with the ball outlet 10. During the ball supply process, start the pushing cylinder 17, and the piston end of the pushing cylinder 17 moves with the fixed plate 18, and the fixed plate 18 moves with the pulling plate 20 through the movable shaft 19, and the pulling plate 20 moves to a position close to the movable pulling block 13 and exceeds the movable pulling block 13, and then start the second motor 21, and the output shaft of the second motor 21 rotates with the first gear 22, so that the second gear 23 rotates with the movable shaft 19, and the movable shaft 19 rotates with the pulling plate 20, and then start the pushing cylinder 17 again, and the piston end of the pushing cylinder 17 retracts, so that the pulling plate 20 pulls the movable pulling block 13 to move, and the movable The pulling block 13 moves the connecting block 14 through the movable pulling rod 12, and the connecting block 14 moves the impact head 15. When the impact head 15 moves toward the direction close to the fixed block 11, the connecting spring 16 is compressed, and the tennis ball in the goal channel 4 enters the serving channel 3. At the same time, a tennis ball in the corresponding ball tube 8 enters the goal channel 4 for filling. Finally, the second motor 21 is started again to rotate the pulling plate 20, so that the pulling plate 20 is separated from the movable pulling block 13. At the moment when the movable pulling block 13 is separated, due to the action of the connecting spring 16, the impact head 15 is instantly reset, and the impact head 15 hits the tennis ball, so that the tennis ball flies out from the top of the serving channel 3 for ball supply, so that people can practice serving.

[0034] When the tennis balls in one ball placing barrel 8 are used up, the first motor 9 is started, and the output shaft of the first motor 9 rotates the rotating shaft 6, the rotating shaft 6 rotates the rotating disk 7, and the rotating disk 7 rotates another ball placing barrel 8 to the position corresponding to the ball outlet 10, and continues to fill the goal channel 4 with tennis balls. This greatly increases the number of balls supplied. At the same time, during training, other people can fill the empty ball placing barrel 8 with tennis balls, thereby greatly shortening the waiting time of the trainees, which is beneficial for people to improve the efficiency of serving training.
