A retracting handle bar including a plurality of tubes that slide one inside another, a plurality of lock devices for locking the tubes in the extended position, and a press bar for unlocking the lock devices, wherein: each of the lock devices includes an axial member mounted in one end of an antecedent tube, a retainer strip pivoted to the axial member, and a socket mounted around the retainer strip and the axial member, the axial member having a body with a taper hole at one end, and an extension rod at an opposite end, the body of the axial member being inserted into a second tube, the axial extension rod of the axial member being inserted into the antecedent tube, the retainer strip having a fixed end pivoted to the axial extension rod of the axial member inside the antecedent tube, and a free end disposed inside the antecedent tube, the free end of the retainer rod having a raised portion forced into engagement with a locating hole in the antecedent tube, the socket being disposed inside the second tube, having an inner diameter smaller than the outer diameter of the body of the axial member, and at least one axial spring arm, each of the at least one axial spring arm having a raised portion at an outer side forced into engagement with one locating hole in the second tube; when the press bar is depressed, the retainer strip of each lock devices is disengaged from the corresponding tube, permitting the retracting handle bar to be collapsed.

[ What the invention claimed is:] [1.] A retracting handle bar comprising a plurality of tubes that slide one inside another, a press bar mounted in one of said tubes and controlled to release said tubes for permitting them to be collapsed and received inside one another, a plurality of lock means respectively mounted in said tubes for locking said tubes in an extended position, wherein:each of said lock means comprises an axial member mounted in one end of a first of said tubes, a retainer strip pivoted to said axial member, and a socket mounted in a second of said tubes, said axial member comprising a body having a taper hole at one end and an axial extension rod at an opposite end, the body of said axial member being inserted into the second tube, the axial extension rod of said axial member being inserted into the first tube, said retainer strip having a fixed end pivoted to the axial extension rod of said axial member inside the first tube, and a free end disposed inside the first tube, the free end of said retainer strip having a raised portion forced into engagement with a locating hole in the first tube, said socket being disposed inside an second tube, having an inner diameter smaller than an outer diameter of the body of said axial member, and at least one axial spring arm, each of said at least one axial spring arm having a raised portion at an outer side forced into engagement with one locating hole in the second tube; when said press bar is depressed, said retainer strip is forced by said press bar to release the raised portion from the first tube for permitting the first tube to be inserted into the second tube, so that the taper hole of the body of the axial member which is connected to the first tube is forced against the retainer strip of the lock means in the second tube, causing the raised portion of the retainer strip of the lock means in the second tube to be disengaged from the second tube, permitting the second tube to be received inside a third of said tubes.
