A retractable handle of wheeled luggage is provided. For the case of single pulling rod, pressing a push button will tighten a connecting rod to move a lower sliding block to a one direction so that an upright rod is pressed to lower a locking member and an upright member to clear the locking member from a toothed member, thereby unlocking both the swivel handle grip and the pulling rod. For the case of two pulling rods, there is further provided another transmission mechanism so that pressing the push button will further unlock locking devices in the pulling rods via coupling rods.
