Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a tennis hitting auxiliary device. Background Technique

[0002] In the process of tennis teaching and training, how to hit the ball accurately plays a key role in the improvement of tennis skills. Especially for beginners, basic movements such as the position of the racket and the tennis ball and the hitting angle at the moment of hitting the ball need to be repeatedly learned and trained.

[0003] The authorized announcement number is CN212038908U, which discloses a tennis hitting auxiliary device. In this patented technology, the tennis ball is suspended by a second support frame. When a trainer conducts hitting training, since the tennis ball is suspended in the air by a pulling rope, the trainer has sufficient time to understand and think about details such as the position and angle between the racket and the tennis ball when hitting the ball. The trainer can use the racket to hit the tennis ball and conduct repeated practice and thinking. Since a spring is provided inside the second support frame and the spring is connected to the pulling rope, the hit tennis ball first moves outward, stretching the spring. Under the action of the spring, the tennis ball slowly decelerates and returns to its original position, preventing the tennis ball from being pulled back instantly after being hit, which may damage the tennis ball and accidentally injure the trainer. The utility model has a simple structure, can assist the trainer in hitting training, and does not require picking up the ball, saving time. However, in this scheme during tennis training, although a single tennis ball can be hit multiple times without replacement, this training method of hanging the tennis ball and hitting it repeatedly will not only cause the tennis ball to fall off after being hit for a long time, but also such repeated hitting cannot bring good training efficiency. Therefore, a tennis hitting auxiliary device is needed to improve the above problems. Content of the Utility Model
