1. An automatic water distributor comprising a body including a first outflow cavity and a second outflow cavity; the body also including at least one first inlet and at least one second inlet fixed between inner peripheral sides of the first and the second outflow cavities; the first inlet communicating with the first outflow cavity through a hole in the body; the body including a spaced fringe formed on an inner peripheral surface thereof to space the first and the second inlets, and the spaced fringe including a through aperture arranged thereon;a valve core inserting through the hole and the through aperture and including a first segment located at the first outflow cavity and a second segment located at the second outflow cavity;a water plug being capable of sliding on the valve core of the first outflow cavity;a first resilient element fitted on the valve core, including two ends abutting against the first segment and the water plug of the valve core respectively, and providing a shock absorbing effect when being compressed by the water plug;a second resilient element fitted on the valve core and including two ends abutting against the second segment of the valve core and the spaced fringe of the body individually, wherein an elasticity coefficient of the second resilient element is less than that of the first resilient element, the second resilient element pushes the valve core to move downward by using its returning elasticity so that the water plug on the valve core closes the hole of the body. 2. The automatic water distributor as claimed in claim 1, wherein the body further includes an upper part member and a lower part member, both of which are screwed with each other, an interior of the upper part member is used to define most part of the first outflow cavity, and an interior of the lower part member is applied to define the second outlet cavity, the lower part member includes the first inlet, the second inlet, the hole and the spaced fringe arranged thereon. 3. The automatic water distributor as claimed in claim 1, wherein the second segment of the valve core includes a fitting portion mounted thereon to slide upward and downward along the second outflow cavity of the body so as to divide the second outlet cavity into an upper room and a lower room, and volumes of the upper room and the lower room are changed with a movement of the fitting portion, the fitting portion includes a radial channel and an axial channel to communicate with the radial channel, and the radial channel communicates with the second inlet through the upper room, the axial channel communicates with the lower room. 4. The automatic water distributor as claimed in claim 3, wherein the valve core includes a fixing periphery fixed on an outer surface thereof above the radial channel so that the two ends of the second resilient element are biased against the fixing periphery and the spaced fringe respectively. 5. The automatic water distributor as claimed in claim 1 further including a check valve is screwed in the body relative to an outlet end of the second outflow cavity. 6. The automatic water distributor as claimed in claim 1, wherein the first segment of the valve core includes a retaining ring disposed thereon, a stop piece and a positioning seat, both of which are fitted on the first segment, and the two ends of first resilient element are biased against the stop piece and the positioning seat, the stop piece is limited by the retaining ring, and the positioning seat abuts against the water plug. 7. The automatic water distributor as claimed in claim 1, wherein the valve core includes a stepped rim disposed thereon to be abutted by the water plug being biased by the first resilient element. 8. The automatic water distributor as claimed in claim 1, wherein the water plug is formed in a cone shape to define a conical closing fence to close the conical peripheral face formed on a top end of the hole of the body. 9. The automatic water distributor as claimed in claim 1 further comprising a housing to receive the body, wherein the housing includes at least one third inlet arranged thereon to communicate with the first inlets and the second inlet. 10. The automatic water distributor as claimed in claim 9, wherein the housing includes an upper housing part, a valve holder fitted on a top end of the upper housing part, and a lower housing part fitted onto a bottom end of the upper housing part; the valve holder serves to receive a top end of the body and to communicate with a first watering device; the lower housing part is capable of receiving a bottom end of the body and to communicate with a second watering device. 11. The automatic water distributor as claimed in claim 10, wherein the third inlet is arranged on the lower housing part. 12. The automatic water distributor as claimed in claim 1, wherein the first resilient element is a compression spring. 13. The automatic water distributor as claimed in claim 1, wherein the second resilient element is a compression spring. 14. The automatic water distributor as claimed in claim 1, wherein the water plug is made of plastic material. 15. The automatic water distributor as claimed in claim 1, wherein the valve core is away from the hole to form a slit defined between the valve core and the hole so as to communicate the first inlet with the first outflow cavity.
