The embodiment further discloses a wheel fixing structure, which comprises a hollow pipe body 10; a hollow spring body 10 is provided with a spring 20; the spring 20 is sleeved with a movable shaft 30; and one end of the movable shaft 30 and the axle 50 are movable. The other end is abutted against the spring 20; the axle 50 can be sleeved into the interior of the hollow tubular body 10.

Optionally, the opening of the hollow tubular body 10 is sleeved with a cap 40; the diameter of the cap 40 is smaller than the inner diameter of the hollow nozzle; and the end of the spring 20 adjacent to the axle 50 abuts against the opening of the cap 40 edge. The cap sleeve 40 is screwed to the opening of the hollow tubular body 10. The detachment of the movable shaft 30 and the spring 20 can be facilitated by the cap 40, and can be matched with the movable shaft 30 to form a positioning structure of the spring 20.

The inner top surface and the bottom surface of the cap 40 are both flat 70; correspondingly, the upper surface and the lower surface of the movable shaft 30 are also flat surfaces 70, and cooperate with the inner top surface and the bottom surface of the cap 40 to form a limiting structure for restricting the rotation of the movable shaft 30. The movable shaft 30 is restrained by the inner diameter shape of the cap 40, and the rotation shaft 32 is prevented from rotating, so that the limit structure is not required in the hollow pipe body 10, and the manufacturing cost is reduced.

The length of the axle 50 is greater than the diameter of the cap 40. Thus, when the rotating shaft 32 is perpendicular to the cap 40, that is, when the wheel 60 is folded, the stress of the spring 20 is caught at the opening of the cap 40 to achieve automatic positioning.

An end of the movable shaft 30 fixed to the axle 50 is provided with a groove 31; a rotating shaft 32 is disposed between the inner walls of the groove 31; correspondingly, the axle 50 is embedded in the groove 31; the axle 50 is provided The through hole of the rotating shaft 32 is sleeved; when the axle 50 is rotated parallel to the movable shaft 30, the rotating shaft 32 can be inserted into the hollow tubular body 10 together with the movable shaft 30; when the rotating shaft 32 is rotated perpendicular to the movable shaft 30, the rotating shaft 32 is abutted Close to the opening of the cap 40.
