A retractable luggage carrying handle positioning device comprising: an upper mounting frame transversely fastened to a luggage at an upper elevation and having two first tubular mounting blocks; a lower mounting frame transversely fastened to said luggage at a lower elevation and having two second tubular mounting blocks; two parallel outer tubes having a respective top end fastened to a first tubular mounting block of said upper mounting frame and a respective bottom end fastened to a second tubular mounting block of said lower mounting frame; a hand grip having two opposite ends; two inner tubes each having a respective bottom end inserted through a first tubular mounting block of said upper mounting frame into an outer tube and a respective top end connected to one end of said hand grip; a tubular end member extending into the top end of each outer tube so as to permit the top end of the respective inner tube to pass therethrough; a tubular stop fastened onto the bottom end of each inner tube which stops against the tubular end member on the top end of the respective outer tube to limit the stroke of the respective inner tube relative to the outer tube, the tubular stop having an outer surface; two inward projections extending inwardly on each outer tube at different elevations, which permit the respective inner tube to slide in the respective outer tube and which engage the outer surface of the tubular stop member of the respective inner tube; two locking devices to lock said inner tubes at a desired length as said inner tubes are pulled out of said outer tubes by said hand grip, each locking device comprising: (i) two parallel lugs respectively and horizontally extending outwards from a first tubular mounting block of said upper mounting frame; (ii) aligned holes defined by the first tubular mounting blocks and the top ends of the outer tubes located between the two parallel lugs; (iii) a friction block received in the aligned holes on a first tubular mounting block of said upper mounting frame, said friction block having a smooth inner wall in contact with an inner tube and a curved, toothed outer wall disposed outside the respective tubular mounting block; (iv) a pivot mounted between said parallel lugs; and (v) a lever having a tubular rod portion pivoted about said pivot and an end terminating in a finger rod, said tubular rod portion of said lever having a series of teeth around a portion of a periphery thereof, the teeth on said tubular rod portion of said lever engaged with the toothed portion of said friction block causing said friction block to tightly stop against the respective inner tube to hold it in position as said lever is turned in one direction, the teeth on said tubular rod portion of said lever being disengaged from the toothed portion of said friction block causing said friction block to release the respective inner tube as said lever is turned in the reverse direction.
