New description: • [New technical field] This creation department has a kind of "bike chain structure improvement". It is about a kind of chain that has both flexibility and structure, so that the bicycle is treading __ Lack of simplicity, and is not easy to fault, the chain is broken. [Prior Art] According to the bicycle, the bicycle has the characteristics of being able to travel far and environmentally, while in the leisure life today, it is engaged in leisure activities outdoors, experiencing the comfort of nature, and the most suitable and most healthy sports is cycling. The bicycle ride is not only a test of the chain, but also a good fit. It is the most suitable sport for modern people. ^In the case of the implementation of the two-day break, people have increased a lot of rest, so in the case of improved living standards, Various improved designs of bicycles have been paid more attention to; among them, the principle of the bicycle's operation is to connect the chain with the pedals of the pedals, thereby transmitting the power to the wheel body, thereby driving the bicycle forward; After the production technology of bicycles has matured, the functions attached to bicycles are more humanized. Many bicycles are equipped with shifting gears: can, _ gambler can make moderate adjustments in different riding needs, and if If the chain is smoother in shifting, the deflection of the chain is of considerable importance; the better deflection chain (4) can be compared to the slave Such a lion is changing speed, even when the user is stepping on it, but this will inevitably lead to a reduction in the structural degree; Ming tea reads the tenth _ to four figures, which is the customary chain body ( 9 〇), the key bar is composed of the chain pin (91) inserted into the chain view (92), and the outer chain plate (93) is sleeved by the chain pin (9 work). The chain body (94) is sleeved by the front and rear ends of the chain, and the chain body (9 〇) is formed by a structure of the chain (9 M289139. 7 The two-chain pin (9 i) and the chain roller (9 2) are in a state of full fit, the space of the curved space is limited, the deflection is small, and the chain body (9 Q) of the job is short and curved. This is more inconvenient in % multiplication and shifting; however, if the chain lock (9 work) and the outer chain plate (4 such as (92) and the inner chain plate (9 __ big' can improve the deflection, The strength of the structure of the junction body of each _ is reduced;
