New description: [New technical field] This creation is related to the bicycle shifting structure. In detail, it is a bicycle shifting structure that is convenient for the rider to get the speed change and return to the bicycle when riding the bicycle. [Previous technology] According to the bicycle, the bicycle has the characteristics of being able to travel far and the environment is environmentally friendly, and in the day when it is focused on the rest of the life, it is engaged in the leisure of _ _ experience the comfort of nature, the most suitable for the smooth and healthy p疋 ride Since the car is smashed, the bicycle is mailed but the chain is Wei, and it can also be cultivated. It is the most suitable sport for modern people. And in the case of two days off, people have increased their leisure time, so they are raised in the health level. Under the circumstances, the design of bicycles has been paid more attention. Please refer to the Zhonghuaguan Specialist Lai Xian (4) Bing No. 6 "Bicycle Change Operation Pack", "The System Mounted on - Bicycle Handle" contains at least: "Domain member, which is a stepped body with a plate and Extending upwardly, a core pumping 'the bottom end of the disc portion is assembled on the bicycle handle'--winding member, the frame is arranged on the support member spindle, and the steel shackle can be tightened or loosened; a card 'system core 3 has 0 The splicing member is fixed by a fixing plate to restrict the winding member from being held by a special (10) plucking plucking mechanism. The mechanism is disengaged from the winding member, and the winding member 1 is freely rotated to relax the palm line. The upper gear lever structure of the support member spindle is provided with an upper lever, and is disposed on the central axis of the supporting member; a transmission arm having a member fixed to the upper shift lever member for displacing the upper shift lever member to drive the transmission mechanism, and for pushing the wire member to tighten the cable, or The winding member freely rotates and loosens the steel tree to temporarily stop the winding member; by means of the lower jaw member, the card Machine 3 M412129 :=:Γ机_连_使—松峨钢(四) The above-mentioned creation system is a bicycle shift control operation of the model, which is used to control the winding member to tighten or loosen the cable to achieve dry shifting. The lever of the control device is usually set to the driver's lever. When the handlebar is to be changed, the handle must be removed. The upper and lower passengers are used to make the rider adjust and read, and (4) the safety is transmitted. _. The above-mentioned shortcomings of the "Essence of the 7th" is the creator's introduction. The bicycle shifting structure 4 series j driving handlebars are presented in a set-up setting, which is indeed available for the rider to ride the self-financing, set the hand to rotate the movable collar To change the tightness of the control line
