Description of the invention (1) [Scope of the invention] The present invention is a vehicle crank that can be quickly folded. Volume: Background of the invention] Pressing, self-cultivation, sports, and people's attention. The volume structure of modern cars has been developed. Folding its maneuverability and multiplicity, each fold makes the entire bicycle effect, with convenient pedals. As the inner plate is bent up to eighty degrees, the nine pedals are erected on the curved product to reduce the width. But it is not perfect. The structure is often used in and related to a foldable crank, especially a foldable crank that provides self-folding and convenience, and can make full use of space to achieve the smallest driving. The car is an appliance, so it is. For the folding handle that has been folded by the suitable knot, the carrying handle and self-bending, the latter on both sides of the ten-degree vertical handle will not be able to be filled, and the operation of the seed transmission, especially the driving with the shrinking structure, The combination of the structure and the loading vehicle will divide the pedals into current or inconvenient alternatives to modern living products that have unique homes or small homes, and most of them will be used for load reduction due to the folding structure design; As the frame is folded or down, the side is straightened to the auxiliary position of the crank with the bicycle tool, and the tool, the quality of the sport is improved, and the important car can be carried on its own, and it must be sufficiently small, and It belongs to the bicycle that is ten degrees away from the hard crank and it is related to the bicycle under the width handle, or it is still a modern one. The convenience of sports, sex and leisure is to use the space to match the folding of the car to achieve the best bicycle. The structural design is straight, but, it is not easy to fold, although it does not take time to fold the pedals between the frames and revise it. , Mention self bicycle parts like phase, before the folded side projections as the former one hundred lines the depression of the body to increase the stack space side, of the crank, cumbersome good, projection

Description of the invention (4) Screwing; and the handle connecting hole 2 6 of the pedal handle 2 and the lever 3 6 are respectively inserted into the first connecting hole 2 of the curve 2 and the second lever 3 5 protrudes. After the crank is set, the process is completed. Please refer to the section “To move the pivot body at this time, the first pivot rod to the slot 1 3 of the pivot rod 3 7 is screwed to the relative movement of the rod 3 7 to drag the rod 3 7 For axis advancement, release the elastic action of the pivot button body. The re-entry joint hole 2 3 has been rotated to become the third joint hole 2 4 (as in the rear folded position. The space between the frames is the second pivot lever 3 6 bis pivot. The push of the post 3 6 and the reset of the third hole 2 4 can be inserted. The 4 series is provided with a pedal connection ^ Wax pole connection 4 1 is used to connect to the first and the third joint of the button 3 Post 35, one of the second pivot handles 苐-pivot hole 14, * second second pivot hole 15 and adapter 2 brother one connection hole 2 3 'and then use the nut 3 9 to connect the first pivot 1 to the other side The combination of the pivot screw end 3 7 2 of the pivot lever 3 7 and the folding crank of the bicycle fixed with a screw lock. Figures 4 and 5 show that when the pedal 4 of the present invention is to be folded 3 1, it is pulled out to one side of the crank 1 (As shown in the fourth picture), 3 5 and both sides The second pivot link 36 will release the pivot brake of the docking handle 2 outside the space of the pivot body 3 i, and because the nut 39 does not move, the first pivot link 35 and the pivot pair spring 38 compress and store energy. At this time, the shank 2 can be rotated ninety degrees to turn the locust. When the shank 2 is rotated to the position of 3 1 when it is positioned, the first pivot post 3 5 is connected to the shank 2 by the spring 3 8 Hole 2 2 'and because of the second position of the handle 2, the second pivot rod 36 of one of the pivot buttons 3 will enter the sixth figure), that is, the handle 2 is locked again when the pedal is rotated. 4 is folded to the inside of the crank 1 and it is placed with the bicycle. The first pivot post 3 5 is inserted into the first connection hole 2 2 and the third connection hole 2 4, because the first connection post 3 5, the second extraction end 3 5 4, 3 6 4, and the first connection hole 2 2. The second connecting hole 2 3 pushes the extended end 2 2 1, 2, 3 1, 2, 4 1 to make it go smoothly. Furthermore, because of the length of the first pivot rod 3 5
