A double blade peeling device for vegetable and fruit comprises a handle attached to a vegetable and fruit retaining member and a body of screw, the handle can drive internal gears to rotate, so as to make the retaining member and the body of screw to rotate as well. The body of screw, which is provided with two screw threads, drives upper and lower blade carriers to move upward and downward oppositely, such that the blades mounted on the upper and lower blade carriers move downward and upward respectively, contact the rotating food frictionally, and peel vegetable or fruit from upside and underside simultaneously. When two blade carriers move to the intermediate position to complete the peeling action, the two blade carriers open through wedge in blade carrier devices, two blades leave the surface of food, the lower blade carrier devices disengage with the body of screw. The body of screw drives upper blade carrier device to press the lower blade carrier device to move downward unceasingly. When the upper and lower blade carrier devices move to bottom, if turning handle, the two blade carrier devices and the body of screw slip on the spot, that is a protective function, and a peeling cycle is completed. The invention can peel a vegetable or fruit conveniently, quickly and exactly, its operation is safe.
