The utility model discloses a test sample clamping mechanism which comprises a fixing part, a clamping part and a driving part, wherein the fixing part is fixed on a movable cross beam of a tensile testing machine, two inner end surfaces of the fixing part are inverted V-shaped inclined surfaces, the driving part is propped on the clamping part, and the clamping part can freely move along the inverted V-shaped inclined surfaces of the fixing part; the test sample clamping mechanism also comprises auxiliary driving parts, wherein the auxiliary driving parts are strip-shaped and are horizontally and symmetrically installed on the driving part, and the outer end surfaces of the auxiliary driving parts are respectively in contact with the inner end surface of the clamping part. The test sample clamping mechanism transfers the horizontal acting force of the clamping part through the auxiliary driving parts, so that the clamping part cannot generate the longitudinal acting force to the elongated test sample, and th
