       8 . The apparatus, as recited in  claim 6 , further comprising a first securing member detachably attached to said inner wall of said boundary sleeve for biasing against said shaft of said outdoor umbrella, and a second securing member attached to said locking end of said locking member at said inner wall of said boundary cover, wherein when said locking member is rotated, said second securing member is driven by said locking member to adjust a size of said sliding through slot for fittingly biasing against said shaft of said outdoor umbrella. 
   
   
       9 . The apparatus, as recited in  claim 1 , wherein said electrical device comprises a plurality of illuminators suspendedly supported by said attaching device for providing illumination within said shadowing area of said outdoor umbrella. 
   
   
       10 . The apparatus, as recited in  claim 3 , wherein said electrical device comprises a plurality of illuminators suspendedly supported by said attaching device for providing illumination within said shadowing area of said outdoor umbrella. 
   
   
       11 . The apparatus, as recited in  claim 8 , wherein said electrical device comprises a plurality of illuminators suspendedly supported by said attaching device for providing illumination within said shadowing area of said outdoor umbrella. 
   
   
       12 . The apparatus, as recited in  claim 10 , wherein said attaching device further comprises a plurality of supporting arms outwardly and radially extended from said central hub, wherein said illuminators are suspendedly supported at distal ends of said supporting arms via ball joints respectively, such that each of said illuminators is capable of self-rotating while being suspendedly supported by said supporting arm in free-swinging manner. 
   
   
       13 . The apparatus, as recited in  claim 11 , wherein said attaching device further comprises a plurality of supporting arms outwardly and radially extended from said central hub, wherein said illuminators are suspendedly supported at distal ends of said supporting arms via ball joints respectively, such that each of said illuminators is capable of self-rotating while being suspendedly supported by said supporting arm in free-swinging manner. 
   
   
       14 . The apparatus, as recited in  claim 1 , wherein said attaching device comprises a shank body adapted for transversely extending through an awning arm as said elongated arm of said outdoor umbrella, and an adaptor connected to said shank body to suspendedly support said electrical device within said shadowing area of said outdoor umbrella. 
   
   
       15 . The apparatus, as recited in  claim 14 , wherein said attaching device further comprises a locking member detachably locking said electrical device at said adaptor to maintain said electrical device at a vertically down hanging manner regardless of said outdoor umbrella being folded between an unfolded position and a folded position. 
   
   
       15 . The apparatus, as recited in  claim 15 , wherein said shank body comprises an enlarged head adapted for mounting at an outer side of said awning arm and a connecting member protruding from an inner side of said awning arm, wherein a mounting slot is transversely provided at said connecting member for detachably coupling with said locking member so as to lock up said electrical device at said connecting member. 
   
   
       16 . The apparatus, as recited in  claim 15 , wherein said electrical device comprises an illuminator suspendedly supported at said connecting member of said shank body for providing illumination within said shadowing area of said outdoor umbrella.
