In the later stage of training, the LED light strip 8 can be covered to increase the difficulty of training, thereby being suitable for different training stages and improving the applicability of the device.

[0067] Working principle:

[0068] When using the device, the installed ball net 13 is moved to the bottom of the backboard. After the basketball enters the ball net 13, it passes through the limiting ring 11, the connecting port 20 and the guide claw 21, and finally enters the serving machine 5 through the goal hole 18. When it is necessary to adjust the height of the serve, the height of the fixed platform 4 is adjusted by starting the lift 3, and then the height of the serving machine 5 is adjusted. When it is necessary to serve in different directions, the external power supply is connected to start the servo motor 14 to drive the driving gear 15 to rotate and drive the driven gear 17 to rotate. The driven gear 17 rotates and drives the connecting shaft 16 to rotate. The connecting shaft 16 rotates and drives the serving machine 5 to rotate, thereby adjusting the serving direction of the serving machine 5.

[0069] When conducting a pass error training, the motor 9 is started by connecting an external power source to drive the wheel disc 22 to rotate inside the equipment box 7. The rotation of the wheel disc 22 drives the eccentric shaft 23 to rotate. When the eccentric shaft 23 rotates, it slides inside the curved groove 26 and pushes the crank 25 to swing. When the crank 25 swings, it drives the two connecting blocks 37 to move through the two connecting handles 36. The movement of the two connecting blocks 37 drives the slider 38 to slide inside the slide groove 32. The movement of the slider 38 drives the clamping block 39 to slide in the clamping groove 40. The movement of the slider 38 drives the first wedge block 43 to move.

[0070] The first wedge block 43 moves to contact with the second wedge block 44, and uses the contact of the inclined surface to push the second wedge block 44 to move toward the through slot 30, thereby driving the swing rod 33 to swing, and the swing rod 33 swings to push the guide block 42 out of the through slot 30;

[0071] At this time, when the basketball is ejected from the serving machine 5, the basketball is affected by the guide block 42 when passing through the serving tube 6, thereby changing the path of the ball.

[0072] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
