[0061] In order to make the steering support 40 and the handle 41 rotate well, in the embodiment, the first inclined portion 42 and the second inclined portion 410 are combined Figures 3 to 6As shown, the first inclined part 42 is provided with an annular groove 421, the embedding hole 420 is arranged at the center of the annular groove 421, the second inclined part 410 is provided with a convex ring 412 with the same center as the handle rotating shaft 411, the convex ring 412 is arranged on the inner side of the annular groove 421 and the two are rotationally matched, the bottom of the handle rotating shaft 411 is provided with an angle limiting disc 413, the angle limiting disc 413 is provided with a semicircular limiting slot 414, the edge of the embedding hole 420 is provided with an angle limiting block 422, the angle limiting block 422 is arranged in the semicircular limiting slot 414 and the two are slidingly matched, the annular groove 421 is provided with a torsion spring 44, the two ends of the torsion spring 44 are respectively clamped on the first inclined part 42 and the second inclined part 410, and the torsion spring 44 provides elastic stress for the handle 41, so that the handle 41 can be automatically reset after the handle limiting mechanism 47 is unlocked.

[0062] In the above structure, the nested cooperation of the annular groove 421 and the convex ring 412 forms the effect of dynamic sealing, which can prevent sand, liquid and the like from invading the bearing, and can also inhibit the transverse rotation of the handle 41. Based on the angle limiting effect of the angle limiting block 422 and the semicircular limiting slot 414, the handle 41 can be rotated within a range of 180°, thereby realizing the functions of horizontal expansion and vertical storage.

[0063] Regarding the preferred structure of the handle 41, in combination with Figures 6 to 8 As shown, the handle 41 comprises a handle main body 45, a handle inner tube 46 and a handle limiting mechanism 47, the handle main body 45 is provided with a handle recess 450, the handle inner tube 46 and the handle limiting mechanism 47 are both inserted into the handle recess 450, the second inclined part 410 is fixed to the upper end of the handle inner tube 46, and the second inclined part 410 covers the upper end opening of the handle recess 450, the handle limiting mechanism 47 comprises a retractable lock tongue 470, the lock tongue 470 passes through the lock tongue hole 415 on the second inclined part 410 and the two are slidingly matched, the first inclined part 42 is provided with two locking holes 423 for the insertion of the lock tongue 470, and the two locking holes 423 are symmetrically arranged on the two sides of the annular groove 421. When the handle 41 is rotated to the horizontal position, the lock tongue 470 is inserted into one of the locking holes 423 for locking, and when the handle 41 is unlocked and rotated to the vertical position, the lock tongue 470 is inserted into the other locking hole 423 for locking again.

[0064] Further, the handle limiting mechanism 47 comprises a handle limiting seat 471, a lock tongue sliding block 472 and a pressing cap 473.

The outer inclined surface of the wedge-shaped driving tongue 475 is in sliding fit with the inner inclined surface of the wedge-shaped inner hole 477. The lock tongue 470 is arranged on the lock tongue sliding block 472. A lock tongue spring is arranged in the handle recess 450 to drive the lock tongue sliding block 472 and the lock tongue 470 to slide outwards. When the pressing cap 473 is pressed, the wedge-shaped driving tongue 475 drives the lock tongue sliding block 472 and the lock tongue 470 to retract into the handle recess 450.

[0065] In the above structure, when the pressing cap 473 is pressed, the wedge-shaped driving tongue 475 moves into the driving tongue sleeve 476.

[0069] Further, in combination with Figures 9 to 11 As shown in the figure, the pedal limiting mechanism 52 comprises a limiting pin 520. The limiting pin 520 is fixed to the bottom of the pedal fixing base 50. The end of the limiting pin 520 is formed with a limiting hook 521 which is bent towards the inside of the pedal fixing base 50. The bottom of the pedal body 51 is provided with a hook sliding groove 510. The limiting hook 521 is arranged in the hook sliding groove 510 and the two are in sliding fit. When the pedal body 51 slides out of the pedal fixing base 50, the limiting hook 521 is clamped at the first end of the hook sliding groove 510. Based on the sliding fit relationship between the limiting pin 520 and the hook sliding groove 510, the extension length of the pedal body 51 can be limited.

[0070] On this basis, when the pedal body 51 is retracted, in order to lock the pedal body 51 at the retracted position, in the embodiment, the second end of the hook sliding groove 510 is provided with a self-locking mechanism 511 for locking or unlocking the limiting hook 521.
