Multidirectional aluminum extrusion connection device

A multidirectional aluminum extrusion connection device applicable to connection with at least two fourth aluminum extrusion plates, wherein the fourth aluminum extrusion plates are each formed with a third fitting slot, the aluminum extrusion connection device comprising:

• two connection members, wherein each of the connection members is formed with a first open groove in one end thereof and a second open groove in another end thereof, the first open groove being pivotally connected with a bar to allow the bar to be movable up and down in the first open groove, an opposite end of the bar extending outside the first open groove and pivotally connected with a pressing stem, the connection members being provided on each of two opposite sides thereof with a compression block;
• a direction-change coupling member, which is connectable with the two connection members, the direction-change coupling member being provided with a first coupling section at one end thereof and a second coupling section at the other end thereof, the first coupling section and the second coupling section being arranged to extend in different directions so that the first coupling section and the second coupling section define therebetween an angle, the first coupling section being connectable to the second open groove of one of the connection members, the second coupling section being connectable to the second open groove of the other one of the connection members;
• a first aluminum extrusion plate, which is connectable with one of the connection members, the first aluminum extrusion plate being formed with a first fitting slot, said one of the connection members and the first coupling section of the direction-change coupling member being received into and set in the first fitting slot to set the first aluminum extrusion plate at a location corresponding to the first coupling section and the connection member received through the first fitting slot to project outside the first aluminum extrusion plate;
• and
• a second aluminum extrusion plate, which is connectable with the other one of the connection members, the second aluminum extrusion plate being formed with a second fitting slot, said the other one of the connection members and the second coupling section of the direction-change coupling member being received into and set in the second fitting slot to set the second aluminum extrusion plate at a location corresponding to the second coupling section and connection member through the second fitting slot to project outside the second aluminum extrusion plate.
