Abstract

The invention relates to ball serving machine, in particular to a tennis ball serving machine. The tennis ball serving machine achieves the technical purposes that the height and direction of ball serving can be adjusted, the training effect is good, and pair exercise for training can be achieved without the cooperation of another person. According to the technical scheme, the tennis ball servingmachine comprises a base, annular sliding blocks, first sleeves, sliding rods, first springs, a serving tube, a rack, a second spring, a discharging tube, a discharging hopper, a handle, a pushing block and the like; annular sliding grooves are formed in the middle of the top of the base, the annular sliding blocks are slidably arranged in the annular sliding grooves and are in sliding fit with the interiors of the annular sliding grooves, and the two first sleeves achieve a guiding effect. According to the ball serving machine, a proper quantity of tennis balls are put into the discharging hopper, one of the tennis balls falls into the serving tube to be in contact with the pushing block, then under the effect of a linear motor, the position of the serving tube can be adjusted, and then the tennis ball serving direction is adjusted.

Description

technical field [0001] The invention relates to a ball serving machine, in particular to a tennis ball serving machine.
