[0030] A left basket frame 2 and a right basket frame 3 are axially connected to the main beam tube 1 . Furthermore, a rotating shaft 16 is provided between the vertical tube 15 and the front fork connecting tube 11 , and the left basket frame 2 and the right basket frame 3 are both axially connected to the rotating shaft 16 .

[0031] A basket lock 4 is provided on the vertical pipe 15 , and the basket lock 4 is used to lock the left basket frame 2 and the right basket frame 3 .

[0032] The basket lock 4 includes a lock block 41 and a U-shaped latch 42 . The lock block 41 is fixedly connected to the vertical pipe 15 . Furthermore, the lock block 41 includes a connecting portion 411 and a locking portion 412 . The connecting portion 411 and the locking portion 412 are assembled with each other on the vertical pipe 15 .

[0033] The connecting portion 411 and the locking portion 412 are fixedly connected by screws.

[0034] The ends of the left basket frame 2 and the right basket frame 3 are both provided with insertion holes 21 , and both ends of the U-shaped latch 42 pass through the locking block 41 and can extend from the locking block 41 to be inserted into the two insertion holes 21 respectively.

[0035] The connecting portion 411 is provided with a mounting hole 414 , and a return spring 5 is arranged in the mounting hole 414 . The return spring 5 always gives the U-shaped latch 42 a force to extend out of the mounting hole 414 .

[0036] A first locking piece 43 is provided on the U-shaped latch 42 . Furthermore, a first annular groove 421 is formed on the U-shaped latch 42 . The first locking piece 43 is stuck in the first annular groove 421 . A countersunk hole 413 is formed on the locking portion 412 . The first locking piece 43 is disposed in the countersunk hole 413 .

[0037] A second locking piece 44 is disposed on the U-shaped latch pin 42 . Furthermore, a second annular groove 422 is formed on the U-shaped latch pin 42 , and the second locking piece 44 is clamped in the second annular groove 422 .

[0038] Two ends of the return spring 5 are respectively mounted on the inner wall of the mounting hole 414 and the second locking piece 44 .

[0039] When the spring is in the expanded state, the first locking piece 43 is located in the countersunk hole 413 and abuts against the locking portion 412 , the second locking piece 44 is located inside the mounting hole 414 , and the end of the U-shaped latch 42 extends out of the mounting hole 414 .

[0040] The U-shaped latch 42 includes a grip portion 423 and an insertion portion 424 . Both ends of the grip portion 423 extend to form the insertion portions 424 . The two insertion portions 424 can be inserted into the two insertion holes 21 , respectively.

[0041] A blocking portion 415 is provided on the connecting portion 411, and grooves 416 adapted to the left basket frame 2 and the right basket frame 3 are respectively opened on both sides of the blocking portion 415. When the left basket frame 2 and the right basket frame 3 are in the retracted state, the left basket frame 2 and the right basket frame 3 are respectively located in the two grooves 416.

[0042] like Figure 4 As shown, the basket frame is in the unfolded state.

[0043] When the basket frame needs to be folded, the left basket frame 2 and the right basket frame 3 are rotated, and the hand grip 423 is pulled by hand, and the hand grip 423 drives the insertion portion 424 to be retracted into the installation hole 414. When the insertion holes 21 of the left basket frame 2 and the right basket frame 3 are aligned with the installation hole 414, the hand grip 423 is released, and under the action of the return spring 5, the insertion portion 424 is inserted into the insertion hole 21, and the left basket frame 2 and the right basket frame 3 can be fixed. Figure 1-3 shown.

[0044] When the basket frame needs to be unfolded, the hand grip 423 is pulled by hand, and under the action of their own gravity, the left basket frame 2 and the right basket frame 3 will automatically rotate to achieve unfolding. Figure 4 Status shown.
