The invention relates to the technical field of model display, in particular to a cartoon game character model display device which comprises a supporting module, the supporting module is movably connected with four display modules in a clamped mode, the supporting module comprises a bottom plate, and a second annular groove is formed in the top face of the bottom plate. The inner side face of thesecond annular groove is slidably connected with four second arc-shaped blocks corresponding to the four display modules, and a supporting rod is arranged on the top face of the bottom plate. According to the invention, through sliding connection between the clamping rods and the clamping grooves, a model can be placed on the fixing blocks to be fixed, and then the clamping rods can be separatedfrom the clamping grooves, so that the positions of the fixing mechanisms can be adjusted, the distance between two adjacent fixing mechanisms can be adjusted according to the size of the model; and meanwhile, the position of the display rod can be rotated, and the distance between every two adjacent display modules is adjusted, so that the display space can be saved; and when the model is large,the corresponding display space can be adjusted for display, and use is convenient.
