The invention especially relates to a stepless speed-changing and turning vertical shaft straight wing propeller mainly comprising a U-shaped pipe operation control system, oval control discs, a straight rail round disc, a box type rotating disc, T-shaped connection rods and straight wing blades, etc. The stepless speed-changing and turning vertical shaft straight wing propeller is characterized in that the U-shaped pipe operation control system controls the oval control discs to rotate and horizontally move; the straight rail round disc is placed in the middle of the box type rotating disc; the two oval control discs are clamped between the straight rail round disc and the box type rotating disc; the two oval control discs are fixedly connected to centers of the straight rail round disc and the box type rotating disc and can rotate and translate in a certain range; one end of each T-shaped connection rod is perpendicularly fixed to a slide shaft; the middle of the slide shaft is embedded into the straight rail; two ends of the slide shaft are respectively embedded into oval control tracks and the slide shaft can slide along the tracks; the other end of each T-shaped connection rod is connected with a swinging arm of each straight wing blade; the box type rotating disc rotates to drive the straight wing blades to rotate and drive the slide shafts to move along the straight rail and the oval control tracks; each T-shaped connection rod drives the straight wing blades to swing; and thrust is produced during swinging and rotation of the straight wing blade, so stepless speed-changing and turning operation can be achieved.
