Sample tool for high-temperature tensile test of metal material

A sample tool for a high-temperature tensile test of a metal material belongs to the technical field of metal material performance test equipment and is used for performing the high-temperature tensile test on the metal material. According to the technical scheme, a clamping rod is a cylinder, a sample table is a cuboid, the front end of the cylinder of the clamping rod is fixedly connected with a moving head of the high-temperature tensile testing machine, the rear end of the clamping rod is fixedly connected to the center of the front end face of the sample table, and a sample groove is formed in the middle of the upper end face of the sample table and is a rectangular groove; a communicating groove is formed between the rear end of the sample groove and the rear end face of the sample table, the communicating groove is opened in the rear end face of the sample table, the width of the communicating groove is smaller than that of the sample groove, the depth of the sample groove is matched with the thickness
