The folding bicycle 20 12 includes an upper tube 121, a front wheel 122, and a rear wheel 123 in addition to the joint structure 10. A grip 124 and another joint structure 60. Referring to the second to fifth figures, the first tube member 20 is pivotally connected to the second tube member 30 by a pivot shaft 36, and one end thereof is provided with a left inner arm 22 and a right inner arm 24 parallel to each other. The left inner arm 22 has a left arc hole 221, a front plug 6 M321000 hole 223, a rear jack 225, a front pillar 227 and a rear pillar 229. The front and rear jacks 223 and 225 are elongated holes. And disposed between the two ends of the left arc hole 221 and the pivot shaft 36, the front and rear protrusions 227, 229 are disposed on the other side of the left arc hole 221, and the right inner arm 24 has a right arc hole 24 a front protrusion 247 and a rear protrusion 249. The shape of the right arc hole 241, the front protrusion 247 and the rear protrusion 249 are respectively opposite to the left inner arm 221 and the front protrusion 227. And the rear pillar 229 corresponds. One end of the first official member 30 is provided with one of a left outer arm 32 and an outer #34 parallel to each other, and the left and right outer arms 32, 34 are separated from the first and second tubular members 2G by the pivot % The inner arms 22, 24 are pivotally connected. The left outer arm 32 has a left and a beacon hole 323. The through hole 323 is an elongated hole and a w wire 324 having a right through hole 341 and The left opening and the opening 2 position correspond to each other. In addition, the ends of the left and right outer arms 32, 34 are respectively 15 $ 325, 345, and the top 325 of the left outer arm 32 is located before the left inner #22, the rear convex column Between 227, 229, between the right inner arm 24 and the rear post between the tearing: 22^^" 4^ is disposed in the left and right arc holes of the first tube 20, the second tube ^^2 The left and right perforated milk of the pipe fittings are corrected, so that when the continuation of the first-(four) 姊3 6 miscellaneous turns the tree, the miscellaneous rod 40 is moved to the left and right arc holes 22U41, the moving rod 40 ^ One end of the arm 34 is provided with an external thread. The fixing member 42 is disposed at one end of the moving rod 40 and is located at the second portion and is movable therewith. The turning member 42 has a screw hole 421, 20 M321000. The wrench piece 44 is pivoted by a rotating shaft 441. The other end of the moving rod 4 is located outside the left outer arm 32 of the second tube member 3〇, and the rotating shaft is eccentrically disposed at the end of the wrench piece 44--, and its axial direction and the moving rod 4〇 Vertically, an outer surface of the wrench piece 44 is formed with a curved surface 443 on the rotating shaft 441. The positioning member 46 is sleeved on the moving rod 40 and is disposed between the wrench piece 44 and the left outer arm 32 of the second tube member 30. The positioning member 46 is provided with a ^ 榫 461 inside, and the outer side is provided There is a concave surface 463 which can be attached to the curved surface 445 of the wrench sheet. Wherein, the positions of the front and rear pillars 227, 229, 247, 249 of the first pipe member 20 are matched with the front and rear insertion holes 223, 225, and when the second pipe member 3 is abutted against the top portions 325, 345 and the two front pillars 227, 247, the positioning The card 461 of the member 46 can be inserted through the through hole 323 of the left outer arm 32 and inserted into the insertion hole 223 of the left inner arm 22, when the second tube member 3 abuts the top 325, 345 and the second When the studs 229 and 249 abut, the latches 5 461 of the positioning member can be inserted into the through holes 323 of the left outer arm 32 and inserted into the insertion holes 225 of the left inner arm 22 . The elastic member 48 is sleeved on the moving rod 4 and is a compression spring. The elastic member 48 is abutted against the locking member 42 and the positioning member 46 by the two inner ring 481 and the second outer ring 483. The two outer ring 483 sleeves & 2 〇 the moving rod 40, and are accommodated in the left and right arc holes 221, 2 of the first tube member 20 and the left and right perforations of the second tube member 30, 321 The two outer connecting rings 483 are not in contact with the locking member 42 and the positioning member 46. The two inner connecting rings 481 are sleeved with the moving rod 40, and are located between the two outer connecting rings 483 and the elastic member 48. When the user moves the wrench 44 downward, the elastic 8 M321000 48 can push the positioning member 46 outward, and when the user again pulls the wrench 44 upward. The wrench piece 44 can move the positioning member 46 inward. Through the above configuration, when the folding bicycle 10 is deployed, the latch 461 of the positioning member 46 is simultaneously inserted into the through hole 323 of the left outer arm 32 and the insertion hole 225 of the left inner arm 22, so The first and second tubular members 20, 30 can be effectively prevented from rotating relative to each other, and the first and second tubular members 20, 30 can be more reliably maintained in a fixed position; # When the second tubular member is required to be folded, use The wrench piece 44 can be pulled downward, as shown in FIG. 6 and FIG. 7 , so that the elastic member 48 pushes the positioning member 46 outward, thereby disengaging the latch 461 of the positioning member 46 from the first tube member. After 2 插孔, the jack 225, at this time, the user can apply force to rotate the second tube 30 in the clockwise direction of the seventh figure, so that the left and right outer arms 32, 34 abut the top 325, 345 and the first The ribs 227, 247 of a tube member 20 abut (as shown in the eighth figure), and the wrench piece 44 I5 is again pulled to move the positioning member 46 inwardly, so that the cassette 461 is inserted into the insertion hole 223 before the left inner arm 22 , the first and second pipe members 2〇, 3〇 can be maintained at a fixed position again to complete the folding, at this time, due to the positioning member 46 While the tongue 461 disposed through the left through-hole 32 of the outer arm 323 and the left before insertion hole 22 into the inner arm 223, and therefore the same can reliably about the first and second tubular member in a fixed position to maintain 2,020,530. In addition, since the front and rear insertion holes 223 and 225 of the left inner arm 22 and the through holes 323 of the left outer arm 32 are both elongated holes, the front and rear jacks are opened during the user's pulling of the wrench piece 44. The 223, 225 and the through hole 323 can allow the positioning member 46 to be pushed by the wrench piece 44 to slightly move the wrench piece 44 along the long axis 324 of the through hole M321000. Move back and forth, so that the user can smoothly pull the two hearts 2, the first picture, the ninth picture and the tenth picture, the fifth paragraph of the second creation: the provided joint structure 60 for the folding bicycle and = 2. In 2 cases, the joint structure 10 is substantially the same, and has the same - first two, one tube member 62, a moving rod 63, a locking member (not shown), a hand piece 64, a positioning member 65 and an elastic The difference (4) is that the first tube member 61 and the second tube member 62 for the joint structure of the folding bicycle are the folding bicycle 12 rear fork 61 and the seat tube ίο 62, respectively. Based on the spirit of the present invention, the joint structure for the folding bicycle is also changed, and the first preferred embodiment is taken as an example. The first tubular member 2 〇 front and rear projections 227, 229, 247, 249 and the second tubular member The first and second abutting tops 325, 345 of the 30 may also be provided as needed. The front left arm 22, the rear opening 223, 225 and the through hole 323 of the left outer arm 32 may each be a circular hole.
