The invention provides a crushing test device considering a spatial constraint state. A constraint situation of a particle test sample in a space can be truly reflected, and a particle local constraint state under a three-dimensional space constraint state condition is researched. The invention provides the crushing test device which is characterized by comprising an installation and support part, a pressing part, a longitude adjusting part, a track part, a clamping constraint part and a test part, wherein the installation and support part is provided with an upper installation unit, a lower installation unit and a support unit; the pressing part is installed on the installation and support part, and is provided with a drive unit, a force application unit and a sample placement unit; the longitude adjusting part is provided with an upper annular slide rail and a lower annular slide rail; the track part is provided with an annular fixed track and at least one semi-annular slidable track; the clamping constraint part is provided with at least one clamping constraint component and used for constraining a test sample; the test part is connected with the pressing part, and used for collecting pressure applied on the test sample through the pressing part and displacement during a pressing process, and processing to obtain a corresponding test result.
