| Zusammenfassung: | The utility model discloses a tensile testing machine and a clamp thereof. The tensile testing machine comprises two first connecting rods, two second connecting rods and middle connecting rods. One ends of the two first connecting rods are hinged to a chuck strut and symmetrically distributed on two sides of the chuck strut. One ends of the two second connecting rods are respectively hinged to the other ends of the two first connecting rods, chucks are respectively hinged to the other ends of the two second connecting rods, and the inclined angle formed by the second connecting rods and the first connecting rods which are hinged to the second connecting rods is smaller than 90 degrees. The middle connecting rods are respectively hinged to the two second connecting rods. When the chuck strut is drawn, the chuck strut drives the first connecting rods to rotate around a hinge point which is formed by hinge of the first connecting rods and the second connecting rods. Along with the rotation of the first connecti |
