description The invention discloses a standard distance section positioning device for a thin-walled tubular fatigue specimen, and relates to a testing device. The standard distance section positioning device is characterized by comprising a base (1), a mold (2), a right cover plate (3), the specimen (4), a rod (5) provided with threads at two ends, a dotter (6), nuts (7), screws (8) and an upper cover plate (9), wherein the specimen (4) is arranged in the mold (2) of the base (1), the mold (2) cooperates with grooves in the base (1), the specimen (4) is axially positioned by the right cover plate (3), the upper cover plate (9) and the mold (2) are fixed through the screws (8), the rod (5) provided with the threads at the two ends penetrates into a thin-walled tube, ends of the rod (5) provided with the threads at the two ends are locked through the nuts (7), the base (1), a left cover plate and the right cover plate (3), and the dotter (6) cooperates with dotter holes. The size of a standard distance section of the thin-walled tubular specimen is determined accurately, so that a more accurate testing result is obtained.
