Switch between wheels to achieve the purpose of shifting. With regard to the conventional shift chain design, most of the emphasis is on the cooperation with the sprocket, so that the chain can easily enter the gear during the shifting process, and can avoid the interference problem when the gear shifts. In order to make the chain at the speed of exchange, the sprocket can be easily put into the gear. The inventors have designed a cut-in portion for the inner surface of the middle portion of each of the two opposite outer chain plates in the chain, so that the two are in the same position with respect to the outer chain plate. The space expands its space by the design of the concave cut-in portion, so that when the chain is changed between the sprocket, the sprocket can be accessed through the cut-in portion, thereby providing an easy-to-upgrade Shift chain. However, the above-mentioned shifting chain is designed to be easy to be lifted by the improved design of the outer chain plate, but since it is only for the improvement of the outer chain plate, the entire chain is & The inter-board space is provided between the two sides of the board. The shifting space is also formed between the two inner chain plates. Therefore, when the shifting chain is in the switching position, if the remaining part of the sprocket tooth portion falls in the opposite inner chain entry space The entry space between the two inner chain plates is smaller than that between the two 4 M338930 key plates, and the two rooms are narrower. Even if the outer chain plate has an easy upper I#, it is not enough to enter the government.穷 穷 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上 上Shift chain. The type can be easier [new content] The main purpose of this creation is to provide a "shift type key bar for the shift key bar to be applied to the bicycle shifting transmission mechanism, so that ===:" can reduce the interference during shifting in all directions. The easy-to-use, up-shifting and smoothing of the shifting. The shifting chain designed to achieve the previous project I included the fi:, and the chain as early as the ring body formed by the chain pin, The chain unit has two opposite inner chain plates and two opposite outer chain plates, and the two inner side plate end ends are combined with a key roller and a chain pin to connect the two opposite outer chain plates. At the side ends, the two opposite outer/inner link plates respectively form a circular arc end portion having a pin hole and an intermediate portion between the two arc end portions, and the inner surface of the middle portion forms a concave-shaped obliquely cut portion And the two opposite outer/inner plates are inclined obliquely in opposite directions from the opposite side of the inner surface of the inner chain plate. Arc end. With this design, the design of each shifting chain is opposite to the outer chain plate. The oblique cut-in section expands the entry space, and further enables the entry space between each of the two opposite inner link plates to be designed by the oblique cut-in portion of the inner face, and the entry space between the two inner link plates is made. Appropriately increase the space and eliminate the edge that interferes with the sprocket. Thus, the shifting chain is switched between the sprocket wheels at 5. M338930, regardless of the sprocket's in-position position. The entry space between the two, or the entry space between the two opposite inner chain plates, can be designed by the comparison of the lower entry space and the larger opening space, so that any part of the entire chain can be chained. The cutting of the gear teeth reduces the obstacle of entering the gear, so that the shifting chain can fully exert its function of smooth shifting and is only easy to go up.

By using the guide bevel design of the inner and outer link plates, the edge which interferes with the gear tooth insertion is eliminated, and the opening between the entrances is enlarged, so that the shift chain is switched between the sprockets. Position, regardless of the entry position of the sprocket, the entry space between the two opposite inner key plates, or the entrance space between the two opposite inner link plates, can be opened by the opening space and the inclined surface The priming function allows any part of the entire chain to make the sprocket tooth easier to cut in, reducing the obstacles of entering the file.
