Abstract:
1. A retention assembly, comprising: a platform comprising a frame having a top surface and a mounting surface substantially perpendicular to the top surface, and a connecting portion formed on the top surface of the frame, the connecting portion comprising two side boards formed at opposite sides thereof; a bracket comprising a main portion and a fastening portion extending substantially perpendicular from an end of the main portion, the bracket mounted on the frame of the platform, with the main portion and the fastening portion of the bracket respectively abutting on the corresponding mounting surface and the top surface of the frame; two pivot shafts; two torsion springs; and a resisting member rotatably connected to the connecting portion of the platform via the two pivot shafts, and elastically resisting against the bracket via the two torsion springs, for fastening the bracket to the platform; the resisting member comprising a resisting portion, an elastic catching tab bending from the resisting portion and two connecting arms formed at opposite ends of the resisting portion, the elastic catching tab comprising a joining portion and a catching portion; wherein the two connecting arms rotatably connected to the two side boards via the two pivot shafts, each of the two torsion springs comprises two ends respectively connected to one of the two connecting arms and one of the two side boards and exerts an elastic force impelling the resisting member to rotate towards the platform, such that, the resisting portion tightly resists the fastening portion; the elastic catching tab firmly catches the main portion; a second angle defined by the joining portion and the catching portion is less than a first angle defined by the main portion and the fastening portion.
