Wall decoration device

The invention relates to the field of appliances for building decoration engineering, in particular to a wall decoration device which is provided with a square frame, an operation tail end, eight cable pieces and eight winding and unwinding assemblies. A square space is defined by the spliced square frame; the operation tail end is located in the square space. The first tail ends of the eight cable pieces are connected with the operation tail end, and the second tail ends of the eight cable pieces are connected with the eight winding and unwinding assemblies correspondingly. The winding and unwinding assembly is used for winding or unwinding the cable piece. And the extension directions of the eight cable pieces in the square space respectively point to eight vertexes of the square frame. Supporting is provided for the operation tail end through the cable piece and the square frame, the square frame corresponds to the whole ground of the space needing decoration, the gravity center of the wall decoration devi
