The utility model discloses a floor mopping part of a floor mopping machine, which comprises a group of sticks including a floor mopping stick, a driving stick, an extrusion stick and a guide stick, as well as floor mopping toweling cloth and a rubbish drawer, which are all installed in a casing. The floor mopping stick is near to the ground at the underside and is wound with the floor mopping toweling cloth on the surface; the driving stick and the extrusion stick are parallel and near and are arranged in the middle; and the guide stick is arranged at the uppermost. The floor mopping toweling cloth is connected end to end after winding the floor mopping stick and the guide stick and passing through a gap between the driving stick and the extrusion stick. When a motor drives the floor mopping toweling cloth to circularly run while driving the driving stick through a driving mechanism to rotate, the floor mopping toweling cloth mops the ground. Two ends of each stick are respectively wound with a plastic thread gluing which glues two sides of the floor mopping toweling cloth. Two ends of the guide stick are respectively provided with a raised round ring which prevents the plastic thread gluing from moving and also prevents the floor mopping toweling cloth from moving. A layer of plastics or rubber is glued on the back of the floor mopping toweling cloth, thus a towel is more level.
