[0003] A hardness testing device for construction materials is disclosed in the Chinese utility model patent application disclosure CN 218481353 U. The device can place three groups of materials at the same time by means of three groups of supports arranged on the top plate, and can detect them simultaneously in cooperation with the contact head. The height of the connecting plate can be detected by the electric telescopic rod, so that the forces on the three groups of materials are consistent, and the scratch resistance of the material surface and the deformation stress of the whole material can be detected at the same time. It is not only efficient, but also convenient for comparison, which is conducive to improving the effect of equipment use. However, in construction engineering, there are many construction materials that need to be tested for their hardness, such as hard materials such as walls mixed with concrete.
