At the same time, the sleeve rod 1003 slides into the sleeve 1002, and the second spring 1004 is compressed, thereby opening the dust suction hole 20.

[0040] Working principle: When in use, first, start the motor 906. The rotation of the motor 906 drives the rotation of the threaded rod 904, which can drive the third slider 905 and the second slider 903 to move, thereby driving the second rack 802 to move, and driving the third rack 804 to move synchronously through the connecting frame 803, thereby driving the two second gears 801 and the first rotating shaft 11 to rotate, and then driving the support plate 13 to rotate through the L-shaped plate 12, so that the two support plates 13 can be rotated closer to or farther from each other to match the width of the court;

When the volleyball hits the rotating plate 22, the rotating plate 22 can be pushed to rotate upward along the second rotating shaft 501. At the same time, when the second rotating shaft 501 rotates, the first gear 601 is driven to rotate synchronously, and then the first rack 602 is driven to slide along the first guide rod 702. The first spring 704 is compressed. When the volleyball passes over the rotating plate 22, the rotating plate 22 can be rotated downward and reset under the action of the first spring 704, so that the volleyball can be limited.

[0042] Furthermore, when air enters the fixed box 401 through the exhaust pipe 305, it will impact the surface of the baffle 403, so that the third rotating shaft 402 rotates. The rotation of the third rotating shaft 402 drives the rotation of the rotating rod 201 and the conveying roller 202, and then drives the conveyor belt 14 and the triangular plate 16 to convey. Under the push of the triangular plate 16, the volleyball can be driven to be conveyed, and enter the ball delivery pipe 102 through the goal hole 24, and be transported to the serving module 103 for launching under the action of the conveying module 104, so as to facilitate the collection and re-launching of the volleyball, without manual input, and is more convenient and quick to use. In addition, when the volleyball is conveyed, the surface of the volleyball can be cleaned by the bristles 18, and at the same time, the impurities on the surface of the volleyball can be absorbed by the adsorption holes 15, and filtered and collected through the filter box 303, so that the serving effect is better.

[0043] After use, the electromagnet 1005 can be energized. After being energized, the electromagnet 1005 attracts the iron block 1006, so that the sealing plate 23 moves toward the direction close to the support block 1001. At the same time, the sleeve rod 1003 slides into the sleeve 1002, and the second spring 1004 is compressed, thereby opening the dust suction hole 20. At this time, the vacuum operation can be performed through the dust suction hole 20, and the mobile base 101 is pushed to move, so that the impurities on the surface of the court can be absorbed through the dust suction hole 20 and can enter the filter box 303 for collection, which is more functional and more convenient to use.
