A hinge assembly includes a fixing seat, a position seat having a first annular body and a second annular body opposite to the first annular body, a fixing ring securely engaged with the first annular body and having a pair of notches and a position ring having a pair of protrusions extending out to correspond to the pair of notches. A connection rod is provided to securely sandwich the fixing ring, the position ring and the multiple resilient pads between the first annular body and the second annular body so as to securely engage with a securing device. Pivotal movement of the position seat relative to the fixing seat drives the position ring to pivot such that the protrusions are alternatively received in the corresponding notches and thus the multiple resilient pads are able to provide necessary friction when the protrusions are away from the notches.
