A mop includes a handle; a base seat fixedly disposed at a bottom end of the handle; two links, top ends of the links being pivotally connected with two lateral sides of the base seat; and a compression seat including a pivot block and two compression boards pivotally connected therewith. Bottom ends of the links are pivotally connected with the compression boards. A foam rubber is disposed under bottom face of the compression seat. When shifting a shift lever, via a drive rod, the compression seat is moved into the base seat or moved out of the base seat and stretched to straighten the foam rubber. In the stretched state, the two links are tilted and a distance between bottom pivot points of the links is larger than a distance between top pivot points thereof. Outer lateral faces of the links abut against two lateral sides of the base seat as supports.
