Compared with the prior art, the invention has the beneficial effects that: in an initial state, the limiting column is located in the limiting groove, and the swing switching gear is in transmission connection with the second transmission gear.

When the product is used, the product is moved to a wide area, the switch is switched on and turned on, the controller controls the driving motor to work, the motor gear rotates, the second transmission gear rotates to drive the first transmission gear to rotate, and the first transmission gear rotates to drive the swing gear to rotate. The swing gear rotates to drive the eccentric driving column which is eccentrically arranged to rotate, the eccentric driving column rotates to drive the swing arm sliding groove to move, the swing arm swings around the adjusting support column in a reciprocating mode, and the swing arm swings to drive the outer edge hole to move so that the rotating disc rotates in a reciprocating mode. The rotating disc rotates to drive the rotating upright post to move synchronously, the rotating upright post moves to drive the ball barrel to move, and then the orientation of the ball outlet hole of the ball barrel is changed in a reciprocating periodic manner on the horizontal plane, namely the flying position of the ball is changed in a reciprocating periodic manner on the horizontal plane. When the horizontal sending range of the ball needs to be adjusted, a user can rotate the swing angle adjusting hand wheel to further rotate the swing angle screw rod, the swing angle screw rod rotates to enable the adjusting support to slide along the swing angle screw rod under the screw thread guiding effect, and the distance between the adjusting support and the swing gear is changed. When the regulation pillar is progressively close to the swing gear, the turned angle of swing arm increases to make the scope of serve of a ball section of thick bamboo increase, when the regulation pillar is progressively kept away from the swing gear, the turned angle of swing arm reduces, thereby makes the scope of serve of a ball section of thick bamboo reduce, thereby can satisfy different demands of different users to different positions of serving.

Meanwhile, the swing gear rotates to synchronously drive the central gear to rotate, the central gear rotates to drive the elevation angle rotating gear to rotate so as to synchronously rotate the positioning column, and the positioning column rotates to drive the positioning hole to rotate so as to synchronously and circumferentially rotate the driving column. The driving column rotates to drive the annular lifting groove to rotate, the annular lifting groove is an annular groove which is arranged along the circumferential direction and has reciprocating height change, and the annular lifting groove rotates to drive the driving rod to slide linearly and longitudinally in a reciprocating mode. The driving rod slides to drive the driving sliding groove to move so as to enable the driving arm to slide longitudinally in a reciprocating mode, the driving arm slides to drive the eccentric driven column which is eccentrically arranged to swing in a reciprocating mode, and therefore the ball barrel can swing in a reciprocating mode in the longitudinal plane, orientation of a ball outlet of the ball barrel can change periodically in the reciprocating mode in the longitudinal plane, and the position of flying out of a ball changes periodically in the reciprocating mode in the longitudinal plane. When the longitudinal service range of the ball needs to be adjusted, a user holds and rotates the pitching adjusting hand wheel by hands, so that the pitching screw rod rotates circumferentially, the pitching screw rod rotates circumferentially to enable the pitching nut to slide longitudinally under the thread guiding effect, the pitching nut slides longitudinally to drive the driving column to slide longitudinally, and the annular lifting groove moves longitudinally. When annular lift groove risees, vertical service scope risees, when annular lift groove reduces, vertical service scope reduces to can satisfy different users to the different demands of different service positions.

The inner synchronizing wheel rotates to drive the second synchronizing wheel to rotate through the ball feeding synchronous belt so as to enable the transmission bevel gear to rotate, the transmission bevel gear rotates to drive the ball feeding bevel gear to rotate so as to enable the ball feeding roller to rotate, the ball feeding roller rotates to drive the ball feeding belt to rotate, the two symmetrical ball feeding belts can be abutted to balls in the ball barrel, and then the balls move towards the direction of the ball outlet under the driving of the ball feeding belts. Meanwhile, the inner synchronizing wheel rotates to drive the first synchronizing wheel to rotate through the ball-launching synchronous belt, the first synchronizing wheel rotates to drive the parrot spiral gear fixedly connected with the first synchronizing wheel to rotate, the parrot spiral gear rotates to drive the parrot spiral gear in transmission connection with the parrot spiral gear to rotate so that the adjacent variable-speed bevel gears rotate, and the rotating speed of the variable-speed bevel gears changes in a reciprocating periodic mode. The rotation of the speed change bevel gear drives the ball serving bevel gear to rotate so as to enable the ball serving wheel to rotate, and the ball serving wheel rotates to drive the ball which is abutted against the ball serving bevel gear to rapidly fly out through the ball outlet hole after the ball which is driven by the feeding belt is abutted against the ball serving wheel. The rotating speed of the variable-speed bevel gear is changed in a reciprocating periodic manner, so that the rotating speed of the service wheel is changed in a reciprocating periodic manner, the initial speed of the ball flying out through the ball outlet hole is different, and the flying trajectory of the ball flying out is different due to the fact that the ball flies in a parabolic trajectory.

When the ball throwing device is used by a user, when a ball is thrown, the ball passes through the ball frame or passes by the ball frame and falls into the ball receiving net, the ball rolls into the ball inlet under the action of gravity and then enters the ball barrel, then the ball moves to be abutted against the ball serving wheel under the driving of the ball conveying belt, and immediately, the ball is quickly sent out through the ball outlet under the driving of the ball serving wheel. Because the time of throwing the ball is random, and the ball is received the ball net resistance diverse after falling into the ball net simultaneously to make the time that the ball enters into the ball section of thick bamboo random. In the process, the orientation of the ball outlet hole in the horizontal range and the longitudinal range is periodically changed in a reciprocating manner, and meanwhile, the rotating speed of the ball serving wheel is periodically changed, so that the ball sending position and the track are randomly changed after the ball is thrown. The ball catching range of the user is enlarged, so that the user needs to run when catching the ball, the ball catching device is closer to the actual motion situation, the motion scene is enriched, the training intensity is increased, and the motion pleasure is also increased.

The switching sliding head slides to drive the annular groove to slide so as to enable the switching shaft to slide along the axial direction, the switching shaft slides to drive the swinging switching gear to move, and then the swinging gear can move to be not in contact with the second transmission gear. Meanwhile, the switching shaft slides to synchronously drive the reversing bevel gear to move, so that the reversing bevel gear moves to be in transmission connection with the lifting bevel gear. At the moment, the limiting column moves to be opposite to the other adjacent locating groove, the unlocking block is loosened, the limiting column moves downwards under the action of the elastic force of the tension spring, and the limiting column enters into the limiting groove opposite to the limiting column, so that the switching deflector rod and the base are relatively fixed.
