Claim Text:
1. A combination backboard, comprising: a main body and a first bracket coupled to the main body, the main body comprising a base plate and first and second side plates perpendicularly mounted to the base plate, the first and second side plates being arranged opposite to each other, the first and second side plates each having an end adjacent to the first bracket and forming a first coupling section, the first bracket comprising a first bottom plate and a third side plate perpendicularly mounted to the first bottom plate, the third side plate having two ends respectively forming first coupling slots corresponding to the first coupling sections, the first coupling sections being respectively received and retained in the first coupling slots to couple the first bracket and the main body together in such a way that a surface of the base plate is substantially flush with a surface of the first bottom plate to collectively define a flat planar surface; wherein the first coupling sections are of an L-shape and are of resiliency, which is substantially coplanar with and horizontally extends in a direction along the first or the second side plate beyond the base plate, and each of the first coupling sections has a distal free end that is curved and defines an edge extending vertically so that the edges of the free ends of the first coupling sections face each other and wherein the first coupling slots are formed in the two ends of the third side plate to face away from each other and extend vertically through the ends of the third side plate and are perpendicular to the flat planar surface and the surfaces of the base plate and the first bottom plate thereby each defining an upper opening and a lower opening in top and bottom sides of the third side plate for receiving the edge of the distal end of the corresponding first coupling section to slidably insert into the first coupling slot from the upper opening in such a way that the edges of the free ends of the first coupling sections are simultaneously received into the first coupling slots to securely and stably retain the third side plate in position through the resiliency thereof.
