The invention discloses a spliced type outdoor display screen structurally comprising a protection plate, a controller, a rotating rod, gap rotating teeth, an adjusting device, an elastic rod, displayscreen bodies, a frame body and a supporting rod; after the improvement, when the spliced type outdoor display screen is used, the display screen bodies are buckled on a positioning frame in parallel; supporting push blocks are connected to the rear portions of the display screen bodies, and adsorption strips can be mounted on the display screen bodies due to the acting force of the supporting push blocks; suckers can firmly adsorb the display screen bodies without loosening due to the strong adsorption force of bionic octopus, so the display screen bodies can be stably mounted on the positioning frame, and the use stability of the display screen bodies is improved. The position of a swing rod is adjusted left and right on a dial through a rotating shaft, after the swing rod is adjusted to a certain position on a sliding rail, the inner wall of a buckle is matched with an elastic buckle, the elastic buckle is fixedly clamped on a lock catch, the flatness, perpendicularity and levelness of spliced display screen bodies are located on the same plane, and the display effect of the display screen is improved.
