The rotating bolts second and third also facilitate the rotation of the upper assembly. The bicycle and the portable bicycle stand are two separate entities, which improves its practicality.

[0028] 4. The portable bicycle stand cooperates with the support rod and the baffle. When not in use, the support rod can be rotated so that the support rod contacts the baffle. The baffle can contact the support rod, which can play a role of limiting and is also convenient for storage. At the same time, the fixing sleeve can be rotated so that the upper component is stored in the back of the box body, so that the entire stand can be stored into a smaller component, which not only improves portability but also reduces its occupied area.
