The joint unit has four joints, each of which includes a first, second and third lock. When the first lock is released, the handle frame may be folded towards the main frame. When the third lock is released, the front wheel and fork may be turned over. When the second lock is released, one of the joints is moved upwards and pushes the linking rod and two supporting rods to make the front wheel, front fork, two auxiliary supports and two rear wheels folded towards the main frame.
