       8 . The packaging container of  claim 1 , wherein the first and second receiving space partially overlap with each other. 
   
   
       9 . The packaging container of  claim 1 , further comprising an upper cover for covering the protection structure. 
   
   
       10 . The packaging container of  claim 9 , wherein a bottom of the upper cover is flat. 
   
   
       11 . The packaging container of  claim 9 , wherein the upper cover has auxiliary fixing pieces provided thereon. 
   
   
       12 . The packaging container of  claim 11 , wherein the auxiliary fixing pieces comprise protruding pieces. 
   
   
       13 . The packaging container of  claim 11 , wherein the auxiliary fixing pieces comprise a first type of protruding piece, and the first type of protruding piece has a thickness substantially equal to the height difference between the height of the top of first products and the height of the top of walls of the packaging container after the first products are placed into the first receiving space. 
   
   
       14 . The packaging container of  claim 13 , wherein the auxiliary fixing pieces further comprise a second type of protruding piece, and the second type of protruding piece has a thickness substantially equal to the height difference between the height of the top of second products and the height of the top of walls of the packaging container after the second products are placed into the second receiving space. 
   
   
       15 . The packaging container of  claim 13 , wherein the first and second receiving space partially overlap with each other, and the first protruding piece is shaped so that the first type of protruding piece is accommodated in the first receiving space without occupying the partially overlapped space.
