Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a tensile machine for testing the ductility of plastic rods. One of the purposes is to ensure that the plastic rods will not be damaged when they are clamped, so that the overall integrity of the rods can be maintained and the tensile force can be solved. When the plastic rod is clamped by the machine, the clamped parts of the two ends of the plastic rod will be deformed and damaged due to the clamping of the clamp, and its overall integrity will be destroyed. When performing a tensile test, it is easy to cause the overall force to be weak. Balanced, causing the plastic rod to break from both ends, which affects the test results; another purpose is to solve the problem that due to the material of the plastic rod itself, when the stress inside it is stretched to the threshold, it will not break. Make a sound, but the machine cannot remind the staff in time to stop the control device, and the machine will easily cause damage to itself if it continues to run, and will affect the test results, so as to achieve the effect of accurately collecting test data
