A retractable handle assembly includes a shank 10, an extension pipe 20, a retractable pipe 60, a receiving member 70, an expandable member 80, a control member 50, a driving member 40, and a rotation member 30. The retractable pipe 60 is movable relative to the extension pipe 20 by rotation of the rotation member 30 to adjust the distance between the retractable pipe 60 and the extension pipe 20 so as to adjust the length of the retractable handle assembly. The assembly is locked by rotating the control member 50, which passes through the expandable member 80, so that the expandable member 80 is pressed outwardly to press the extension pipe 20 and lock the retractable pipe 60 onto the extension pipe 20. Preferably, the control member 50 has a pair of push flanges 50, each of which is inserted into a respective locking recess 85 of the expandable member 80 by rotation of the control member 50. The control member 50 is therefore locked by the expandable member 80, thereby preventing the control member 50 from being jammed due to an excessive rotation. |
