The utility model relates to a tennis training device which comprises a base, universal wheels, an auxiliary rod, a supporting rod, a moving rod, a limiting rod, a buffering mechanism and a training frame. Through the arranged buffer mechanism, when the training frame is impacted by a tennis ball, the training frame drives a limiter and a supporting plate to slide in an assembling body and extrudes a damper backwards, so that the right end of the damper extrudes a first spring, the damper and the first spring play a resistance role, and the damper is driven to reset under the elastic effect of the first spring; by rotating a connecting rod, the connecting rod and a threaded plate are rotated in a threaded mode, when a limiting block slides to the vertical part of a limiting groove, the connecting rod is just screwed out of the threaded plate, and when the limiting block slides to the vertical part of a limiting groove, the connecting rod is just screwed out of the threaded plate; under the elastic action of a
