Abstract: The present invention provides an engagement assembly for connecting a reflector and a connecting rod. The engagement assembly has a fixing base and a fixing plate. The fixing base has a head accommodating room for holding a head portion of the connecting rod and a plate retaining space formed between two protrusion rings. The fixing plate is mounted in the plate retaining space and has a position-limiting portion and two fixing portions. The position-limiting portion has a through hole for inserting the head portion and at least two tongues. The tongues are mounted on an inner edge of the through hole for clamping the head portion of the connecting rod that has entered the head accommodating room. The engagement assembly provides a strong linking structure for the reflector and the connecting rod.
