The utility model belongs to the technical field of rock testing, particularly discloses a rock pure shear testing machine under one-way compression, and aims to simplify the structure and save the cost by being matched with equipment capable of providing axial pressure for use. The testing machine can drive the first rack and the second rack to synchronously move up and down through the pressed connecting rod of the power conversion mechanism, so that the testing machine can be matched with a pressing rod of equipment capable of providing axial pressure through the pressed connecting rod, and the axial pressure provided by the equipment is used as power for driving the first rack and the second rack to synchronously move; under the driving of equipment for providing axial pressure, the power conversion mechanism can drive the left sample fixing head and the right sample fixing head to rotate in opposite rotating directions, so that torsional moment can be applied to the rock sample fixedly mounted between th
