Abstract
The invention discloses a speed-change handle, which is used for speed-change gear shifting of a bicycle, and is reeled on the speed-change cable seat of a ratchet tooth speed-change mechanism by utilizing a speed-change cable. When a bicyclist shifts a gear-forwarding shifting rod, a gear-reversing shifting rod and a single gear-reversing rod, the speed-change cable seat is capable of reeling orreleasing the speed-change cable to achieve the goal of forwarding multiple gears, reversing the multiple gears or only reversing one gear. The ratchet tooth speed-change mechanism is provided with the gear-forwarding shifting rod, the gear-reversing shifting rod and the single gear-reversing rod. One gear can be forwarded to the multiple gears when the gear-forwarding shifting rod is shifted; one gear can be reversed to the multiple gears when the gear-reversing shifting rod is shifted; and when the single gear-reversing rod is shifted, one gear can be reversed. Operationally, after the ratchet tooth speed-change mechanism is driven by the gear-forwarding shifting rod, the speed-change cable can be reeled clockwise by the speed-change cable seat, so that a chain on a flywheel is forwarded to the multiple gears from one gear to realize rapid gear forwarding; if the gears are forwarded excessively, the gear-reversing shifting rod can be shifted to complete rapid gear reversing, and thesingle gear-reversing rod can also be shifted to only reverse one gear. The speed-change handle disclosed by the invention has the functions of rapidly forwarding and reversing the gears and reversing one gear at a time.
