Patent ID: 8407845

Claim:
A mop, comprising: a spinning member, comprising a first end, a second end opposite to the first end, and a spiral hole axially configured through the spinning member from the first end to the second end of the spinning member; a spiral rod comprising a first end and a second end, wherein the spiral rod is axially inserted through the spiral hole, and the spiral rod is further provided with a unilateral bearing sleeved over the spiral rod; an extendable rod, being a hollow member having a first end and a second end, wherein the second end of the extendable rod is tightly coupled with the first end of the spinning member; a mop head, coupled to the first end of the extendable rod; and a pressing rod, being a hollow member having a first end and a second end, wherein the spiral rod is sleeved inside the pressing rod, the first end of the pressing end is slidably coupled over the spinning member and the extendable rod connected with the spinning member, and the second end of the pressing rod is jointed with the second end of the spiral rod, wherein when the mop is put in a basket which is free for rotation, the pressing rod is then axially applied with a downward pressure, and the extendable rod is relatively withdrawn inside the pressing rod, the spinning member synchronously carries the extendable rod, the mop head and the basket to rotate, thus applying a centrifugal force to remove water content contained in the mop away from the basket.
