After the bag is filled with balls, another key is pressed down, the motor 13 is started, one electromagnet is electrified reversely, the two electromagnets repel each other, the slide rail 9 and the rack 14 move backwards, the rack 14 is meshed with the gear 12 again, the rack 14 is driven to move upwards through the action of the motor 13, meanwhile, the vertical rod 5 and the frame body 1 are driven to move upwards, when the bag 17 on the frame body 1 passes through the bag taking device, the bag 17 is separated from the frame body 1 through the bag taking device, the frame body 1 is reset, and the frame body 1 is closed to be in a straight line through the extrusion action of the side frame body. At this time, the horizontal push rod 15 pushes the first spring piece 24 upwards, meanwhile, the stop rod 20 is driven to move upwards, the lower end of the stop rod 20 does not block the stop block 7 any more, so that the sliding table 8 moves under the thrust action of the first spring 3, the lower end of the second spring piece 26 is pushed by the stop block 7, the second spring piece 26 pulls the first spring piece 24 through the pull block 25, the lower end of the first spring piece 24 is separated from the push rod 15, the stop rod 20 is pushed downwards under the action of the third spring 22, the lower end of the stop rod 20 is pushed against the upper edge of the sliding table 8 again, the stop block 7 blocks the sliding table 8 from sliding continuously, the sliding table 8 slides by a distance of a stop block 7 in the process, the previous vertical rod 5 leaves from the rear of the rack 14, the next vertical rod 5 moves to the rear of the rack 14, then the electromagnet is electrified to attract, the vertical rod 5 is pushed downwards by the second spring 10, and therefore the ball throwing training can be continued. The sliding table 8 is moved for the purpose of changing the vertical bar 5 and the frame 1, i.e. the bag 17. After the bag 17 is filled with balls, the bag is placed at the place where the player takes the balls, and the zipper is unzipped so that the player can take the balls conveniently.
It is noted that while the present invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various modifications can be made therein without departing from the spirit and scope thereof.
