A telescopically rotatable mop, comprising: an internal and external rod fitting to each other in a linearly and telescopically movable state; an engaging element positioned within the opening at the top of the internal rod; 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; an actuating element positioned within the engaging element for accommodating the driving element, the engaging element being driven in a single direction when the actuating element is rotated by the driving element. An annular element rotatable clockwise and counterclockwise at 360° is mounted on the top portion of the engaging element. The actuating element received within the engaging element has a smaller length, thereby creating a gap for the lifting and lowering purposes. In this way, a more smooth operation with less effort is ensured when the internal and external rods rotate in a telescopic way. |
