The utility model particularly relates to a continuous biaxial stretching one-step blow molding mechanism, belonging to the technical field of bottle blowing equipment. It comprises a plastic extruder, a die head, a blowing needle, a bottle blowing mold and a rotating device. The bottle blowing mold is mounted on the rotating device, which includes a driving wheel and a chain conveyor with multiple mold clamping components. A non-constant speed rotation module is arranged on the rotating device. The utility model greatly improves the strength, toughness and transparency of extrusion blow molded products without increasing raw material usage. Biaxially stretched polypropylene blow molded products with higher strength and transparency can be obtained with material saving. The drop resistance is improved from 1 meter to 1.8 meters, and the blowing speed reaches over 300 bottles per minute, greatly enhancing production efficiency.
