Abstract

The invention discloses a speed change operation device, which comprises a casing, a coiling assembly, a shifting pawl, a stop ratchet, a positioning ratchet, a shifting lever for advancing and a shifting lever for retreating. The take-up assembly is pivotally mounted on the casing and is suitable for winding the bicycle cable. The forward gear pawl, the stop pawl and the positioning pawl are pivotally arranged on the housing and detachably engaged with the winding assembly. The advancing ratchet, the stop ratchet and the positioning ratchet are movable independently. The gear shift lever is pivotally connected to the housing. When the gear shift lever is activated, the gear shift lever drives the gear shift pawl to move and force the winding assembly to rotate in the first rotation direction. The reverse gear lever is arranged on the housing to move linearly. When the reverse gear lever is actuated, the reverse gear lever simultaneously drives the forward gear pawl, the stop pawl and the positioning pawl to move, so that the winding assembly moves in the opposite direction. Rotate in the second rotation direction of the first rotation direction.

Description

technical field [0001] The present invention relates to an operating device, in particular to a bicycle gear shifting operating device. Background technique [0002] In recent years, the sports atmosphere has gradually become popular, especially cycling, which has become one of the mainstreams of mass leisure activities. In order to increase the operability of riding, a general bicycle is often equipped with a transmission system with multiple chainrings and an operating device that controls the transmission system. The rider can operate the operating device according to the terrain or other needs to switch the chain to different positions. chainring to get the desired ride. [0003] The above-mentioned operating device is usually equipped with two levers, which allow the rider to perform the actions of shifting in and shifting out respectively. But traditionally, these two levers are rotary levers, and their positions are very close, which may easily confuse the rider and...
