         12 . The packing box of  claim 11 , further comprising:
 a surrounding multi-plate reinforcement, configured in the outer box, and surrounding the first supporting frame and the second supporting frame.   
     
     
         13 . The packing box of  claim 12 , wherein the outer box has a U-shaped slit located on a sidewall, and a portion of the sidewall surrounded by the U-shaped slit is folded to form a first opening, and the surrounding multi-plate reinforcement has a second opening corresponding to the first opening. 
     
     
         14 . The packing box of  claim 11 , wherein the substrate of the first supporting frame is the same to the substrate of the second supporting frame, and a configuration position of the cushion assembly of the first supporting frame on the substrate of the first supporting frame is the same to a configuration position of the cushion assembly of the second supporting frame on the substrate of the second supporting frame. 
     
     
         15 . The packing box of  claim 11 , wherein each of the substrates comprises a plurality of sidewalls surrounding a periphery of the bottom plate, and the plurality of sidewalls surround the first portion of the cushion assembly.
