The utility model discloses an adj. Tabular sample tension clamp, its characterized in that, these anchor clamps include: the anchor clamps bodies (3, 5), its one end is equipped with cotter hole (7) to be connected with tensile testing machine connecting rod (1, 6) through pin (2), be used for guaranteeing the axis coincidence of test pulling force, anchor clamps and test piece, the other end of the anchor clamps bodies (3, 5) is equipped with a longitudinal Groove who runs through anchor clamps, the bottom of recess is sample cell (8), and the thickness of width ratio test piece (4) of sample cell (8) is big slightly for it can put into to guarantee sample (4) tensile test carries out in the anchor clamps bodies (3, 5). The utility model discloses a tensile test can be carried out to the sample of various high strength, high rigidity and difficult processing through be equipped with a longitudinal Groove who runs through anchor clamps at the specific tip of clamp to the scheme.
