ABSTRACT:
The present invention relates to a operating device for a telescopic handle of a luggage cart. The handle includes a transverse bar defining an internal chamber therein and an aperture on the right top end, a pair of telescopic tubes with their top ends respectively fixed to opposite ends of the transverse bar. A pair of linkages are respectively and movably received in the internal chamber. Each one of the linkages moves in reversed orientation, such that a pivotal movement is initiated to cause an upward and a downward movement simultaneously while the operating device is activated. The movement of the operating device in reversed orientation will accomplish the extending or folding of the tubes.
