Abstract

The invention relates to the field of sports equipment, in particular to a tennis ball serving device for training. The device comprises a ball serving pipe, the top of the ball serving pipe is communicated with a ball storage box, a ball serving block slides in the ball serving pipe, a serving pressure spring is connected between the ball serving block and the closed end of the ball serving pipe, and a strip-shaped hole is formed in the side wall of the ball serving pipe. A clamping block is fixed to the side wall of the ball serving block, a moving block transversely slides on the outer side wall of the ball serving pipe, clamping teeth used for abutting against the clamping block are transversely slidably connected to the moving block, one end of each clamping tooth is provided with an inclined face, the inclined faces face a ball outlet of the ball serving pipe, a compression spring is connected between the other end of each clamping tooth and the moving block, and a magnet block is fixedly connected to each clamping tooth. An electromagnet used for attracting the magnet block is fixedly connected to the moving block, a first conductive block electrically connected with the electromagnet is fixedly connected to the moving block, and a second conductive block far away from the ball outlet is fixedly connected to the outer side of the ball serving pipe. According to the scheme, the technical problem that one person cannot complete tennis training is solved.

Description

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