A mounting structure capable of supporting multiple types of supports comprises a first support and a second support. The first support comprises a cross beam, hoisting supporting pieces, supporting frames and a self-locking buckle, wherein the supporting frames and the self-locking buckles are arranged on a side face plate of the cross beam. The hoisting supporting pieces are inserted into the ends of the cross beam. The second support comprises a fixed plate, mounting frames arranged on the outer side of the fixed plate and adaptive to the supporting frames and a self-locking boss adaptive to the self-locking buckle. The mounting frames are inserted into the supporting frames, so that the first support is fixedly connected with the second support. The self-locking buckle and self-locking boss are in buckled connection. Compared with the prior art, the mounting structure is simultaneously suitable for mounting of multiple types of supports, mounting is simple and convenient, disassembling and assembling do not need a tool, and maintenance is simple and convenient. The first support and the second support achieve self-locking, the structure is firm, fall-off is avoided, and safety is guaranteed
