An anchoring structure for a folding keyboard includes a first base, a second base and a linkage means. The first base has an upper surface which has a first key zone located thereon and an inner edge which has a first pivot joint located thereon. The second base has an upper surface which has a second key zone located thereon and an inner edge which has a second pivot joint located thereon. The first and second pivot joint engage respectively and pivotally with two edges of a linkage means so that the first and second bases and the linkage means may be folded and extended. The first and second bases have respectively a lower surface which has a slide channel located thereon and corresponding to each other to form a sliding path when the keyboard is extended. A slide block is located in one of the slide channel and movable reciprocally on the slide path. When the slide block is moved to the middle position between the two bases, it produces a constraint effect on the keyboard and allows the keyboard to be extended on a flat surface.
