Abstract: A signal receiving mechanism includes a cord reel, a cord wound around the cord reel, a signal receiving element assembled to a top of the cord reel, a grounding unit, and a pivot unit for rotatably connecting the cord reel to the grounding unit. The cord reel includes a hollow tubular body having a horizontal inner annular section. The cord includes a first and a second wire, inner ends of which are extended into the hollow tubular body below the inner annular section. The signal receiving element has a lower end downward extended through the inner annular section to electrically connect to the first wire of the cord. The grounding unit includes a first annular conductive plate, which is set at an underside of the inner annular section to electrically connect to the second wire of the cord, and is in contact with a conduction module for grounding.
