         5 . The combination drawer of  claim 1 , wherein the second outer plate and the second inner plate of each of the side panel modules are combined together by ultrasonic waves. 
     
     
         6 . The combination drawer of  claim 1 , wherein the first inner plate of the front panel module has a surface provided with a plurality of reinforcing ribs abutting the first outer plate. 
     
     
         7 . The combination drawer of  claim 1 , wherein the rear panel has an outer surface provided with a plurality of reinforcing ribs. 
     
     
         8 . The combination drawer of  claim 1 , wherein the second inner plate of each of the side panel modules has a surface provided with a plurality of reinforcing ribs abutting the second outer plate. 
     
     
         9 . The combination drawer of  claim 1 , wherein each of the bottom panels has an outer surface provided with a plurality of reinforcing ribs. 
     
     
         10 . The combination drawer of  claim 1 , wherein
 each of the first connecting section of the front panel module and the second connecting section of the rear panel is a substantially T-shaped slot which has an outer side provided with an enlarged entrance;   the third connecting section of each of the side panel modules is a substantially T-shaped plug which is inserted through the enlarged entrance into each of the first connecting section of the front panel module and the second connecting section of the rear panel and is locked in each of the first connecting section of the front panel module and the second connecting section of the rear panel.   
     
     
         11 . The combination drawer of  claim 3 , wherein
 the coupling portion of a first one of the bottom panels is provided with a locking groove;   the coupling portion of a second one of the bottom panels is provided with a locking hook inserted into and locked in the locking groove of the first one of the bottom panels so that the first one of the bottom panels is connected with the second one of the bottom panels.
