What is claimed is: 1. A food processor cover comprising: an upper cover surface; a feed tube which extends upwardly from the upper cover surface; a safety rod assembly disposed on the outside of the feed tube, said safety rod assembly including an operating rod and a rod spring; a feed tube lid assembly including a feed tube lid pivotally mounted on the feed tube, and a movable sleeve; wherein said feed tube lid includes a through hole at an upper end thereof for receiving the movable sleeve inside the feed tube lid and enabling axial movements of the movable sleeve therein; wherein each end of the movable sleeve includes a limiting device, and the top of said movable sleeve forms a safety food entrance defined by a major axis and a minor axis, with an average of the major and minor axes being less than 2.5 inches (63.5 mm) and the major axis being less than 3 inches (76.2 mm); wherein said limiting device includes an upper limit ring and a lower limit ring respectively shaped in oval; wherein said upper limit ring and lower limit ring are integrally fixed on said movable sleeve; wherein the outer dimensions of the upper and lower limit rings are slightly larger than that of the through hole of the feed tube lid; wherein at least one protruding member is disposed at a bottom surface of the lower limit ring; wherein the periphery of said feed tube lid extends downwardly forming a lid brim with dimensions larger than that of the feed tube; wherein an upward edge of the through hole of the feed tube lid forms an upward neck; wherein said lid brim has a protruding member positioned to correspond with the operating rod; and wherein a square concave recess is disposed in the lid brim above said protruding member; and a locking device disposed on an upper end of said safety rod assembly; whereby when the feed tube lid assembly is in a closed state, the feed tube lid covers the feed tube, and the protruding member of the feed tube lid presses down the operating rod; and when the feed tube lid assembly is in an open state, the operating rod is urged to reset by means of the rod spring. 2. The food processor cover according to claim 1, wherein the cross sections of the feed tube lid and the through hole are both in similar shapes selected from the group consisting of an oval and a circle, and said movable sleeve has a tubular structure formed by a thin wall whose cross section is in a shape selected from the group consisting of an oval and a circle. 3. The food processor cover according to claim 1, wherein said safety rod assembly includes a boss for holding the operating rod and a rod upper end; wherein said boss is integrated on an outside of the feet tube; and wherein said rod spring is mounted on the operating rod which is disposed inside the boss, and the rod upper end is positioned at the top end of the boss, so that said operating rod can move up and down inside the boss in the direction of the cover central axis. 4. The food processor cover according to claim 3, wherein a lower part of the operating rod is formed into a cylinder onto which said rod spring is mounted so that the operating rod can be urged to reset automatically without external forces. 5. The food processor cover according to claim 3, wherein said rod upper end is fixed on the top end of the boss forming a sealed cavity within the boss, whereby the operating rod is restricted to move within the sealed cavity of the boss. 6. The food processor cover according to claim 3, wherein said feed tube and the boss extend upwardly in the direction of the cover central axis; and wherein the cross section of said feed tube is in a shape selected from the group consisting of an oval and a circle. 7. The food processor cover according to claim 1, wherein said locking device includes: a press button which locks with the operating rod upper end by use of two lock pins which are disposed under the right and left sides of the press button; a press button spring disposed under the press button by which the press button can move relatively inside a boss in the direction vertically to the cover central axis; and wherein when the feed tube lid covers the feed tube, the press button is locked into a square concave recess formed in the feed tube. 8. A food processor comprising: a cover as claimed in claim 1, a rotating blade tool including a rotating shaft, a working bowl disposed under the cover and to be used in combination with the cover, and a base housing to support the working bowl including a driving device therein with a shaft; wherein the rotating shaft of the rotating blade tool is connected with the shaft of the driving device, which is disposed under the feed tube inside the working bowl; and wherein when the feed tube lid covers the feed tube, the operating rod is pressed down to actuate the driving device. 9. A food processor cover comprising: an upper cover surface; a feed tube which extends upwardly from the upper cover surface; a safety rod assembly including an operating rod, a rod spring and a boss for holding the operating rod and a rod upper end, wherein said boss is integrated on an outside of the feed tube, wherein said rod spring is mounted on the operating rod which is disposed inside the boss, and the rod upper end is positioned at the top end of the boss, so that said operating rod can move up and down inside the boss in the direction of the cover central axis; a feed tube lid assembly pivotally mounted on said feed tube, said feed tube lid assembly includes a safety food entrance defined by a major axis and a minor axis, with an average of the major and minor axes being less than 2.5 inches (63.5 mm) and the major axis being less than 3 inches (76.2 mm); and a locking device disposed on an upper end of said safety rod assembly, said locking device includes a press button and a press button spring, wherein said press button locks with the operating rod upper end by use of two lock pins which are disposed under the right and left sides of the press button, the press button spring is disposed under the press button by which the press button can move relatively inside the boss in the direction vertically to the cover central axis; whereby when the feed tube lid assembly is in a closed state, the feed tube lid covers the feed tube, the press button is locked into a square concave recess formed in the feed tube so as to compress down the operating rod, and when the feed tube lid assembly is in an open state, the operating rod is urged to reset by means of the rod spring. 10. A food processor comprising: a cover as claimed in claim 9, a rotating blade tool including a rotating shaft, a working bowl disposed under the cover and to be used in combination with the cover, and a base housing to support the working bowl including a driving device therein with a shaft; wherein the rotating shaft of the rotating blade tool is connected with the shaft of the driving device, which is disposed under the feed tube inside the working bowl; and wherein when the feed tube lid covers the feed tube, the operating rod is pressed down to actuate the driving device.
