[0028] Embodiment 2, as Figure 2-Figure 4 As shown, the launching mechanism 2 includes a connecting block 201, a lower ball hole B202 is provided on the top of the connecting block 201, a shell 203 is fixedly sleeved on the outer wall of the connecting block 201, two driving motors 204 are fixedly connected to one side of the outer wall of the shell 203, transmission shafts B205 are fixedly installed on the output ends of the two driving motors 204, and the outer walls of the two transmission shafts B205 are movably connected to the inner wall of the shell 203, the outer walls of the two transmission shafts B205 are fixedly sleeved with launching roller shafts 206, a launching notch 207 is provided on one side of the outer wall of the shell 203, and the bottom of the ball bucket 109 is fixedly connected to the top of the connecting block 201.

[0029] The effect achieved by the entire embodiment 2 is that, under the joint action of the ball-blocking prevention mechanism 1 and the launching mechanism 2, a lower ball hole B202 is opened on the top of the connecting block 201, and a shell 203 is fixedly sleeved on the outer wall of the connecting block 201, wherein the interior of the shell 203 is designed with a tennis arc-shaped rolling track.

[0030] Working principle: When in use, first put tennis balls into the ball bucket 109, then start the two drive motors 204, and then start the stepper motor 103. A transmission shaft A104 is fixedly installed at the output end of the stepper motor 103, and a ball guide convex plate 105 is fixedly connected to the top of the transmission shaft A104, wherein a plurality of ball guide blocks 106 with limited holes 107 are fixedly connected to the outer wall of the ball guide convex plate 105, and the ball guide convex plate 105 is movably inserted into the interior of the ball bucket 109, and the transmission shaft A104 is fixedly installed at the output end of the stepper motor 103. The outer wall of the moving shaft A104 is movably sleeved with a ball bucket 109, which is fixed to the bottom plate 101 by three support columns 108, so as to ensure the stability of the ball bucket 109 and enable the stepper motor 103 to drive the ball guide convex plate 105 to rotate regularly. Under the action of the convex part of the middle part of the ball guide convex plate 105, the tennis ball rolls toward the peripheral limiting holes 107 under the action of gravity, and at the same time, the tennis ball in the ball bucket 109 is moved by the limiting holes 107 as the stepper motor 103 rotates.

The two launching rollers 206 are driven by the two driving motors 204 to rotate at high speed. Under the action of the high-speed rotating launching rollers 206, the tennis ball is sucked between the two launching rollers 206 by the two launching rollers 206 under the influence of the rotational force, and is launched out through the launching slot 207 under the action of the high-speed rotating force. At the same time, a ball blocking column 111 is fixedly connected to the inner surface wall of the ball bucket 109. Under the action of the ball blocking column 111, multiple tennis balls are prevented from falling into the lower ball hole A110 during the rotation gap of the stepper motor 103. In this way, the occurrence of ball blocking is avoided, the training efficiency of athletes is improved, the serving frequency of the serving device is controlled by the stepper motor 103, the flexibility and adaptability of the device are improved, and the practicality of the serving device is enhanced.
