1. An apparatus for caring for a lawn, comprising: a cutting device comprising a support deck supporting a power source, a motor, and a cutting blade, the cutting device further comprising a sleeve for mounting the cutting device;a chassis for slidably receiving the sleeve and for carrying the cutting device above the lawn, the chassis defining a longitudinal axis and including a chassis body and wheels mounted on the chassis body; andan adjusting device for adjusting the height of the cutting device with respect to the chassis, which is arranged between the cutting device and the chassis;wherein the adjusting device comprises an adjusting seat connected to one of the chassis body and the cutting device, an adjustment driving device mounted on the adjusting seat, a driving member connected to the adjustment driving device, and a driven member connected to the driving member, wherein the driven member is connected to the other one of the chassis body and the cutting device,wherein actuation of the adjustment device causes the sleeve of the cutting device to slide relative to the chassis along the longitudinal axis of the chassis, thereby changing the distance between the cutting device and the lawn. 2. The apparatus as recited in claim 1, wherein the adjustment driving device comprises a motor. 3. The apparatus as recited in claim 2, wherein one of the driving member and the driven member has an internal threaded hole and the other one thereof has external threads which may be engaged with the threads of the internal threaded hole. 4. The apparatus as recited in claim 3, wherein the chassis body includes two side frames and a connecting rod for connecting the two side frames and one of the adjusting seat and the driven member is connected to the connecting rod of the chassis body. 5. The apparatus as recited in claim 1, wherein the driven member has a guide external surface and the adjusting seat has a guide internal surface which is arranged to contact with the guide external surface. 6. The apparatus as recited in claim 5, wherein the driving member has an axis, one of the guide external surface and the guide internal surface extends along a direction parallel to the axis. 7. The apparatus as recited in claim 1, wherein the driving member has an axis and the chassis body includes two side frames, wherein at least a portion of the surface of each side frame extends along a direction parallel to the axis of the driving member, and wherein the support deck is slidably connected to the portion of the surface of each side frame. 8. The apparatus as recited in claim 7, wherein each side frame of the chassis body includes a front portion and a rear portion onto which the wheels are mounted respectively, and a middle portion releasably connected to the front portion, to which the cutting device is slidably connected. 9. The apparatus as recited in claim 8, wherein the chassis body also includes at least one connecting rod for connecting the two side frames together. 10. The apparatus as recited in claim 9, wherein the chassis body includes two connecting rods for connecting the two side frames together and wherein one connecting rod is used as a front rod connected to the front portions of the side frames and the other connecting rod is used as a rear rod connected to the rear portions of the side frames.
