The invention discloses a critical current test sample rod for a straight short sample superconducting wire in a multi-angle field. The critical current test sample rod comprises two current leads. An epoxy sheath wraps the two current leads. One end of the epoxy sheath is provided with a sealing flange. The inner walls of both ends of the epoxy sheath are provided with bakelite support rings respectively. Low-temperature epoxy glue is disposed between the outer walls of the two current leads and the inner walls of the two ends of the epoxy sheath. The two current leads both extend out of the epoxy sheath. The ends of the two current leads, without a sealing flange, are connected to two lower-end current leads. The other end of each lower-end current lead is fixed to an epoxy supporting plate. The critical current test sample rod is suitable for an experiment testing the performance of a superconductive strand, and no such similar structure exists in China. The structure enables reliable contact at low temperature, allows heavy currents, is easy to operate when a sample is replaced, and will not damage a superconducting wire.
