Abstract:
An adjusting and positioning structure for handle bars of trunks and the like, comprising a securing tube assembly that is hollow and secured on one side of a trunk; a handle bar that is provided pivotally and axially in said securing tube assembly in a slidable manner; and a positioning component that is capable of positioning said handle bar in said securing tube assembly, whereinsaid positioning component includes at least one positioning pin that is subjected to the urging action of an elastic element to displace axially, said positioning pin being disposed in a radial parallel position of said handle bar, a control pin that is likewise subjected to the urging action of an elastic element being disposed below said positioning pin in a parallel position, one side of said control pin having a limiting portion capable of controlling axial displacement of said positioning pin, said securing tube assembly being radially provided with a plurality of axially spaced positioning portions corresponding respectively to said positioning pin and said control pin for receiving said positioning pin and said control pin inserted therein, the positioning portion corresponding to said control pin further extending downwardly to a certain axial distance to form an urging end at a bottom end thereof to urge against and control the axial displacement of said control pin when the latter displaces downwardly, whereby said handle bar can be pressed downwardly very quickly and then pulled axially upwardly very quickly to achieve adjustment and positioning of said handle bar.
