New description: [New technical field] This creation provides a technical field of bicycles, especially in terms of technically providing a bicycle folding structure. [Prior Art] According to 'according to the leisure time and the growth of falsehoods', more and more people like to use bicycles as a means of transportation and sports. However, because the range of activities of bicycles is still limited by the force of receptors and mobility, it is impossible to make long distances. The rapid movement 'Therefore, if the land is to go to the land first, then take the bicycle to travel to the land, then the train, the MRT, the car, etc. will usually be used to transport the bicycle from the land to the land. However, the size of the bicycle used is too big, so it is developed to use the folding bicycle. However, it is not difficult to find that it is for single-bar frames and smaller bicycles. Design, however, the small bicycle does not occupy space after folding, and because it is a small bicycle, it is less comfortable to ride, and the related folding and fixing structure is complicated and inconvenient to operate. In view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure with more ideal and practicality, the consumers are eagerly awaiting, and the relevant industry must strive to develop the goal and direction of breakthrough. In view of this, the creator is too embarrassed; in the eve of the year, he is engaged in the manufacturing development and design experience of related products. After the above-mentioned design and careful evaluation, 3 M373317 will have a practical and practical creation. [New content] The technical problem to be solved: the bicycle used in the past is too big, so it is developed to use the folding bicycle. However, it is not difficult to find that it is for the single-bar type. The frame and the smaller bicycle are designed. However, the small bicycle does not occupy space after folding, but because it is a small bicycle, it is less comfortable to ride, and (4) the folding fixed structure (4) is not convenient to operate. . Technical Problem for Solving the Problem: Providing a bicycle finger stack structure mainly uses the ring gear device to be repeatedly used on a bicycle structure, and the ring gear device uses the locking unit to move the movable tooth when the toothed teeth of the ring gear device are engaged with each other The ring pushes toward the fixed tooth _ to make it bite. When the bite is engaged, the locking unit is fixed to the seat tube to make the bite even, and the β is convenient. Not loose. When folding, after the locking unit fixed to the seat tube is loosened, the movable tooth ring is separated from the fixed tooth ring to separate it from the activity of rotating on the seat tube at the time of separation The tooth ring, # is rotated by the movable tooth ring to drive the direction of the pipe that is fixed to it, and can fold one of the front triangles of the first car to the rear triangle. Compared with the efficacy of the prior art: the creation of the frame is at least for the upper and lower tubes of the vehicle. Therefore, it can be applied to a larger bicycle, and the main tooth ring device is repeated only for the upper tube. The number of teeth of the ring gear device between the seat tube and the lower tube and the seat tube or between the upper tube and the upper tube of the five-way tube and between the lower tube and the lower tube of the five-way tube When meshing with each other, the M373317^tooth ring device pushes the movable tooth ring toward the fixed tooth circle by the locking unit to make it bite, and fixes the locking unit to the seat tube at the time of the bite, so that the bite is not engaged Loose. When folding, the locking unit fixed to the seat tube is loosened, and the movable tooth ring is separated from the fixed tooth ring to be separated, and the sleeve is rotated on the seat tube when the knife is separated The movable tooth ring can drive the rotation direction of the pipe member fixed thereto by the rotation of the movable tooth ring.
