Abstract

A sponge mop is composed of a handle, a lever, a rotary sleeve, a socket, a mophead seat, a sponge body, and two link rods. The lever and the mophead seat are connected by the two link rods. The lever is fastened pivotally with the handle which is in turn engaged at one end thereof with the rotary sleeve. The rotary sleeve is engaged at another end thereof with the socket which is in turn engaged at another end thereof with the mophead seat. As the rotary sleeve is rotated, the link rods are actuated by the handle to enable the mophead seat to swivel.
