The first gear 805 and the knob 803 are connected by setting the rotating rod 804. The first gear 805 and the knob 803 are respectively located on the inner and outer sides of the connecting block 801.
[0027] The first gear 805 is meshed with a tooth plate 806, which matches the first gear 805. The tooth plate 806 is fixedly connected to the sliding rod 802. The tooth plate 806 is fixedly connected to a limit plate 807. The limit plate 807 is provided with two pieces and is fixedly connected to the upper and lower ends of the tooth plate 806 respectively.
[0028] The first gear 805 is provided with a hole 808, and a limiting rod 809 is slidably connected to the hole 808. There are a plurality of holes 808, which are evenly distributed around the center of the first gear 805. The limiting rod 809 has the same number and distribution as the holes 808, and the limiting rod 809 is slidably connected to the connecting block 801.

Two driving wheels 905 are provided and are respectively arranged on the upper and lower sides of the exit of the serving channel 902, and the two driving wheels 905 are connected in series.
[0031] The working principle of this embodiment is as follows: when in use, a table tennis ball is put into the collecting bucket 4, and the table tennis ball enters the second channel 6 along the first channel 5. Since the second channel 6 has a certain inclination with the horizontal line, the table tennis ball is discharged from the outlet of the serving channel 902 along the second channel 6 under the action of gravity, and the first motor 904 is started, and the first motor 904 drives the driving wheel 905 to rotate on the supporting plate 903. Driven by the driving wheel 905, the table tennis ball is launched, thereby achieving the purpose of automatically launching the table tennis ball.
[0032] When the launch trajectory of the table tennis ball needs to be adjusted, the pull rod 811 is pulled, and the pull rod 811 drives the baffle 812 to slide on the inner wall of the fixed block 810, and the baffle 812 drives the limit rod 809 to disengage from the hole 808 on the first gear 805.

The connecting block 801 drives the end of the second channel 6 away from the serving channel 902 to rotate around the movable rod 7, so that the angle facing the serving channel 902 on the second channel 6 changes. After adjusting the appropriate angle, the pull rod 811 is released. Under the action of the spring 813, the pull rod 811 drives the limiting rod 809 on the baffle 812 to be inserted into the hole 808, and the first gear 805 is stuck in the connecting block 801. The second channel 6 is fixed, thereby achieving the purpose of adjusting the launching trajectory of the table tennis ball.
[0033] Embodiment 2
[0034] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 5 A second motor 10 is fixedly connected to the bottom of the collecting bucket 4, and a turntable 11 is fixedly connected to the output end of the second motor 10. The turntable 11 is rotatably connected to the inner wall of the collecting bucket 4. A limiting hole 12 is provided on the turntable 11. There are multiple limiting holes 12 and they are evenly distributed around the center of the turntable 11. The diameter of the limiting hole 12 is the same as the diameter of the ping-pong ball. When the turntable 11 rotates, the center position of the limiting hole 12 can be on the same vertical line as the center of the first channel 5 at a certain moment.
[0035] The working principle of this embodiment is as follows: the collecting bucket 4 is filled with ping-pong balls. When the ping-pong balls pass through the first channel 5, a large number of ping-pong balls will gather in the first channel 5 due to the excessive number of ping-pong balls, which may easily cause the ping-pong balls to be stuck between the first channel 5 and the second channel 6, and the ping-pong balls cannot be launched. This problem can be solved by setting the turntable 11 and the limiting hole 12. By setting the turntable 11 and the limiting hole 12, when the collecting bucket 4 is filled with ping-pong balls, the second motor 10 is started, and the second motor 10 drives the turntable 11 to rotate. Since the limiting hole 12 is provided on the turntable 11, the turntable 11 is provided with a plurality of limiting holes 12. 2, so the turntable 11 can prevent most of the table tennis balls from entering the first channel 5, and the table tennis balls entering the limiting holes 12 will be driven by the turntable 11 to move. Only when the turntable 11 rotates until the limiting holes 12 and the center of the first channel 5 are located on the same vertical line, the table tennis balls located in the limiting holes 12 will pass through the first channel 5 into the second channel 6, thereby avoiding the problem that a large number of table tennis balls will gather in the first channel 5, which may easily cause the table tennis balls to be stuck at the position between the first channel 5 and the second channel 6 and unable to be launched, thereby achieving the purpose of limiting the table tennis balls entering the first channel 5.
