The instrument is a set of products through the combination of a variety of components. It is a new type of test apparatus that can complete both the mechanical property test of rock and the mechanical property of soil. The apparatus adopts the flat push method and is mainly applicable to the direct shear test of rock masses, structural surfaces (such as joint surfaces, layer surfaces, sheet surfaces, incised surfaces and other locations) and concrete (or mortar) and rock contact surfaces (cemented surfaces), as well as the shear strength test of the combined surfaces of concrete and other materials or the whole.

The instrument structure is simple, light, intuitive, easy to maintain, can be used in the field, test data digital display, test results are accurate and reliable.
