The invention relates to a tension-torsion composite clamp under a multi-physics coupling condition, and relates to the technical field of material tests. The rear end of a constant speed hydraulic cylinder is connected with a tension-torsion composite sensor, and the end surface of a piston rod on the front end of the constant speed hydraulic cylinder is coated with a high-temperature ceramic insulating material; a heat insulation part comprises a connecting screw and a rubber insulating mat and is composed of mica sheets and copper sheets in an overlaying manner; the clamp is used for connecting a front-end flange, a positioning piece, the heat insulation part and a clamping part of the constant speed hydraulic cylinder together through bolts, and a wedge block is used for clamping a test specimen under the thrust action of the constant speed hydraulic cylinder; a spline pair is arranged between the front end of the piston rod and a clamp body, and is used for preventing relative rotation of the piston rod
