Tensile testing is a routine test for physical property testing of steel products, the most important of which is elongation after break. In the process of measuring the elongation after fracture of the sample, for a tensile testing machine which must manually measure the gauge length after fracture, two fracture parts of the sample need to be manually butted together and measured by a measuring tool caliper. In the measuring process, the caliper touches the test sample, so that the position of the test sample moves, the test sample needs to be butted again, and particularly, the test sample is a wire rod test sample with a round section and easy to roll, and the operation is more difficult. Not only wastes time, but also causes inaccurate measurement and influences the calculation result of the elongation after fracture. In the sample butt joint process, the coaxiality of the stretched sample can be maintained, and the coaxiality is also one of factors influencing the sample measurement accuracy. Therefore, it is necessary to design an auxiliary device for manually measuring the elongation after fracture of the tensile sample, so as to improve the accuracy and the working efficiency of the measurement of the elongation after fracture.
