Abstract
Abstract A mop holder for a yarn-type mop head comprises a shank which is adapted for connection to a mop handle and an elongated member which has a threaded rod extending therefrom. The threaded rod includes an upper and a lower part. The lower part which is larger than the upper part is located intermediate the elongated member and this upper part. A nut is provided for engagement with the lower part of the threaded rod whereas the shank is adapted with an inner sleeve for screwable engagement thereof with the upper part of the threaded rod. The mop head comprises a grommet defined therein that is of larger transverse dimension than that of the lower part of the rod for being positioned therearound. Therefore the mop head is secured to the mop holder by way of the nut which is engaged in the rod while the shank ensures tightness of the nut.
