A flexible utility handle comprising a handle, an upper tubular section having a female threaded first end and a recessed second end, a lower tubular section having a recessed first end and a male threaded second end, a coiled spring flexibly connecting the upper tubular section and the lower tubular section, and a tension cable operationally connecting the handle and the lower tubular section. The handle includes a cable tension bolt which is operationally designed to engage the female threaded first end of the upper tubular section. Rotating the handle to increase the overall length of the invention decreases its flexibility at the coiled spring. Rotating the handle to decrease the overall length of the invention increases its flexibility at the coiled spring.

1. A flexible utility handle comprising: an upper tubular section having a female threaded first end and a recessed second end;a lower tubular section having a recessed first end and a male threaded second end;a handle operationally designed to rotatably engage the female threaded first end of the upper tubular section;a coiled spring having a first end and a second end, the coiled spring flexibly connecting the recessed second end of the upper tubular section and the recessed first end of the lower tubular section; anda tension cable with a first end and a second end, said tension cable is operationally associated and secured at its first end to the handle, traveling within the upper tubular section, within the coiled spring, and within the lower tubular section, and secured at its second end with an anchor means to the lower tubular section wherein the tension cable selectively provides an axial force to compress the coiled spring axially between the upper and lower tubular sections. 2. The flexible utility handle of claim 1, wherein said recessed second end of the upper tubular section comprising a cable centering washer operationally configured to engage the first end of said coiled spring, said cable centering washer having a central aperture to receive and permit the passage of said tension cable. 3. The flexible utility handle of claim 1, wherein said recessed first end of the lower tubular section comprising a cable anchor washer operationally configured to engage the second end of said coiled spring, said cable anchor washer having a central aperture to engage said anchor means of the tension cable. 4. The flexible utility handle of claim 3, wherein said central aperture of said cable anchor washer being operationally configured to engage the anchor means to secure the second end of the tension cable within the lower tubular section. 5. The flexible handle of claim 1, wherein said male threaded second end of the lower tubular section being operationally designed to detachably attach one of a plurality of individual cleaning devices having a female threaded attaching means. 6. The flexible utility handle of claim 1, wherein said handle comprising a first end and a recessed second end, wherein said first end having a horizontal aperture, and wherein said recessed second end being configured to receive and secure a cable tension bolt within the recessed second end so that said cable tension bolt turns rotationally with said handle to engage the female threaded first end of the upper tubular section, whereby a rotation of said handle in one direction decreases said axial force and rotation of said handle in an opposite direction increases said axial force. 7. The flexible utility handle of claim 6, wherein said cable tension bolt comprising: a flat circular head configured to be received and secured inside the recessed second end of the handle, said flat circular head includes a threaded radial aperture housing an allen set screw;a threaded male end operationally designed to engage the female threaded first end of the upper tubular section; anda central channel longitudinally traversing said cable tension bolt, said channel being designed to receive the first end of the tension cable. 8. The flexible utility handle of claim 7, wherein said allen set screw being operationally configured to engage and secure the first end of the tension cable. 9. The flexible utility handle of claim 1, wherein said coiled spring comprising an inner rubber core extending there through, said inner rubber core having a central channel longitudinally traversing said inner rubber core to receive and permit the passage of said tension cable. 10. The flexible utility handle of claim 1, wherein said first end of the upper tubular section includes a gripping means. 11. The flexible utility handle of claim 1, wherein the tension cable comprising a length sufficient to permit the coiled spring to bend. 12. The method of using a flexible utility handle comprising the steps of: providing a flexible utility handle comprising: an upper tubular section having a female threaded first end and a recessed second end;a lower tubular section having a recessed first end and a male threaded second end;a handle operationally designed to rotatably engage the female threaded first end of the upper tubular section;a coiled spring having a first end and a second end, the coiled spring flexibly connecting the recessed second end of the upper tubular section and the recessed first end of the lower tubular section; anda tension cable with a first and a second end, said tension cable is operationally associated and secured at is first end to the handle, traveling within the upper tubular section, within the coiled spring, and within the lower tubular section, and secured at its second end with an anchor means to the lower tubular section wherein the tension cable selectively provides an axial force to compress the coiled spring axially between the upper and lower tubular sections;attaching a female threaded cleaning device to the male threaded second end of the lower tubular section;rotating the handle so that the cable tension bolt advances into the female threaded first end of the upper tubular section to provide flexibility to the coiled spring by decreasing the length of the flexible utility handle to reduce the axial force on the tension cable; androtating the handle so that the cable tension bolt advances out of the female threaded first end of the upper tubular section to provide rigidity to the coiled spring by increasing the length of the flexible utility handle to increase the axial force on the tension cable. 13. The method of claim 12, wherein said recessed second end of the upper tubular section comprising a cable centering washer operationally configured to engage the first end of said coiled spring, said cable centering washer having a central aperture to receive and permit the passage of said tension cable. 14. The method of claim 12, wherein said recessed first end of the lower tubular section comprising a cable anchor washer operationally configured to engage the second end of said coiled spring, said cable anchor washer having a central aperture to engage said anchor means of the tension cable to secure the second end of the tension cable within the lower tubular section. 15. The method of claim 12, wherein said handle comprising a first end and a recessed second end, wherein said first end having a horizontal aperture, and wherein said recessed second end being configured to receive and secure a cable tension bolt within the recessed second end so that said cable tension bolt turns rotationally with said handle to engage the female threaded first end of the upper tubular section, wherein said cable tension bolt comprising a flat circular head configured to be received and secured inside the recessed second end of the handle, said flat circular head includes a threaded radial aperture housing an allen set screw, said allen set screw being operationally configured to engage and secure the first end of the tension cable;a threaded male end operationally designed to engage the female threaded first end of the upper tubular section; anda central channel longitudinally traversing said cable tension bolt, said channel being designed to receive the first end of the tension cable. 16. The method of claim 12, wherein said coiled spring comprising an inner rubber core extending there through, said inner rubber core having a central channel longitudinally traversing said inner rubber core to receive and permit the passage of said tension cable. 17. The method of claim 12, wherein the tension cable comprising a length sufficient to permit the coiled spring to bend.
