Summary:The invention relates to the technical field of metal material detection, in particular to a tensile test tool for ultrahigh-strength steel. Comprising an upper tool and a lower tool, the upper tool and the lower tool are each composed of a clamping part and a sample connector, internal threads are machined in the centers of the sample connectors, and the sample connectors of the upper tool and the lower tool are in threaded connection with a tensile sample. The upper tool and the lower tool are the same in shape and size. After clamping, the axial direction of the sample and the tool can completely coincide with a test force action line. And the cross section area of the clamping part is circular. And the size of the circular clamping part is not less than 60mm. The tool is made of 406 materials. The stretching tool is used for carrying out a stretching test on the stretching sample of the ultra-high-strength steel screwed joint, the clamping mode is simple and convenient, the speed is high, the tool error i
