New description: 【New technology field】 This creation department provides a technical field of finger-folding bicycles, especially its technology:: Provides a folding bicycle towing rear wheel steering structure, so that the bicycle stack is dragged The wheel is parallel to the wheel, and after folding, 1 is easy to tow, and then the tow can be directly kicked to be stowed. [Prior Art] According to the bicycle, although the bicycle has been invented for hundreds of years, people do not have a passion for bicycles. On the contrary, because of the current energy shortage and high oil prices, the sales of bicycles have increased greatly, although bicycles The benefits are quite townships. But there are also some problems. For example, the size of the bicycle is huge, and the white gt; z Φ zb is a self-driving car. The range of activities is limited, so if you want to extend the scope of its activities, you need to Other means of transportation assistance, such as transportation by train, train, MRT, etc., but it is difficult to load the truck with its truck, and the transportation of trains and MRT, some of the length and width of the bicycle The height is limited' so the bicycle is forced to develop towards the folding bicycle. If you want to directly move the folded car, it is difficult to directly move the folded/rut-like field. Therefore, there is a two-handed bicycle for the application of the previous case; the tow wheel is equipped with a tow wheel. The wheel is convenient for bicycles to know the upper and lower MRT, or to move the folding bike to the desired space. There are still 3 M381571 missing movements in the above-mentioned conventional folding bicycle structure: ...the conventional folding bicycle movement structure, after which the towing wheel system is perpendicular to the direction of the bicycle, so the rear towing wheel has The condition of the ground contact forms a resistance to the advancement of the bicycle or may be dangerous. ', and those who have towed the material from the back, when they are stowed, they are in the opposite direction to the person riding the foot and kicking the money. Therefore, it is quite inconvenient for the person to leave the car and to close the tow wheel by hand. practical. =, In view of the problems existing in the above-mentioned conventional structure, how to develop two innovative structures with more ideal and practicality, the consumers are looking forward to it, and the relevant industry must strive to develop the goal and direction of breakthrough. With this in mind, the creator has been engaged in related production and design experience for many years, and has been working on the above-mentioned Xiaoyi. 1 Every development is finalized - practical and practical... After design and careful evaluation, the author has a practical and practical creation. [New content] / Technical problem to be solved: The folding bike is moved by the familiar, and the trailing wheel train is perpendicular to the L 4 direction of the bicycle. Therefore, if the trailing wheel is in contact with the ground, the meeting will be Form the resistance of the bicycle forward. The direction of the kick on the back of the car is reversed. In the direction of the =, the rider picks up the rear tow... "--It is quite inconvenient and practical to leave the car and use the wheel. The technical characteristics of the problem: provide a kind of folding self-wheel steering structure, which is aimed at the M381571 which is similar to the movement after the self-lighting, and the pfr juice is applied to the bottom of the bicycle. The tow side: perpendicular to the direction of travel of the bicycle, so that the tow wheel inadvertently touches the ground when the bicycle advances. 'There is a danger of forming a resistance direction or a bicycle traveling. Therefore, the present invention mainly has a front tow wheel structure. And the rear towing wheel structure, the rear towing wheel structure is up and down when the towing task is not performed
