Zusammenfassung:The utility model discloses a detachable rock variable-angle shear test device with low frictional resistance, and relates to the technical field of rock shear tests. The shearing device comprises an upper shearing seat and a lower shearing seat. The rolling balls are embedded between the inner plastic plate and the outer plastic plate and are fixed through the bolts, and then the rolling balls extending out of the two sides of the inner plastic plate and the two sides of the outer plastic plate are attached to the single-face magnetic sliding rails and the pressing plate sliding rails respectively, so that position limitation of the rolling shaft comprising the rolling balls, the inner plastic plate and the outer plastic plate is completed. Therefore, in the extruding and shearing process, the friction force is reduced when the upper shearing seat and the pressing plate as well as the lower shearing seat and the pressing plate slide by utilizing the fitting of the balls and the single-sided magnetic slide ra
