Abstract
A three-segmented expandable pull rod for luggage is composed of a handle, two first segments fastened with both ends of the handle, two second segments for receiving extractably and retractably the first segments, two third segments for receiving extractably and retractably the second segments, and two locating sets each having a control member, a main elastic element, a first retaining member and a second retaining member. The second segment is retracted into the third segment such that the bottom end of the second segment presses against the control member so as to cause the second retaining member to retract, thereby causing the first retaining member to engage the first retaining hole of the third segment. The second segment is extracted from the third segment such that the control member is urged by the main elastic element so as to force the first retaining member to retract, thereby causing the second retaining member to engage the second retaining hole of the third segment.
