The invention relates to the field of aero-engine case assembly, and discloses a supporting plate nut adjusting type riveting tool suitable for a thin-wall case. A pressing rivet assembly adopts an adjusting screw rod of a hollow structure, so that position rough adjustment and clamping and positioning of a part to be riveted can be achieved; it can be guaranteed that in the riveting process, the riveting pressing head and a riveting hole of the supporting plate nut are oriented and do not deviate, and the riveting quality is improved; the riveting pressure head and the force application bolt which are located in the hollow structure are isolated through the steel ball to form a split type force transmission assembly, the steel ball is in point contact with the force application bolt and the riveting pressure head, the situation that the force application bolt rotates to drive the riveting pressure head to rotate can be prevented, and rotating torque is almost completely converted into extrusion force; extrus
