Thermal simulation torsion experiment clamp and use method

The invention relates to a thermal simulation torsion experiment clamp and a use method, and belongs to the technical field of thermal simulation experiment devices. The thermal simulation experiment device mainly solves the technical problem that an existing thermal simulation experiment device cannot perform tension, compression and torsion functions in the same mechanical system. The technical scheme of the invention provides a thermal simulation torsion experiment fixture. The thermal simulation torsion experiment fixture comprises a left fixture plate and a right fixture plate which are oppositely arranged, and a sample mounting fixture head arranged between the left fixture plate and the right fixture plate, the left end of the left clamp plate is arranged on a left fixing device of the thermal simulation torsion experiment device, and the right end of the right clamp plate is arranged on a right fixing device of the thermal simulation torsion experiment device; and clamping plate racks are arranged on
