Description

Technical Field

[0001] The utility model relates to the field of sports equipment, in particular to a tennis training transmitting and receiving integrated device. Background Art

[0002] At present, in order to facilitate the picking of balls in tennis halls, a type of hand-pushed tennis ball picking cart has appeared. This type of ball picking cart is semi-automatic and requires human operation. In addition, it is large and heavy. Manual operation not only wastes space, but also affects the training personnel's playing. If a special ball picker is assigned, it wastes human resources. This semi-automatic tennis ball picking tool is only suitable for situations where there are many ground balls. When there are few ground balls, there is no need to use the above-mentioned ball picking cart. The existing tennis ball serving machines used for serving in tennis halls have low technological content, high prices, and are easily damaged, which to a certain extent affects people's use. Therefore, it is necessary to develop a tennis ball collecting and serving function integrated device to solve the above problems. Utility Model Content
