The existing finger dial comprises a winding roll for winding a speed change line, wherein a ratchet is fixed on the winding roll and provided with two series of teeth, one tooth is used for being meshed with a push block arranged on a push rod (a general finger advance gear), the winding roll can be pushed to rotate by the push rod for winding, the other tooth is meshed with a pawl, the winding roll can be always kept at a certain fixed position, the pawl is controlled by a release rod, when the release rod pushes the pawl, the pawl is separated from the meshed teeth, and the ratchet retreats to the next tooth and then is meshed with the pawl. After the push gear is pushed, the conventional majority of finger-poked push rods need to ensure that the arranged push block is disengaged from the ratchet teeth, so that the normal retraction can be ensured when the release lever is operated to retract and release; therefore, in the existing finger-dialing, a protruding part is required to be arranged at the position, corresponding to the pushing block, on the fixing plate, and the protruding part is used for ejecting the reset pushing block out to be meshed with the ratchet after the gear shifting is finished; therefore, when the gear is shifted each time, the push block needs to move for a certain stroke to enable the push block to be separated from the protruding part of the fixed plate and meshed with the ratchet (equivalent to the distance of half of the ratchet), and then the ratchet wheel can be pushed to rotate for shifting; because the push block on the push rod can be engaged to shift the gear every time, the angle of the push rod pushed every time is increased, and the finger pushed by the push rod is easy to fatigue. Therefore, the existing bicycle speed changer controller has the problems that the gear is easy to be clamped in the gear shifting, the gear shifting pushing stroke is long, and the gear shifting operation is easy to be fatigued.
