1. A telescopically rotatable mop, comprising:

  • a) an internal rod having a hollow body, a top portion, a bottom portion and an external diameter (D2);

    b) an external rod having a hollow body, an internal diameter (φ

    1) and a bottom portion in a telescopic connection with the top portion of the internal rod;

    c) an engaging element positioned within an opening at the top of the internal rod, the engaging element having at a bottom thereof a through hole and at an internal bottom rim a plurality of driven teeth;

    d) a driving element formed in an elongated shape and positioned within the external rod in such a way that the driving element is moved up and down synchronically with the external rod;

    e) an actuating element positioned within the engaging element with a threaded sleeve at a top thereof for accommodating the driving element, the actuating element having at a bottom thereof a plurality of driving teeth corresponding to the driven teeth of the engaging element for driving the engaging element in a single direction when the actuating element is rotated by the driving element;

    f) a fixing cap having a top, a bottom, a through hole for the insertion of the driving element, the fixing cap being mounted on the opening of the engaging element;

    g) a disc body secured to the bottom portion of the internal rod and having mop yarns;

    h) a locking mechanism mounted on the external rod for locking the internal rod and the external rod in place or for unlocking them in a telescopic state, wherein the engaging element is constructed as a cylindrical body with middle and lower parts secured inside of the internal rod, and an annular element having an external diameter (D1) where the annular element is rotatable clockwise and counterclockwise at 360°

    is mounted on a top portion of the engaging element projecting in an exposed manner from the internal rod, and the external diameter (D1) of the annular element is greater than the external diameter (D2) of the internal rod, but smaller than the internal diameter (φ

    1) of the external rod;

    wherein the portion of the driving element accommodated by the actuating element has a length (L1) smaller than length (L2) of an inside of the engaging element; and

    wherein the bottom of the fixing cap is extended and secured to the opening of the engaging element in such a way that a gap (S) is provided between the fixing cap and the top of the actuating element, and the fixing cap includes at the top thereof a projecting flange whose external diameter is greater than the external diameter of the internal rod, but smaller than the external diameter of the annular element) for positioning the annular element on the periphery of the top portion of the engaging element without affecting the rotation of the annular element within the external rod.
