The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 5, this bicycle folder, the side of last folded formation 1 is provided with circular hole 21, and last folded formation 1 other end is provided with lock hook 5, and the gib head inboard of lock hook 5 is provided with an inclined-plane 5a.The side of following folded formation 2 is provided with slotted hole 7; Following folded formation 2 is provided with elongated insertion part 6, and elongated insertion part 6 is provided with inclined-plane 6a, and following folded formation 2 middle parts are provided with round end set screw 8; Following folded formation 2 hinge point are provided with a breach 22, and eccentric wheel handle 4 is arranged on by its eccentric cam part 9 on the jointed shaft 3 of this breach 22, and the eccentric cam part 9 of handle 4 contacts with the head of round end set screw 8.Jointed shaft 3 passes the circular hole 21 of folded formation 1, and the slotted hole 7 of following folded formation 2 and eccentric wheel handle 4 are hinged in the circular hole 21 of folded formation 1.
Turning handle 4, increasing along with the radius of curvature of eccentric cam part 9, the position changes between eccentric cam part 9 and the round end set screw 8, thereby promoting jointed shaft 3 radially slides in slotted hole, also promoting down simultaneously, folded formation 2 moves together, its elongated insertion part 6 is inserted in the lock hook 5, inclined-plane 6a and inclined-plane 5a closed contact, the fastener device is locked together.
