Abstract
A mop structure of converting vertical linear displacement into unidirectional rotation for dewatering a mop comprises: a lower pipe with the bottom coupled to a mop head and the internal side fixed to a spiral rod; a driving pipe, having an interconnecting hole engaged with the spiral rod for passing the spiral rod and disposed at the internal side of the lower pipe, and a circular upwardly facing ratchet disposed at the top of the driving pipe; a fixing pipe, having a penetrating hole formed at the middle of the fixing pipe for passing the spiral rod and disposed at the top of the driving pipe, a circular downwardly facing ratchet installed at the top inside the fixing pipe and corresponding to the circular upwardly facing ratchet of the driving pipe, such that after the spiral rod is passed out from the penetrating hole, a fixing mechanism is provided for limiting the fixing pipe and the driving pipe on the spiral rod; and an upper pipe, with the bottom fixed to the fixing pipe after the bottom of the upper pipe is extended into the lower pipe, and a fixing mechanism for adjusting an extending/contracting length being installed between the upper pipe and the lower pipe.
