A socket adapted for electrically connecting the chip module to a printed circuit board includes an insulative housing, a plurality of contacts receiving in the insulative housing, and a fastening structure. The fastening structure includes an upper lever and a lower lever related to each other; wherein the upper lever includes an upper axis pivoted to the first object, an upper press portion rotatable about the upper axis, and an upper operation portion; the lower lever includes a lower axis pivoted to the first object, a lower press portion rotatable about the lower axis, and a lower operation portion. Whereby the upper operation portion of the upper lever moves downwardly so as to carry the lower operation portion of the lower lever downwardly, thus, the upper and lower press portions suppress the chip module simultaneously.
