In a preferred embodiment, the mop further includes a casing pipe, the said casing pipe is mounted inside the said screw pipe.

In a preferred embodiment, the said water squeezing mechanism includes hand grip, clamping holder base, left and right pull rods, left and right support rods, connecting block, universal base and left and right base plates, the said mop head includes firmly connected head and fixing board, the said fixing board is connected with the said left and right base plates, the said clamping holder base is rivet connection with the lower end of the said mop rod, the upper end of the said hand grip is rivet connection with the said mop rod, the lower ends of the said left and right pull rods are connected with the upper end of the said connecting block, the upper ends of the said left and right pull rods run through the lower side of the said clamping holder base, and riveted onto the said hand grip; the said left and right base plates are respectively pin-connected with left and right sides of the said connecting block; the upper ends of the said left and right support rods are respectively pin-connected to both sides of the lower ends of the said clamping holder base, while their lower ends are pin-connected with the upper side of the said universal base, the lower side of the said universal base is pin-connected with the upper sides of the said left and right base plates.

As the present invention has adopted the above-mentioned technical structure, when using, straighten the upper rod and lower rod of the mop rod, and make the screw sleeve and screw pipe into fixed connection, so as to keep the mop be a tightly connected whole for cleaning use. When the time comes for storage or transport, separate the screw sleeve from the screw pipe, fold the upper rod and lower rod along the connecting rod, in this way, the length of the mop after folding is nearly half of that of the whole mop before folding, which can greatly reduce mop's transport volume and storage space, thus facilitating storage after usage and product transport, with the added advantage of reduction of transport cost. Mounting casing pipe inside the screw pipe can further improve the strength of the screw pipe, as well as the sturdiness of the mop in usage. In addition, with the adoption of universal base structure, the riveting points between upper ends of left and right pull rods and griping handle, the connection points between lower ends of left, right pull rods and the connection block, as well as the connection points between lower ends of left, right support rod and universal base, line together to form a triangle structure. As a result, during actual usage, the mop head can maintain a steady tilt angle, therefore increasing the contact area between the bottom of mop head and the floor, thus effectively improving cleaning results.
