The invention relates to an internal supporting device of a model. The internal supporting device is characterized by comprising a base, a transmission gear, a driving gear, driven gears, at least two supporting rods and supporting arms, wherein the transmission gear is of a circular ring structure; an inner tooth is arranged on the inner side of the circular ring structure; outer teeth are arranged on the outer side of the circular ring structure; the driving gear is meshed with the inner tooth; the driven gears are meshed with the outer teeth; the at least two supporting rods are symmetrically arranged in the direction where the diameter of the circular ring structure is positioned; meshing teeth are arranged on one surface, which is in contact with the corresponding driven gear, of each supporting rod and are meshed with the driven gears; and the supporting arms are arranged at the outermost ends of the supporting rods. Expansion and contraction of the supporting rods drive the supporting arms at the outermost ends of the supporting rods to outwards expand to realize a supporting state in the model; the driving gear is rotated towards the reverse direction, and the supporting rods can be shortened and contracted, so that the supporting device can be conveniently taken out; and the internal supporting device of the model is simple in structure, convenient to operate and good in supporting effect.
