         3 . The powder box of  claim 2 , wherein the first side of the box cover is provided with an L-shaped buckle; the L-shaped buckle is elastic and butts against the first outer side wall of the hollow cylindrical base. 
     
     
         4 . The powder box of  claim 1 , wherein the box cover comprises a mirror facing the upper opening of the accommodation cavity. 
     
     
         5 . The powder box of  claim 2 , wherein:
 the middle sleeve comprises a first middle sleeve and a second middle sleeve;   the first middle sleeve comprises a first body in the shape of a circular plate;   an edge of the first body extends away from the opening of the inner disc to form an extension unit, and an outer side wall of the extension unit extends radially outwards to form a connection unit;   the second middle sleeve comprises a second body which is a hollow cylinder comprising upper and lower openings;   an outer wall of the second body extends radially outwards and bends downwards to form a folding part;   an inner wall of the second body extends radially inwards to form a support part;   one side of the connection unit is hinged to and integrated with one side of the folding part;   the first body is flexibly disposed on the second body to open or seal the upper opening of the second body; and   the inner disc comprises a hollow cylindrical body which comprises an upper opening and an outer side wall, the outer side wall of the hollow cylindrical body is provided with male threads, and the inner wall of the second body is provided with female threads corresponding to the male threads.   
     
     
         6 . The powder box of  claim 5 , wherein:
 taking a state that the first body seals the upper opening of the second body as a reference, an outer side wall of the extension unit extends towards the support part to form two coaxial first airtight strips, a side wall of the support part protrudes towards the extension unit to form a second airtight strip;   the second airtight strip is located between the two coaxial first airtight strips;   one of the two coaxial first airtight strips is attached to the second airtight strip, and the other coaxial first airtight strip  2013  is attached to the inner wall of the second body; and   the inner wall of the second body is provided with a plurality of airtight ribs between the support part and the female threads.   
     
     
         7 . The powder box of  claim 5 , wherein an inner side wall of the hollow cylindrical base comprises a depression; an outer side wall of the folding part protrudes radially outwards towards the hollow cylindrical base to form two convex hulls disposed up-and-down; a radial width of a lower one of the two convex hulls is less than that of an upper one of the two convex hulls; the lower one of the two convex hulls is inserted in the depression of the hollow cylindrical base, and the upper one of the two convex hulls is supported by an upper surface of the hollow cylindrical base. 
     
     
         8 . The powder box of  claim 5 , wherein an outer bottom wall of the hollow cylindrical body is sunken to form a containing groove.
