Tennis training device with rotatable tennis ball

Abstract

The invention belongs to the technical field of tennis training devices, and particularly relates to a tennis training device with a rotatable tennis ball, the tennis training device comprises an arc-shaped plate, a bearing block, a large round pipe and a collecting hopper, the bearing block is fixedly mounted at the top of the arc-shaped plate, the large round pipe is fixedly mounted at the top of the bearing block, a round hole is formed in the right side of the large round pipe, and the collecting hopper is arranged in the round hole. A spring is fixedly installed on the inner bottom face of the large round pipe, a through hole is formed in the left side of the large round pipe, the collecting hopper is rotationally connected with the top of the large round pipe through threads, a fixing plate is fixedly installed on the left side of the large round pipe, and a telescopic plate is connected to the top of the fixing plate in an embedded mode; according to the tennis training device with the rotatable tennis ball, the problem that when a trainer conducts training, one ball and one buckle are needed for one-time training can be fully solved, training can be well enhanced, and the time for the trainer to load the balls back and forth is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of tennis trainers, in particular to a tennis trainer with rotatable tennis balls. Background technique [0002] Many schools will offer tennis teaching classes. Tennis training requires players to perform position rotation. They must go to the front row to smash and block, but also to the back row to defend and respond. Players are required to fully master various skills. In horizontal competitions, the focus of confrontation is on the block on the net. Therefore, tennis trainer technology is the focus and difficulty of teaching. [0003] However, the existing tennis training device cannot realize that the trainer can perform spiking training on tennis balls in various directions and heights in front of the net during use, and the training effect of tennis spiking is relatively poor and the tennis balls cannot be dropped sequentially. Tennis spike training is more troublesome, and the training efficiency o...
