When the top end of the guide pin 313 moves into each section of the guiding groove 234, the bottom end of each guiding pin 313 is also moved into the opposite section of each of the opposing guiding grooves 235, and then the handle structure 30 is pulled outward to make the guiding pins The top end of the 313 is moved outward along the straight section 2342, and both ends of the guide pins 313 are moved to the guide grooves 234. And the outer ends of the opposite guiding grooves 235.
最後如圖2、圖5所示，當各導引銷313移動至各轉折凹口212處時，以各導引銷313為轉動中心，將把手構造30的把手桿31以及把手32向下折疊，此時把手桿31朝下並朝內移至轉折凹口212內成為垂落的形態，此時將垂落的把手桿31套入把手桿架60左、右各側的C形扣管63內定位，即可完成折疊把手構造30的操作，如此的構造能將兩把手構造30折疊成與前叉頂桿10並列的狀態，可大幅減少整體構造所佔的體積，並且藉由各導引溝234以及各相對導引溝235的曲折設計，能在快拆構造50不慎鬆脫時，避免把手構造30能直接被外拉而垂落的狀況發生，使運用本創作的折疊自行車能獲得更佳的折疊縮小體積的效果，並進一步具有使用上較為安全的功效。Finally, as shown in FIG. 2 and FIG. 5, when the guide pins 313 are moved to the respective folding recesses 212, the handle bars 31 and the handles 32 of the handle structure 30 are folded downward with the respective guide pins 313 as the center of rotation. At this time, the handle bar 31 is moved downward and moved inwardly into the turning recess 212 to be in a falling shape. At this time, the falling handle bar 31 is placed in the C-shaped buckle tube 63 on the left and right sides of the handlebar frame 60. The operation of folding the handle structure 30 can be completed. Such a configuration can fold the two handle structure 30 into a state of juxtaposition with the front fork ejector 10, which can greatly reduce the volume occupied by the overall structure, and by the guiding grooves 234 And the zigzag design of each of the opposite guiding grooves 235 can prevent the handle structure 30 from being pulled out and fall down when the quick-release structure 50 is inadvertently loosened, so that the folding bicycle using the creation can obtain better. The effect of folding down the volume is further enhanced by the use of a safer effect.
