A cylindrical tubular traction portion 12 is installed on outside of the main rod 11. The traction portion 12 includes a straight tubular main body 120 and a spiral part 121 scattering at slightly spiral locations on the surface of the main body 120. A connecting part 122 is integrally formed with the main body 120 of the traction part 12 at the end away from the grip 10. The connecting part 122 is in shape of bell with connection mechanism of double flanges on outside of the bell, a stop part 123 in shape of dent is implemented on the outer flange of the bell which is used for a mop body 14 to be connected with and turned securely with the traction portion 12. A connecting base 13 is installed on the end of the main rod 11 coming out of the bell of the traction portion 12. The mop body 14 in shape of strips is installed in-between the connecting base 13 and the connecting part 122. A moving grip 15 is installed on outside of the traction portion 12, on the inner wall of the moving grip 15, a turning part 150 is formed as inner thread to match with the spiral part 121 of the traction portion 12, so that a user can hold with one hand on the moving part 15 letting the traction portion 12 turn the mop body 14 together with the main rod 11, with the created centrifugal force the mop body 14 will be spread outward for easy mopping.

The main features of this invention are:

The main rod 11 is a tubular structure, on which a puncture of retaining part 110 is made at suitable location wherein a retaining device 20 is installed. The retaining device 20 includes a retaining stud 21, which is in the form of a cylindrical rod penetrating through the retaining part 110 from inside of the main rod. An elastic push part 22 in shape of < is installed on the end of the retaining stud 21 inside the main rod 11 with which to provide elasticity for the retaining stud 21 to be retracted or extruded from the retaining part 110.

The inner wall of the tubular main body 120 of the above-mentioned traction portion 12 has a plurality of return stops 30, which is composed of a guiding part 31 with slanted surface and a barricading part 32 perpendicular to the inner wall of the main body 120. When a user holds on the moving grip 15 to move the moving grip 15 from the side of the connecting part 122 of the traction portion 12 toward the side of the grip 10.

Meanwhile, as shown in FIGS. 4 to 5, the turning part 150 on the inner wall of the moving grip 15 would cooperate with the spiral part 121 of the traction portion 12 to rotate the traction portion 12, in the mean time user's the other hand holds on the grip 10 keeping the main rod 11 still, the mop body 14 is in a twisted status with its one end staying still and the other end rotated, and at the same time of the mop body 14 being wrung dry, the retaining stud 21 of the retaining device 20 is sliding over the guiding part 31 of the return stops 30 and performing jump-over actions.

When the moving grip 15 stops moving, the wringed mop body 14 would create a reacting force on the traction portion 12, nonetheless the barricading part 32 of the return stops 30 would be barricaded by the vertical edge of the retaining stud 21 of the retaining device 20 and retain reacting force, therefore the mop body 14 would be securely kept wringing dry. When the moving grip 15 is pushed toward the traction portion 12, since the turning part 150 of the moving grip 15 and the spiral part 121 on the traction portion 12 are threaded tight with each other. The user holds on the moving grip without turning it, and the traction portion 12 is also not turning because the retaining device 20 is barricading it from rotation. The traction portion 12 is only allowed to move along with the direction of the moving grip 15 being pushed, and at the same time water is wrung out of the mop body 14, the effect of wringing dry is increased. When the traction portion 12 leaves the retaining device 20, the traction portion 12 would be free to be rotated.

Assembly of the connecting base 13, the main rod 11 and the mop body 14 of this invention is as shown in FIGS. 1 to 3. A push-tight part 132 in shape of guiding cone is provided on the connecting base 13 at corresponding location with the main rod 11.
