A secure screw locking structure for a telescoping drag link and fixing rod. When used in a luggage handle, it includes a pair of symmetrical drag links and fixing rods, a loop bar or insert and a setting seat or coupling, a screw block seat or hub and a control screw bush or knob located on each end of a transverse fixing seat or cross bar. The coupling has a setting hole or axial bore and a screw block seat or hub. The axial bore receives the outer end of the fixing rod; the fixing rod receives a hollow loop bar or insert having an integral leaf spring and bore and a limiting ring block or annular flange holding the insert in position in the coupling bore; and the insert receives the drag link. The control knob can be screwed into the thread hole of the hub and a locking block or retaining member forced by a screw block or tab of the knob when screwed in. Then the drag link can be held firmly in place by the spring pushed into engagement by a pin mounted in the knob. The control knob is retained firmly on the hub.
