 a second unfolded plane connected to the first side wall and extending along a lengthwise direction of the first side wall, wherein the second unfolded plane is provided with folds, and the second unfolded plane forms a bottom plate, a second side wall and a top cover of the packaging box after being assembled along the folds.   
     
     
         7 . The packaging box unfolded plate according to  claim 6 , wherein the bottom plate is a square. 
     
     
         8 . The packaging box unfolded plate according to  claim 7 , wherein the first side wall faces to the second side wall after the packaging box is assembled. 
     
     
         9 . The packaging box unfolded plate according to  claim 8 , wherein a base is disposed on a first surface of the bottom plate of the second unfolded plane and a positioning piece is disposed on a first surface of the top cover of the second unfolded plane. 
     
     
         10 . The packaging box unfolded plate according to  claim 8 , wherein the second unfolded plane is connected to a first end of the first side wall; and
 an outer side cover is disposed on a side of the top cover and fitted with a second end of the first side wall.   
     
     
         11 . The packaging box unfolded plate according to  claim 10 , wherein a first magnet is disposed on an edge of the outer side cover and is attracted to a second magnet disposed on the first side wall. 
     
     
         12 . The packaging box unfolded plate according to  claim 8 , wherein two opposite edges of the first unfolded plane, which are parallel to the lengthwise direction of the first side wall, are fastened to form the four side walls of the packaging box. 
     
     
         13 . An assembling method for a packaging box, comprising: providing a first unfolded plane and a second unfolded plane connected to the first unfolded plane, wherein the first unfolded plane is provided with folds; assembling the first unfolded plane along the folds and fastening two sides of the first unfolded plane to form four side walls of the packaging box, wherein one of the four side walls is a first side wall, and the two sides are parallel to a lengthwise direction of the first side wall;
 assembling the second unfolded plane along folds to form a bottom plate, a second side wall and a top cover of the packaging box; wherein the second unfolded plane extends along the lengthwise direction of the first side wall and is provided with the folds; and   connecting the four side walls, the bottom plate, the second side wall and the top cover to form the packaging box.   
     
     
         14 . The method according to  claim 13 , wherein the bottom plate of the packaging box is a square. 
     
     
         15 . The method according to  claim 13 , wherein the first side wall of the packaging box faces to the second side wall. 
     
     
         16 . The method according to  claim 13 , further comprising: disposing a base on a first surface of the bottom plate of the second unfolded plane; and disposing a positioning piece on a first surface of the top cover of the second unfolded plane. 
     
     
         17 . The method according to  claim 13 , wherein the second unfolded plane is connected to a first end of the first side wall; the packaging box further comprises an outer side cover disposed on a side of the top cover, and the top cover is configured to fit with a second end of the first side wall.
