Since this quick release is a common structure, it will not be described in detail here. The money car body 4 can be moved between a use position and a collapsed position. As shown in the plate 3 3, in the use position, the sleeve 412 is set in two C-shaped openings 225 and connected to the order. The plate milk room, and through the quick-release A 44 clamping position, the set of f 412 is fixed to the connection plate milk front car = the linkage cradle 22 is connected, at this time, the rear bracket 41 is away from the rear wheel 42 and ^ wheel 42 are far away from the front wheel 32, and the walking wheel 43 is in a position without touching the ground, and at this time, it can be used for riding. As shown in the rear car ^ 7-, when the bicycle rides on uneven ground and let the material go up ^, because the rear wheel 42 is abutted by the ground, the rear bracket 41 will be linked with the shaft 214 as the center. Hour hand ~ and when the rear bracket 41 is swiveled, it will also drive the cradle 22 to drag the shaft 20 M254405 6 by buffering, which can be rotated counterclockwise by the clockwise rotation of 224 as the center, and press against the avoidance. Zhen Sang sets the quake. After the rear wheel 42 passes the uneven ground, the elastic force of the shock device 6 causes the cradle 22 and the rear bracket 4 J to rotate and reset. ίο 15 20 As shown in Figure 8, when you want to fold and store, first control the quick-release fixed connection unit material to the loose state, so that the sleeve 412 can leave the two swing plates 221 and the stern plate 222, and then make the The rear body 4 rotates clockwise around the shaft 214 as the center. When the rear bracket is adjacent to the front body 3 days and the rear wheel 42 # is close to the front wheel, the rear body 4 is in the closed position. At this time, the walking wheels will contact the ground and be located behind the rear wheel 42 to assist / move the heart. As shown in FIG. 9, the seat selection lever is buckled downward by the telescopic mechanism 23 until the seat 213 is lowered against the telescopic mechanism, and the front bracket 31 is pushed by the folding mechanism 33. After bending backwards, the abutment toward the connection talent 211 'thus completes the folding and folding of the bicycle. At this time, since the helper wheel 43 contacts the ground, it is easy to move. Conversely, if you want to ride a foot and step on a bicycle, you can use it by riding the above steps in reverse order and adjusting the rear body 4 to this use position, as shown in Figure 3. As shown in FIG. 10, it is the second preferred implementation of the new folding bicycle: 'This embodiment is substantially the same as the above embodiment, except that the main body 2 of this embodiment has a folding positioning sheet. It 24 is used for positioning the folded car body 4. The folding positioning unit 24 has a coupling seat 241 > a lever 242, and a torsion spring 243. This combination seat is the bottom of the connecting rod 211 of the lock body 2 and has two side walls 245 with a C-shaped recess 244 formed by two left and right vertical extension blades, and a C connected between the two recesses 244 of the side walls 245 of two M254405. An arc-shaped wall 246 and a spring block 247 with a slit formed on a front side of the arc-shaped wall 246. The elastic block 247 elastically protrudes toward one of the c-shaped openings 248 of the arc wall 246. The lever 242 is pivoted between two side walls 245 and has a buckle 249 protruding toward the rear side of the c-shaped opening 248 of the arc wall 246. Both ends of the torsion spring 243 abut against the combining seat 241 and the lever 242, respectively, and have an elastic force for pushing the buckle block 249 toward the C-shaped opening 248. Of course, in terms of design, the folding positioning unit M can also be assembled backwards and forwards, so that the lever 242 is located in the front, so that the 10 15 red bolt can be easily pushed. Further, the δ-H poster bracket 41 further has a clamping rod 415 connected between the two u-shaped rods 々η. 3 • ’. i ~ Γ π τ ~ 叩 々 疋 to obtain the main collapsed position τ P can use the folding unit 24 to position this collapsed body 4 after positioning, as shown in Figure u, turn the lever M2, The C # opening 248 of the buckle block 2 # is pressed against the torsion spring ⑷, so that it has the elastic force that drives the resetting of the wrench 242. At this time, the rear car body 4 can be rotated, and the yoke lever can be pushed up through the elastic block 247, and embedded in the c-shaped opening, and then release the lever 242, and the torsion spring 243 is reset by torque. Elastic force, turn: the top of the block to the C-shaped opening ° 248, with the elastic block 247 to buckle the lever 415, as shown in Figure 12. To use it out of the positioning state, press the lever 242 and pull out the lever 415. As can be seen from the above, the new penalty 々g is a treadmill, with the folding feet of the main body 2 and the front shock device. ^ _ The message that the limb 3 and the rear body 4 are foldable :: It can always make the space for the car to fold money, and when it is in the collapsed state, it can also help the rider to tow the bicycle by assisting with "3 and the ground 20 M254405 5". The Japanese taxi office is more famous. Furthermore, the new model is equipped with the shock absorber 6, so the shock absorption effect makes the bicycle more comfortable when riding. 1 This new model is not only an innovation that has not been seen in the past. It can be used in industry. However, the above are only the preferred embodiments of the new model, and the scope of the implementation of the new model cannot be limited by this, that is, the simplicity of the application of the new model: the scope of the benefit and the content of the new specification. The equivalent changes and modifications of the dagger should still fall within the scope of the new patent.
