Abstract:
1. An improved mop for retaining yarn, comprising: a. a handle having an upper section and a lower section, the lower section comprised of a hollow cylindrical wall having an upper end and a lower end, wherein a window is positioned below the upper end of said wall, and exterior spiral threads are positioned on the wall and below the window, said lower end is comprised of a transverse bottom plate which is divided by an identical first and second longitudinal slot to form an identical first and second segment which are connected to each other by a transverse beam, said first and second slots forming elongated slots extending longitudinally along the cylindrical wall to a location close to said exterior threads, wherein a first transverse slot on the wall intercepts the first elongated slot, and a second transverse slot on the wall intercepts the second elongated slot; b. a sleeve having interior threads rotatably surrounding said lower section of said handle; c. a piston assembly which is positioned inside of the said handle lower section comprising a piston, a spring and a stopper, the piston is positioned close to the lower end of said lower section, said spring is positioned so that opposite ends respectively contact said piston and stopper, a position of said stopper is affixed by said window of said lower section; d. a first and second clamp member comprising the respective upper and lower section, said upper section of said first clamp member comprising a first longitudinal upper end, wherein a first transverse axle is transversely connected to a position which is lower than said first upper end, said lower section of the first clamp member is comprised of a plurality of brushes, said upper section of said second clamp member comprising a second longitudinal upper end, wherein a second transverse axle is transversely connected to a position which is lower than said upper end, said lower section of the second clamp member further comprising a scrubber; e. said first longitudinal upper end of said first clamp member is installed into said first longitudinal slot to contact said piston, wherein said first transverse axle is positioned inside of said first transverse slot, said second longitudinal upper end of said second clamp member is installed into said second longitudinal slot to contact said piston, wherein said second transverse axle is positioned inside of said second transverse slot; and f. rotation of said in the clockwise directions serves to close said first and second clamp member to thereby hold the yarn between the clamp members, wherein said respective upper ends of respective first and second clamp members which rotatably move outwardly relative to each other press upwardly against said piston which presses said spring which is thereby compressed, rotation of the sleeve in the said sleeve in the counterclockwise direction opens said first and second clamp members to thereby release said yarn, wherein said respective upper ends which rotatably move inwardly to each other are pushed downwardly by said piston which is pushed by said spring which is expanding.
