Meanwhile, in the enterprise production, a test method for detecting the mechanical property of a stud welding joint is usually a torsion test, namely, the torsion of a stud is measured by twisting the stud by a precise digital torque wrench, the test method is single, and data comparison with other mechanical property test methods is lacking, so that it becomes important to design a corresponding clamp to test the tensile mechanical property of stud welding. In addition, due to the uniqueness of the shape of the stud welding tensile sample, the diameter of the stud is smaller and the stud is provided with threads, so that the conventional clamp type tensile clamp cannot be used normally, if the clamping problem of the stud is solved by changing the size of the clamp head, the original clamp needs to be disassembled and a new clamp needs to be redesigned, and thousands of elements are needed for the new clamp, so that the time and the labor are consumed, and the follow-up work of a tensile test can be influenced. Meanwhile, in a plate tensile test, when the plate cannot be fastened by the clamping head and the slipping phenomenon occurs due to insufficient stress, the problem of slipping of the plate in the tensile process is effectively solved by punching two ends of the plate and fixing the plate by using a screw rod. Similar to the stretching of a plate, the bar can also have the inconvenient clamping phenomenon of a sample in the stretching test process, and the clamp provided by the invention is effectively matched with threads at two ends of the bar through the cylindrical groove with threads and the hollow cylindrical small part, so that the inconvenient clamping problem of the bar in the stretching process is solved.
