Service device for tennis ball hitting training

Abstract

The invention discloses a service device for tennis ball hitting training. The service device comprises a bearing plate, wherein a vertical fixed plate is vertically fixedly arranged on the bearing plate; a storage groove is vertically fixedly arranged in a horizontal plate; a vertical conveying pipe, which penetrates the horizontal plate, is arranged at the lower end of the storage groove in a vertical communicating mode; a horizontal conveying pipe is horizontally fixedly arranged on the bearing plate via a supporting pillar; an incomplete gear, which gets into meshed connection to a gear rack II, is rotatably arranged at the lower side of the gear rack II; a reset spring I is horizontally fixedly arranged between a sleeve plate and the vertical fixed plate; a screw lead gets into horizontal threaded connection to the sleeve plate in a penetrating mode; the left end of the screw lead is rotatably connected to a limiting plate; and a twisting block is fixedly arranged at the right endof the screw lead. According to the service device provided by the invention, impact throwing of tennis ball is achieved by rapid sliding of a push plate leftwards in the horizontal conveying pipe, so that workload of manual ball throwing is greatly reduced; and meanwhile, throwing force of the tennis ball can be adjusted, so that operations become simple and convenient, and athletes are facilitated in tennis ball hitting training to a great extent.
