A multidirectional aluminum extrusion connection device includes a direction-change coupling member having two ends respectively forming first and second coupling sections arranged in an angularly-staggered manner to extend in different directions for each connectable with a connection member. A first aluminum extrusion plate is provided to receive one of the connection members to extend therethrough so as to be set at a location corresponding to the first coupling section. A second aluminum extrusion plate is provided to receive the other one of the connection members to extend therethrough so as to be set at a location corresponding to the second coupling section. The first and second aluminum extrusion plates are thus connected in an angularly staggered manner to form a connection module having and defining a corner. The connection members may be additionally connected two pre-prepared aluminum extrusion parts for respectively coupling to the first and second aluminum extrusion plats.
