[0002] Engineering is a general term for the science and technology used to construct various land engineering facilities, including houses, roads, railways, pipelines, tunnels, bridges, offshore platforms, water supply and drainage, and protective projects. When selecting materials before construction, it is necessary to conduct various tests on various materials, such as hardness.

[0003] Engineering material sample testing is to place the sample to be tested in a designated position and perform multi-faceted testing using instruments. However, some existing engineering material sample testing devices do not have a structure to clamp and fix the material. When testing the hardness of the material, the test is often performed in a downward pressure manner. During the downward pressure, the material usually shakes and moves, thereby affecting the accuracy of the sample testing and reducing work efficiency. In response to the above problems, the inventors proposed an engineering material sample testing device to solve the above problems. Utility Model Content
