A supporting structure comprises a supporting arm (1), a supporting decorative element (2) and a supporting resist sheet (3). The supporting arm (1) is connected to the supporting resist sheet (3) through the supporting decorative element (2) between them. A dummy club (101) which provides with screw holes (103) and projecting lock legs (102) is formed on front end of the supporting arm (1). The supporting resist sheet (3) has screw holes (301) corresponding to the screw holes (103) and lock holes (302) corresponding to the projecting lock legs (102). After the supporting decorative element (2) is covered on the dummy club (101), the supporting resist sheet (3) is fixed on the dummy club(101) by screws (4). The mounting manner of the structure is simple and the angle of the supporting structure can be freely adjusted through the supporting decorative element.
