Abstract

The invention relates to a tennis ball launching device, in particular to an automatic tennis ball launching device. The technical problem is to provide the automatic tennis ball launching device, which can well control ball launching strength and angle, and the training quality is not affected. The automatic tennis ball launching device comprises a bottom plate, a feeding barrel, a launching barrel and the like. The feeding barrel is fixedly connected to the upper side of the bottom plate, and a launching barrel is fixedly connected to the end of the feeding barrel. Tennis balls in the launching barrel can be pushed through a first push block to make the ball launched out, people can pull a pull rod to the same position every time to guarantee the ball serving strength, the launching barrel is fixed, and the ball serving angle can be guaranteed, so that the training quality is not affected; and under the action of a silencing pad and a buffer spring, when the tennis ball is launched from the opening in the rear end in a launch canister, the effects of silencing and shock absorption can be achieved.

Description

technical field [0001] The invention relates to a tennis ball launching device, in particular to an automatic tennis ball launching device.
