Abstract: Provided are a tension-torsion loading tooling, and a tension-torsion loading test system thereof, belonging to the technical field of material testing. The tension-torsion loading tooling includes a connector, a clamping head, and a connecting rod assembly. The connecting rod assembly includes four horizontal connecting rods, and four inclined connecting rods, the four horizontal connecting rods are sequentially hinged from end to end to form a parallelogram structure, and each of four diagonal corners of the parallelogram structure is hinged with one end of each of the four inclined connecting rods. The other ends of two inclined connecting rods on the diagonal corners are hinged with the connector, and the other ends of the other two inclined connecting rods are hinged with the clamping head. The tension-torsion loading test system includes a tensile testing machine, and a tension-torsion loading tooling.
