New description: [New technical field] The present invention relates to a folder structure for fixing two folding members in an extended state, in particular to ensure that two folding members are not arbitrarily folded and dispersed. The force of the hook plate and the trigger ensures the use of a secure folder structure. [Prior Art] As shown in the first figure (A), it is a conventional folding device structure commonly used in bicycles for fixing two folding members 91 of a bicycle in an extended state. The conventional folding device has two The first and second halves 92, 93 that are pivotally connected are respectively fixed to the two folding members 91 of the bicycle. The first half 92 is pivotally provided with a pull rod 95 and a trigger 96 on the other side corresponding to the pivot shaft 94. The trigger 96 is pivotally connected to the pull rod 95 through an eccentric shaft 97; The portion 93 is provided with a retaining groove 98 for the pull rod 95 to be inserted. When the plate handle 96 is pressed, the eccentric shaft 97 pushes the pull rod 95 axially, so that the pull rod 95 enters the retaining groove 98, and further The purpose of fixing the two folding members 91 of the bicycle in the extended state is achieved, and after the trigger 96 is released, the pulling rod 95 of the first half 92 can be pushed out of the locking groove 98 of the second half 93, so that the first 1. The second half 92, 93 is opened to allow the two folding members 91 of the bicycle to be folded together. However, in order to facilitate the extension and folding of the two folding members 91, the bicycle 96 is designed to be more easily pulled, so that if the bicycle system is stretched by two folding members 91, In the state, the probability of the trigger 96 being loosened by the external force is relatively high, and the lever 95 may exit the locking groove 98, causing the first and second halves 92, 93 to open, thereby preventing the bicycle from being opened. The two folding members 91 remain in an extended state, which seriously affects the safety of use. Therefore, the shortcomings of the conventional folding device are improved. As shown in the first figure (B), the conventional folding device has two first and second half portions 81 and 82 which are pivotally connected to each other for bicycles. The two folding members 91 are fixed to each other, and the other end of the first half 81 is provided with an eccentric shaft 83, and a hook plate 84 and a wrench 85 are pivotally mounted on the eccentric shaft 83, and the lever 85 is rotated. To release the fastening effect of the eccentric shaft 83 on the hook plate 84, as shown in the first figure (C), the knight can press the end of the hook plate 84 to cause the hook portion 86 to exit the block 87, so that the two bicycles The folding member 91 can be folded and folded relative to each other. In addition, the hooking plate 84 is provided with a magazine 88 at the bottom of the other end of the hook portion 86, and provides a topping action on the hooking plate 84, which normally causes the hook portion 86 to face the block. 87 position abuts, and when the hook portion 86 and the block 87 are engaged with each other and the trigger body 85 is pressed, the purpose of fixing the two folding members 91 of the bicycle in the extended state is achieved, and due to the spring 88 The topping action provides a safety mechanism to prevent the two folding members 91 from being loosened by the external force. Since the trigger body 85 and the hook plate 84 are both pivoted on the eccentric shaft 83, and the fine adjustment screw 89 for finely adjusting the position of the hook plate 84 also abuts against the eccentric shaft 83, the eccentric shaft 83 needs to simultaneously bear the knight 6 M348056 The force of the movable lever 85 against the pressing hook plate 84 and the fine adjustment screw 89, when the structural strength of the eccentric shaft 83 is insufficient, is likely to be broken, which seriously affects the safety of use. [New content] In view of this, the main purpose of this creation is to provide a way to ensure that the two folding parts are not arbitrarily folded, and that the hook plate and the trigger system are respectively disposed on the shaft and the crank rod, and the slatable plate can be dispersed. The force applied to the trigger ensures a safe folding structure. In order to achieve the above, the folder of the present invention has two first and second half portions which are pivotally connected to be respectively fixed to the two folding members, and the first and second halves are pivotally connected thereto. The movable end on the other side of the end is respectively provided with a hook plate and a trigger; wherein the trigger is connected to the second half through a crank rod which can rotate with the crank rod, and the crank rod has a hook plate phase The crankshaft that is held. The integral folder is fastened by the hook plate of the first half and the crank rod of the second half in a state where the movable ends of the first and second halves are closed, and the crankshaft is pressed at the trigger The tight rotation cooperates to gradually increase the degree of interference of the crank portion with the hook plate, so as to surely limit the opening of the first and second halves to achieve the purpose of fixing the two folding members in the extended state. And when the trigger is loosened, the crankshaft rod is rotated with the trigger to release the interference of the crankshaft on the hook plate. At this time, the operator must press the hook plate to lift the hook plate, so that the first and the first The second half of the smooth M348056 open? The two folding parts can be folded and folded relatively, and the 俾 can be up to eight W Μ帛帛—half part can be opened arbitrarily and because of the hook plate and the trigger system: it is not pivoted on the shaft rod and the crank rod, and the splicing plate can be dispersed. The force applied with the trigger 'and ensure the safety of the two folding parts. [Embodiment] The characteristics of (10) = can be clearly understood by referring to the detailed description of the drawings and the examples. As shown in the fourth figure, the folder structure of the present invention is used for folding and folding of a bicycle riser or a bicycle frame, and has two first and second half portions 10 and 20 for pivoting. Separately connected to the two folding members 1 respectively, wherein: the armature is on a movable end U corresponding to the other side of the light vehicle, and the hook plate 40 is transmitted through the first half of the shaft. The part 10 is pivotally connected, and the tail end of the hook plate 4 is provided with a hook portion ^, 3: the ί portion 1 corresponding to the hook portion 41 of the hook plate 4, and the other end position has a spring 12 for the normal state The hook plate 4 produces a force that causes the weeping to abut against the inside of the folder. The second half 2G is pivotally provided with a trigger 5〇 on the movable end corresponding to the other side of the 姊3G. The trigger 5 is permeable, and the rod 60 is connected to the second half 2° frame, the crankshaft 60 : There is a crank portion 6ι' for holding the hook portion 41 of the hook plate 40 to each other. As shown in the fourth figure, the integral folder is in the state in which the movable ends of the first and second halves W, 20 are closed, and is disposed at the end of the hook plate 40 opposite to the first; M348056 = 10. The hook portion 41 is mutually engaged with the upper crankshaft cymbal 60 disposed opposite to the second half 1 , and the crank rod 6 〇 is pressed and tightened in the trigger to gradually increase the interference course of the crank portion 61 against the hook plate 40: The first and second halves 10, 2 () are opened to ensure that the folding member lMJ is set in the extended state.
