Each movable swivel foot 10 is movably connected to the threaded adjustment rod 9 through a hinge. The connecting soft belt 11 is cross-shaped, and each movable swivel foot 10 is connected to the connecting soft belt 11. When the movable swivel foot 10 is opened, the connecting soft belt 11 is stretched and tightened, so that the movable swivel foot 10 maintains a certain opening angle, thereby facilitating the support of the entire device, and the threaded adjustment rod 9 can also be rotated to adjust the relative position between the threaded adjustment rod 9 and the rotating drum 8, so as to facilitate the practitioner to adjust the height position of the first plate body 1 as needed.

It should be noted that the above-mentioned structural components are all common metal parts or plate parts, which are convenient for research and development and manufacturing, and the actual dimensions can be adjusted according to needs during actual production.

The working principle of the utility model is as follows: first, the rotating drum 8 is rotated to a position perpendicular to the first plate body 1, and then the fastening screw sleeve 15 is rotated so that the fastening screw sleeve 15 is pressed against the anti-skid rubber pad 16, so that the shaft body 13 and the rotating drum 8 can be fixed relative to the shaft frame 12, and at the same time, the movable rotating foot 10 at the bottom of the threaded adjustment rod 9 is opened to support the entire device, and the threaded adjustment rod 9 can also be rotated to adjust the relative position between the threaded adjustment rod 9 and the rotating drum 8, so that the practitioner can adjust the height position of the first plate body 1 according to the needs;

The first plate 1 is kept in a horizontal position, and the second plate 3 is kept in a vertical position. Then, the practitioner hits the table tennis ball 7 with a racket to practice swinging. When the table tennis ball 7 is hit, the spring rod 5 is bent, and then the table tennis ball 7 rebounds by the rebound force, which is convenient for repeated hitting. At the same time, the mirror 4 on the second plate 3 is convenient for the practitioner to observe his own movements, so as to adjust his swinging movements in time and avoid the posture being not in accordance with the standard.

When the entire device needs to be folded for storage or carrying, loosen the fastening screw sleeve 15, then rotate the rotating drum 8 to fit the bottom of the first plate body 1, and rotate the threaded adjustment rod 9 to be stored in the rotating drum 8, then separate the rubber rod head 6 from the positioning socket 17, and then fit the ping-pong ball 7 into the fitting groove 18, and then rotate the first plate body 1 to fit onto the second plate body 3 for folding, so that the ping-pong ball 7 and the mirror 4 are both between the first plate body 1 and the second plate body 3, so that they are protected and prevented from damage, and folded and stored, which is convenient for carrying and moving.
