ABSTRACT:
A retractable handle control mechanism including a movable control block mounted in a longitudinal hole on the transverse handgrip of the retractable handle and moved by a control knob, two beveled edged links connected between the beveled guide blocks of two release control rods, which are moved in the inner tubes, and the two opposite bevel edges of the movable control block, and return control spring means, whereby when the control knob is depressed to lower the movable control block, the links are moved outwards in reversed directions to force the bevel guide blocks of the release control rods downwards, causing the release control rods to release the respective latches from the sleeves for permitting the inner tubes to be moved by the transverse handgrip between the retracted position and the extended position.
