The invention relates to a bidirectional follow-up loading test device suitable for a linear transmission mechanism, and belongs to the field of aerospace equipment. Comprising a rack, an upper-layer guide assembly, a linear transmission part, upper-layer transverse loading equipment, vertical loading equipment, a lower-layer guide assembly, lower-layer transverse loading equipment, a locking device and a tested piece, loads are applied through bidirectional coupling in the transverse direction and the vertical direction, the non-linear and non-continuous aerodynamic load working condition borne by the telescopic wing driven by a linear transmission mechanism can be equivalently simulated, and the independent loading function in the transverse direction and the vertical direction can also be achieved. Through the mode of combined guiding of the upper layer and the lower layer and common loading of the two electric cylinders, the supporting rigidity of the test device is improved, and redundant force of the test device in the vertical direction is also eliminated; the device has a function of locking a tested piece at a specified position, and can be used for testing the locked-rotor capability of the tested piece at multiple positions.
