Abstract

The invention discloses an automatic serving device for sports tennis. The device comprises a body, vertical plates are fixedly installed on the two sides of the body respectively, the top of each vertical plate is rotationally connected with a movable plate, a limiting mechanism is further arranged between each vertical plate and the corresponding movable plate, the limiting mechanisms can limitrotation of the movable plates, the movable plates are each of a U-shaped structure, sliding plates are arranged in the movable plates, the sliding plates are connected with the corresponding movableplates through first telescopic rods respectively, a plurality of second telescopic rods are fixedly installed on the opposite faces of the two sliding plates, and movable rods of the second telescopic rods are each of a hollow structure. The single-chip microcomputer control system randomly calls a tangent angle from the data storage module. The tangent angle can be adjusted by stretching the second telescopic rod for different lengths; after the tennis ball makes contact with the elastic plates, the track of the tennis ball is changed, the defect that in the prior art, the ball serving routeis single is greatly overcome, the two elastic plates can be alternately tangent to the tennis ball, the movement track of the tennis ball can be further enriched, and the tennis ball is more suitable for tennis players to use during single-person training.

Description

technical field [0001] The invention belongs to the field of tennis training, in particular to an automatic serving device for sports tennis.
