Zusammenfassung:	The utility model relates to a quick scriber for a tensile test piece, which consists of an upper semi-circular ring, a connecting rod and a lower semi-circular ring, wherein the inner aperture D of the upper semi-circular ring is equal to that of the lower semi-circular ring, and the connecting line between the centers of the circles of the upper semi-circular ring and the lower semi-circular ring is parallel to the connecting rod; the inner aperture D of the semi-circular rings is equal to the sum of the external diameter d of the tensile test piece and (0.1-0.4mm); and the distance H between the upper plane of the upper semi-circular ring and the lower plane of the lower semi-circular ring is equal to the gauge length L0 of the tensile test piece. The quick scriber is simple in structure, convenient to use, rapid in scribing and smaller in error.
