Patent ID: 8808051

Claim:
In a coupling structure having a main board and at least one coupler detachably connected to the main board, wherein the structure comprises: the main board having at least one coupling trough defined therein, a first abutting element defined in a side face of the at least one coupling trough and a support beam formed adjacent to the at least one coupling trough; the at least one coupler having at least one first arm and at least one second arm extending in a direction different from that of the at least one first arm so as to receivably contain therebetween the support beam, the at least one first arm having a second abutting element formed at a distal end of the at least one first arm to correspond to and abut a periphery of the first abutting element so that engagement between the main board and the at least one coupler is detachably secured; and the at least one first arm and the at least one second arm being located separately from one another and maintaining an open receiving space between the at least one first arm and the at least one second arm to receive therein the support beam during attachment, and to release therefrom the support beam during detachment.
