Abstract

A tennis ball serving device solves the problems that an existing tennis ball serving device is single in function and low in application range, and different training modes cannot be adjusted according to the levels of different learners to improve the tennis technology of the learners. The tennis ball serving deviceincludes a lifting frame, an angle-adjustable launching cylinder, a driving shaft and a racket frame capable of rapidly swinging back and forth, an ejection rod is arranged in the launching cylinder, an ejection rack is fixedly connected to the ejection rod and meshed with an incomplete gear, the incomplete gear is coaxially and fixedly connected with a first regular polygon prism, and the first regular polygon prism is rotationally connected with a shell. The driving shaft is provided with a plurality of driving teeth which are circumferentially and uniformly distributed, the front ends of the driving teeth are flush, the lengths of the rear ends of the driving teeth are sequentially increased, and the first regular polygon prism is provided with an adjustable driven gear. The tennis ball serving device is diversified in function, different modes can be switched for training, the training difficulty and the training intensity can be adjusted according to the level of a learner, the application range is wide, and the tennis skill of the learner can be improved conveniently.

Description

technical field [0001] The invention belongs to the field of sports auxiliary equipment, in particular to a tennis ball serving device.
