The control portion 151 passes through the elastic fixing member 153 and fixes the elastic fixing member 153 to the supporting rod 12' to thereby control whether the engaging portion 1 52 is disengaged from the elastic fixing member 153 by the opening 52 i. Further, the elastic fixing component 153 further includes a song

The surface control body 1531, a first fixing portion 1532, an elastic body 1 5 33 and a second fixing portion 1534. The control unit ι51 passes through the curved surface control body 1531. The first fixing portion 1 532 includes a first head portion 1538 and a first tube portion 1539. The first tube portion 1539 extends from the first head portion 1 5 3 8 and the first head portion 1 5 3 8 accommodates a portion of the curved surface control body 1531. The diameter of the first head 1 538 is greater than the opening 1521' of the fastening portion 152 and the diameter of the first tube portion 1539 is smaller than the opening 1 5 2 1 whereby the first tube portion 1 5 3 9 passes through the opening 1521. The second fixing portion 1534 includes a groove 1536, a second head portion 1535 and a second tube portion 1537. The second tube portion 1 5 3 7 substantially secures the elastic fixing member 1 5 3 to the M351180 branch rod 12. The tube portion 1 537 extends from the 1535, and the second head 1 535 is directly larger than the opening 1521 of the fastening portion 15^. The engaging portion 152 includes a first inlay portion 152a and the first head portion 1 538 includes a second inlaid person; 1 538a' thereby engaging the engaging portion 152 at the first - 1538.丨

The groove 1 536 receives a portion of the elastomer 1 533 and the first tube 1539 such that the elastomer 1 533 is positioned between the first tube portion 1539 and the groove 1 536. When the user removes or loosens the control portion 151, the elastic body 1 533 provides an elastic force to cause the first fixed portion 1 532 to be displaced, thereby controlling the engaging portion 152 to be disengaged from the opening 1521 from the elastic fixing member 153. As shown in Fig. 6 and 8, the user only needs to move the control unit in the direction of the arrow, so that the foot support rod 12 and the rear wheel support frame 13 are separated from each other. In the preferred embodiment, please return to the figure. 1. The frame 10 of the present invention may also include a separating member as described above. When the spring shaft 11 is extended, the pedal support rod 12 and the rear wheel support frame 13 can be separated by the separating member 15, and the frame 10 can be folded by the rotating portion 14. Further, the separating member 15 of the present invention is not limited to the structure as shown in the figure, in other words, the separating member 5 can be designed to be used in other parts such as a separation seat (not marked) and a frame ίο. In addition, the number f of the elastic fixing members 153 is not used to define the present creation. Although two sets of the elastic fixing members 153 are illustrated, in fact, as described above, a set of M351180 fixing members 153 can achieve the separation of the present creation. purpose.
