Background technique

Basketball is a common sport. There are basketball courses in many primary schools. When primary school students learn basketball, they need to conduct shooting training in the early stage. Because primary school students are not good at shooting, the basketball may hit primary and middle school students after rebounding from the backboard. , causing primary school students injury, and frequently picking up the ball is also unfavorable for primary school students to carry out shooting training. Therefore, when carrying out basketball training, it is necessary to protect and collect by means of basketball training auxiliary devices, thereby assisting primary school students in training.

Existing basketball training aids generally include a collection frame, a C-shaped frame and a net bag. By setting the C-shaped frame under the backboard, the net bag is set on the C-shaped frame, and the net bag covers the bottom of the backboard. When the trainer shoots and hits the backboard, the basketball falls into the net pocket after rebounding from the backboard, and then the basketball falling into the net pocket flows along the net pocket to the collection frame, thereby completing protection and basketball collection. However, in the existing basketball training auxiliary device, when the trainer is training, the C-shaped frame and the net pocket will affect the trainer's shooting, and when the trainer's shooting strength is too large, the basketball will rebound beyond the range of the C-shaped frame and the net pocket. , the protection and collection effect is not ideal.
