Claim:
A retractable handle of a wheeled luggage, comprising: a pulling rod including one or more sliding tubes and a support tube; and a swivel handle grip mounted on a top of the pulling rod and comprising: an enclosed frame including a top recessed seat, a horizontal passage, and a bottom recess; and a transmission mechanism comprising: a push button slidably anchored in the top recessed seat, an upper sliding block disposed in the passage, a flexible connecting rod having one end fastened at the upper sliding block, a spring biased lower sliding block disposed in the bottom recess, a central sleeve extended downward from a bottom of the frame of the handle grip, the sleeve having an intermediate neck and a lower annular toothed member, an upright rod slidably received in a bore of the sleeve, a locking member engaged with toothed member of the central sleeve and a bottom of the upright rod, a spring biased upright member engaged with a bottom of the locking member, and a sheath interconnecting the sleeve and the upper sliding tube for enclosing the neck, the toothed member, the upright rod, the locking member, and the upright member; whereby pressing the push button will push one end of the connecting rod to move to a first direction and the lower sliding block to move to a second direction opposite to the first direction so that a top end of the upright rod is pressed by the lower sliding block to cause the upright rod, the locking member, and the upright member to move down to clear the locking member from the toothed member, thereby unlocking both the handle grip and the pulling rod.
