The utility model discloses a model demonstration instrument accessory in the technical field of model demonstration devices. The model demonstration instrument accessory comprises a base; a mounting seat; a fixing column; a first sphere; a support bar; a second sphere; and the rotating part is used for driving the supporting rod to rotate around the first ball and can drive the second ball to rotate in the circumferential direction. The first sphere is analogous to the sun, the second sphere is analogous to the earth, the supporting rod is driven by the rotating part to rotate, so that the second sphere can rotate around the first sphere, revolution of the earth around the sun can be demonstrated, in addition, the supporting rod rotates synchronously, and the second sphere can rotate around the axis of the second sphere. An included angle is formed between the axial direction of the supporting rod and the axial direction of the rotating sleeve, so that the rotating shaft is in an inclined state when the seco
