An upper toggle rod capable of toggling the steering assembly is fixedly installed on the side of the upper gear close to the serving box. The driving wheel drives the driven wheel to rotate synchronously under the meshing force, and the driven wheel drives the driven rod to rotate coaxially after synchronous rotation. When the driven rod rotates, it drives the lower gear to rotate coaxially. The lower gear drives the upper gear to rotate in the opposite direction under the meshing force.

The lateral sliding of the striking rod 903 drives the striking block 904 to move laterally. The lateral displacement of the striking block 904 compresses the striking spring 905. When the sector gear 502 is disengaged from the gear rod 901, the striking spring 905 extends and exerts force to push the striking block 904 to move laterally rapidly. The striking block 904 hits the basketball, thereby achieving a passing action.

[0033] In this embodiment, Figures 1 to 10 As shown, the top surface of the steering plate 703 is an inclined surface, and the steering plate 703 is arranged horizontally with the serving box 1 when it is in the initial state. Under the action of gravity, the basketball contacts the guide block 3 and rolls onto the steering plate 703 under the action of gravity. Under the guidance of the inclined surface of the steering plate 703, the outer wall of the basketball abuts against the outer wall of the hitting block 904.

[0034] The use method and advantages of the present invention: When the adaptive basketball training auxiliary device is working, the working process is as follows:

[0035] like Figures 1 to 10 As shown, a basketball is placed into the guide tube 2. Under the action of gravity, the basketball contacts the guide block 3 and rolls onto the deflection plate 703. Under the guidance of the inclined surface of the deflection plate 703, the outer wall of the basketball abuts against the outer wall of the striking block 904.

[0036] The drive motor 501 is started, and the drive motor 501 drives the sector gear 502 to rotate coaxially. Under the meshing force, the sector gear 502 drives the gear rod 901 to move laterally. The lateral movement of the gear rod 901 drives the striking rod 903 to slide in the serving box 1. The lateral sliding of the striking rod 903 drives the striking block 904 to move laterally. The lateral displacement of the striking block 904 compresses the striking spring 905. When the sector gear 502 is disengaged from the gear rod 901, the striking spring 905 extends and exerts force to push the striking block 904 to move laterally rapidly. The striking block 904 strikes the basketball, causing the basketball to be ejected horizontally from the serving box 1.

[0037] After the sector gear 502 is disengaged from the gear rod 901, it will mesh with the transmission gear 503 and drive the transmission gear 503 to rotate. When the transmission gear 503 rotates, it will drive the driving wheel 505 to rotate coaxially. The driving wheel 505 drives the driven wheel 601 to rotate synchronously under the meshing force. After the driven wheel 601 rotates synchronously, it drives the driven rod 602 to rotate coaxially. When the driven rod 602 rotates, it drives the lower gear 603 to rotate coaxially. The lower gear 603 drives the upper gear 605 to rotate in opposite directions under the meshing force. The lower gear 603 and the upper gear 605 can drive the upper toggle rod 607 and the lower toggle rod 604 to do circular motion. The upper toggle rod 607 and the lower toggle rod 604 periodically toggle the steering cam 701 to deflect. When the steering cam 701 deflects, it can The steering rod 702 is driven to move coaxially, and the steering rod 702 drives the steering plate 703 to deflect coaxially. After the steering plate 703 is deflected from the horizontal position to the inclined position, the bottom of the steering plate 703 will abut against the inner bottom wall of the serving cavity. At this time, the striking block 904 moves laterally and hits the basketball to launch a curved throw. At the same time, the steering rod 702 drives the positioning wheel 704 to rotate. The rotation of the positioning wheel 704 can push the plug-in block 801 to slide along the limit plate 804 into the fixed compartment 803. After the plug-in block 801 shrinks into the fixed compartment 803, it will compress the return spring 802. When the steering plate 703 moves to the horizontal position again, the plug-in block 801 will be inserted into the positioning wheel 704 under the telescopic force of the return spring 802, thereby completing the limitation of the positioning wheel 704.
