Abstract

A suitcase has a retractable handle assembly. The retractable handle assembly has a grip, a positioning seat, a base seat, two inner pipes, two outer pipes, two collars, two positioning mounts, two blocks, and two torsion springs. The base seat is disposed in a bottom of the suitcase. The positioning seat is disposed on a top portion of the suitcase. The grip has two distal sockets receiving the inner pipes. The positioning seat has two lower sleeves receiving the collars and the outer pipes. The base seat has two tubes receiving the outer pipes. The positioning mounts are inserted in the outer pipes. The blocks and the torsion springs are inserted in the inner pipes. The inner pipes are inserted through the lower sleeves, the collars and the positioning mounts and inserted in the outer pipes.
