Abstract
A fixing device for a wheel of a baby stroller utilizes an axle hole of the wheel formed to receive a rotation axle provided with a recessed neck. The device includes a sleeve provided in the axle hole of the wheel with a receiving chamber. The sleeve includes a pipe to receive the rotation axle. A spring loaded push button is also provided in the receiving chamber. When the push button is pushed down to force positioning rods to slide in inclined slots of the push button, the positioning rods exit a recessed neck of the pipe, and the wheel can be removed from the rotation axle. The device allows fast assembly and disassembly of the wheels so that a customer can maintain and change the wheels by himself. The device also allows the reduction of volume for packaging to increase shipping capability.
