Folding handlebar mechanism and folding vehicle having same

摘要

A folding handlebar mechanism (1;1a) includes a steering tube (10), a stem assembly (20;20a) mounted on the steering tube (10), two handlebars (30) rotatably and slidably mounted into two distal ends of the stem assembly (20;20a), a repressed member (40;40a) abutted against the stem assembly (20;20a), and a positioning assembly (50;50a). The positioning assembly (50;50a) is operable between a tighten mode and a loose mode to cause the two handlebars (30) selectively rotatable and slidable with respect to the two opposite ends of the stem assembly (20;20a).
