description The utility model relates to the field of computer accessories, in particular to a rotary positioning device and a notebook computer. The rotary positioning device comprises a first positioning piece,a second positioning piece and a positioning ball; a first positioning groove is formed in the end, close to the second positioning piece, of the first positioning piece. A second positioning grooveis formed in the end, close to the first positioning piece, of the second positioning piece. The end, close to the first positioning piece, of the positioning ball is arranged in the first positioninggroove, and the end, close to the second positioning piece, of the positioning ball is arranged in the second positioning groove. When the first positioning groove and the second positioning groove are staggered, locking of bidirectional rotation is conducted through the positioning balls, continuous rotation of the notebook computer is avoided, winding of the connecting wire is avoided, the service life of the connecting
