Problems solved by technology

[0003] Because tennis is a sport that can only be carried out by at least two people, it cannot be performed when one is alone, so people have invented a tennis sparring device, but the current tennis sparring device has a single function, and is generally a beginner's sparring device that does not pass the net, and cannot be used to improve golf skills. However, most of the sparring devices for crossing the net are fixed-point launch and fixed-point drop balls, and it is prone to multi-ball bursts, and the training effect is poor.

Embodiment 1

[0024] like figure 1 , 2 The racketless tennis sparring device shown includes a box body 1, a fixed block 11 is fixedly installed inside the box body 1, and a ball opening 12 is opened at the upper end of the fixed block 11, and a certain space is reserved at the upper end of the fixed block 11 for storing The training ball can be practiced continuously for many times, and then the training can be continued after supplementation, and the training efficiency is high; the lower end of the goal opening 12 is equipped with a ball distribution roller 13 connected to it, and the lower end of the ball distribution roller 13 is provided with a discharge roller connected to it. The ball mouth 16, the lower end of the ball outlet 16 is provided with a service groove 4 connected to it, and the training balls on the top are divided into the ball outlet 16 one by one by the ball distribution roller 13, and then enter the ball outlet 4 to be launched for training; The groove 4 is set throu...

Embodiment 2

[0032] like image 3 As shown, this implementation is further optimized on the basis of Embodiment 1. A gravity sensor 23 is fixedly installed in the center of the tennis ball 15, a button battery 24 and a communication module 25 are installed on the outside of the gravity sensor 23, and a button battery 24 and a communication module 25 are installed on the outside of the communication module 25. There is a pressure sensing layer 26, the pressure sensing layer 26 includes a number of pressure detection devices, through the gravity sensor 23 and the pressure sensing layer 26 to detect the hitting position, and the detection result is sent to the controller 5 through the communication module 25 , through the controller 5, it is judged whether it is effective to hit the ball. When the second hitting position is a non-bottom hit, it is judged as an effective hit, and the number of effective hits and the total number of servings are counted on the display screen 7, which is convenie...
