Zusammenfassung:	An adjustable rotary structure comprises a first restricting assembly, a second restricting assembly, a rotary member and a positioning seat. The rotary member is formed with a restricting hole and a shift hole. The positioning seat is formed with a positioning groove, a restricting circular groove and a restricting elliptic groove. The first restricting assembly is positioned on the positioning groove by the restricting hole in such a manner that the restricting hole of the rotary member abuts against the positioning groove and is restricted on the positioning seat. The second restricting assembly is selectively positioned in the restricting circular groove or the restricting elliptic groove via the shift hole, so that the rotary member is forced to rotate along a circular path or an elliptic path.
