A coupling plate frame is integrally made of hardened high molecular material and comprises a top plate section a vertical plate section, a bottom plate section, and two flap plates. The top plate section has an engaging hole thereon. The vertical plate section is integrally associated with the top plate with a width gradually reduced from a top to a bottom thereof, and has an engaging hole near the bottom thereof. The bottom plate section is attached integrally to the vertical plate section with extending outward and opposite to the top plate section from the vertical section plate. Each of the flap plates is integrally attached to the top plate section, the vertical plate section, and the bottom plate section, respectively. Each flap plate is slant at the top plate section and extends downward along the vertical plate, and the width between the flap plates is gradually smaller from a top thereof to a bottom thereof. Two of the coupling plates can be lapped to each other without occupying extra space.

1. A coupling plate frame integrally made of hardened high molecular material, comprising: a first plate section with an engaging hole; a second plate section, spaced from the first plate section; a vertical plate section formed integral with, and connecting the first and second plate sections, the vertical plate section having a width diminishing in a direction from the first plate section toward the second plate section, the vertical plate section having an engaging hole near the second plate and a first face with an elongated central recess extending from the first plate section to the second plate section and a second, opposite face with a rib corresponding in location to the elongated recess; and a flap plate extending from each of two opposite lateral sides of the first plate section, the vertical plate section, and the second plate section, respectively, a distance between the flap plates being greater than a width of the second plate section; whereby, the coupling plate can be lapped to another coupling plate. 2. The coupling frame according to claim 1, further comprising an arcuate connection at each of an intersection of the first plate section and the vertical plate section, and an intersection of vertical plate section and the second plate section.
