An improvement of the pop-up mechanism for an extendable handle of wheeled luggage is disclosed. The popup mechanism comprises an additional elastic device in the overlaying section of the sliding tube and the support tube for cooperating with a first elastic device and a fastening device. Once the push button is pressed by a hand the sliding tube locked by the pin of the push button is unlocked and thus the sliding tube moves downward a predetermined distance. In this manner, the hand pressing the push button previously will be able to leave the push button unattended. Then use the same hand to push down the sliding tube to its lowest locked position. As a result, the purpose of retracting the handle by a single hand is fulfilled.
