A flower bed mobile vehicle is composed of a handlebar, a cross beam, a rotary disc, a locating nut, a lead screw, a stabilizing ferrule, a push-and-pull pin, wheels, an axle, swing arms, axle sleeve pins, chain bars, embracing tiles, and the like. The lead screw is installed on a frame formed by connecting the handlebar with the cross beam and the axle, the rotary disc arranged on the lead screw is rotated so that the lead screw can have forward or backward displacement relative to the locating nut, and the push-and-pull pin drives the embracing tiles connected by the chain bars and the swing arms to be opened or closed. Movable pins on the embracing tiles enable a flower bed which is lifted by being embraced to keep non-inclined and perpendicular, and the flower bed can be easily carried and transferred to any place with the handlebar pressed by hand.
