Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-3, the utility model provides a technical solution: a portable tennis training device, including a base 1 and a training device body 4, the center of the upper surface of the base 1 is fixedly installed with a fixed column 2, so A lifting rod 12 is plugged inside the fixed column 2, a rack 13 is fixedly connected to one side of the lifting rod 12, a gear 11 is meshed on one side of the rack 13, and a penetrating rod 11 is fixedly connected to the center of one side of the gear 11.
