[0004] However, the opening size of the traditional silicon core pipe tensile test clamp is fixed, and it can only be used for testing silicon core pipes of specific diameters, which cannot meet the diversified test requirements. Some adjustable clamps have complicated and inaccurate adjustment methods, which may require multiple tools for multiple measurements and adjustments, not only consuming time, but also being difficult to ensure that the opening size after each adjustment can accurately fit the diameter of the silicon core pipe, resulting in loose or tight clamping, affecting the reliability and repeatability of the test results, and when clamping the silicon core pipe, there is a lack of effective protection measures for the pipe material, which is easy to cause damage to the surface of the silicon core pipe. For example, some clamps use hard materials to directly contact the silicon core pipe, which will scratch the surface of the pipe during clamping. During the stretching process, the damage will be further aggravated with the change of friction and pressure.
