Portable rod vehicle lock

A portable rod vehicle lock comprises a set of locking rods that rotate relative to a shaft for unlocking and locking through the rotational movement. When unlocked, the two locking rods can be rotated to an overlapping position via the shaft and significantly reduce the size of the lock for easy storage and portability. During the locking process, the two locking rods are also rotated around the shaft to extend, and the butt portions on the locking rods engage with the tire tread to form a stable triangular locking structure. The structure effectively stops the rotation of the wheel, and the operation is very convenient. Moreover, the entire lock will not contact the rim of the wheel during locking, preventing any damage to the rim surface.
