Abstract

The height-adjustable tennis training device comprises a bottom plate, first supporting blocks are connected to the two sides of the top of the bottom plate, and two universal wheels are connected to the bottoms of the first supporting blocks; the sleeve is connected to one side of the first supporting block, the screw rods are rotationally connected between the sleeve and the first supporting block, the ball net is connected between the screw rods in a threaded connection mode, and the ball net is slidably connected with the sleeve; the transmission mechanism is arranged between the bottom plate and the screw rod; and the spraying mechanism is arranged on the first supporting block on one side. The spiral rod can be driven to rotate through the transmission mechanism, the spiral rod rotates to adjust the height of the ball net, and a tennis ball can be ejected through the ejection mechanism, so that a trainer does not need to throw the ball to the trainer, and the effects of adjusting the height of the ball net, serving the ball and reducing the training intensity of the trainer are achieved.

Description

technical field [0001] The invention relates to a tennis training device, in particular to a height-adjustable tennis training device. Background technique [0002] When performing tennis training, the trainer stands on one side of the net, and then the trainer throws the ball to the trainer vigorously, and the trainer catches the ball. Can not carry out height adjustment, thus can not be well applicable to trainers of all ages, also generally can not serve, thereby needs trainer to serve, and the training intensity of trainer like this is bigger, more tiring. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art and provide a height-adjustable tennis training device capable of adjusting the height of the net, serving and reducing the training intensity of the trainer. [0004] The present invention is realized in the following way: a height-adjustable tennis training device includes a bottom plate, a first supp...
