Description

Technical Field

[0001] This utility model relates to the field of mechanical property testing technology, specifically to a tooling for measuring gauge length of mechanical properties. Background Technology

[0002] Elongation after fracture is one of the key indicators for measuring the plastic deformation capacity of a material. It is usually measured by manually marking points and then measuring the gauge length of the fractured specimen with simple measuring tools such as calipers.

[0003] In terms of measurement efficiency, manual measurement is quite cumbersome, especially when there are many specimens to be tested, consuming a lot of manpower and time. Furthermore, for specimens with complex shapes or tiny dimensions, it is extremely difficult, if not impossible, to manually mark and measure the gauge length accurately.

[0004] Therefore, there is an urgent need for a gauge length measuring tool that is accurate and efficient. Utility Model Content
