 a door body sealing assembly including a rotating shaft rod; and 
 a handle operably coupled to the door body sealing assembly and including an inner sidewall and a plug; and 
   a container body including a fixing part and a sliding part.   
     
     
         9 . The vacuum preservation device of  claim 8 , wherein the rotating shaft rod of the drawer body sealing assembly is operably coupled to the first fixing fastener of the drawer; 
     
     
         10 . The vacuum preservation device of  claim 8 , wherein the rotating shaft rod of the drawer body sealing assembly includes a shaft rod, shaft rod discs, and cams each having a first side edge and a second side edge. 
     
     
         11 . The vacuum preservation device of  claim 10 , wherein the first side edge of each cam is perpendicular to each of the shaft rod discs. 
     
     
         12 . The vacuum preservation device of  claim 10 , wherein the second side edge of each cam extends obliquely downward from a top of each cam to one of the shaft rod discs. 
     
     
         13 . The vacuum preservation device of  claim 8 , wherein the second fixing fastener includes:
 a pin fixing fastener including a support column fixing fastener; and   connector plates operably coupled to a first end of each of the pin fixing fastener and the support column fixing fastener and operably coupled to a second end of each of the pin fixing fastener and the support column fixing fastener.   
     
     
         14 . A vacuum preservation device, comprising:
 a drawer including a drawer panel that defines a mounting slot;   a door body sealing assembly including a rotating shaft rod;   a handle operably coupled to the door body sealing assembly;   a preservation container body including:
 a sliding part defining an opening; and 
 a fixing part selectively disposed within the opening defined by the sliding part. 
   
     
     
         15 . The vacuum preservation device of  claim 14 , wherein the door body sealing assembly includes ejector rods, and wherein the ejector rods each include a support plate and a pin operably coupled to the support plate.
