The present invention discloses a overturning and folding device for handlebar, which comprises a tube (2) extending vertically from handlebar with an end (13), a connecting member (15) next to the end (13), an eccentric axle (1) and a lug bolt (12), a hole (21) in the axial direction and a hole (20) in the perpendicular direction are formed at the end (13) of said tube (2), they communicate with each other. The connecting member (15) is engaged to fork of bicycle. The connecting member (15) defines a space (14) through which the lug bolt (12) can rotate from axial position to perpendicular position. The lug bolt (12) is fixed within said hole (21) and space (14) by a fastener (8). The eccentric axle (1) is fitted rotatably in the hole (20) and hole (5) on head of lug bolt (12). A protrusion (3) on the end (13) is provided to match a recess (6) formed in corresponding position of said connecting member (15). A shim (18) hinged to the connecting member (15) and rotatable around said lug bolt (12) is provided between the connecting member (15) and the fastener (8). The device further comprises a torsion spring (17). One end of the torsion spring (17) is fixed to the connecting member (15) and the other end disposed on the shim (18). The eccentric axle (1) is connected to a lever (4). After the above-mentioned structure is adopted, the handlebar assembly can be folded and rotated to the direction in line with the main body. The folding can be done more conveniently and more timesavingly and the dimension after folding is decreased. <IMAGE> |
