The new model relates to a ball return device, in particular to a ball return device for training.

Ball games require not only sufficient endurance and explosive power, but also good skills. Therefore, in order to improve their skills, professional players need to practice repeatedly in addition to coaching.

Taking badminton as an example, there are currently two training methods for players:

1. Cooperate with coaches or other players to spar with each other: Since two players are playing against each other, there will be different ball paths under different thinking and different situations. Therefore, the ball paths change the most. However, the training time will be limited by the time of sparring players or coaches, and the mobility is low.

2. Serve the ball from the ball machine: It can cooperate with the training players to train at any time, and the ball path can be changed in various ways according to the set mode. However, the ball machine cannot return the shuttlecock. Therefore, each shot shot can only be hit back by the player once, which will consume a lot of shuttlecocks during the training process. In the same setting mode, the shot path is fixed and cannot be Train players to react on the spot when they catch the ball.

Therefore, the purpose of the present invention is to provide a ball return device for training that is not limited in use time, does not require the opponent's self-simulation training, and can improve the player's on-the-spot reaction.

Therefore, the new ball return device for training includes a support unit, a ball return unit, and a limit unit.

The support unit includes at least one bracket.

The ball returning unit is disposed on the at least one bracket and forms a scalable first included angle with a first axis, and includes a plate with elastic plasticity and suitable for rebounding a ball.
