A locking system for connecting a handle and an implement is provided. The locking system includes a handle having a first thread and a first locking member and an implement having a second thread and a second locking member. The first and second threads are threadably engaged so that the first and second locking members selectively lock the handle to the implement.

What is claimed is: 1. A locking system comprising: a handle having a first thread and a first locking member; and an implement having a second thread and a second locking member, wherein said first and second threads are threadably engaged so that said first and second locking members selectively engage one another to lock said handle to said implement, wherein said first locking member comprises a locking arm and said second locking member comprises at least one locking tooth. 2. A locking system comprising: a handle having a first thread and a first locking member: and an implement having a second thread and a second locking member, wherein said first and second threads are threadably engaged so that said first and second locking members selectively engage one another to lock said handle to said implement, wherein said first locking member comprises at least one locking tooth and said second locking member comprises a locking arm. 3. The locking system of claim 1 or 2, wherein said first thread is on an exterior surface or an interior surface of said handle. 4. The locking system of claim 1 or 2, wherein said second thread is on an exterior surface or an interior surface of said implement. 5. The locking system of claim 1 or 2, wherein said at least one locking tooth comprises a plurality of locking teeth. 6. A locking system comprising: a handle having a first thread and a locking arm; and an implement having a second thread and a locking tooth, said first and second threads being threadably engageable with one another upon rotation in a first direction and threadably disengageable with one another upon rotation in a second direction, said second direction being opposite of said first direction, wherein said locking arm moves from a first position to a second position during rotation in said first direction, said locking arm elastically returning to said first position upon engagement of said first and second threads to a predetermined point, said locking tooth and said locking arm engaging one another to prevent rotation in said second direction beyond said predetermined point when said locking arm is in said first position. 7. The system of claim 6, wherein said locking arm moves about a pivot axis during movement between said first and second positions. 8. The system of claim 7, wherein said handle has a longitudinal axis, and wherein said pivot axis is parallel to said longitudinal axis. 9. The system of claim 7, wherein said locking tooth has a cam surface for moving said locking arm from said first position to said second position during rotation in said first direction. 10. The system of claim 6, wherein said locking arm has a release button for moving said locking arm from said first position to said second position upon application of a releasing force on said button. 11. A locking system comprising: a handle having a first thread and a locking tooth; and an implement having a second thread and a locking arm, said first and second threads being threadably engageable with one another upon rotation in a first direction and threadably disengageable with one another upon rotation in a second direction, said second direction being opposite of said first direction, wherein said locking arm moves from a first position to a second position during rotation in said first direction, said locking arm elastically returning to said first position upon engagement of said first and second threads to a predetermined point, said locking tooth and said locking arm engaging one another to prevent rotation in said second direction beyond said predetermined point when said locking arm is in said first position. 12. The system of claim 11, wherein said locking arm moves about a pivot axis during movement between said first and second positions. 13. The system of claim 12, wherein said handle has a longitudinal axis, and wherein said pivot axis is parallel to said longitudinal axis. 14. A locking system comprising: a handle having a longitudinal axis and a first thread; an implement having a second thread, said second thread being engageable with said first thread upon rotation about said longitudinal axis in a first direction and disengageable with said first thread upon rotation about said longitudinal axis in a second direction, said second direction being opposite of said first direction; a first locking member defined on a respective one of said handle and said implement, said first locking member comprising locking arm defining a first locking surface; and a second locking member defined on a respective other of said handle and said implement, said second locking member comprising a locking tooth defining a second locking surface and a cam surface, wherein said locking arm is normally biased to a first position and is configured to flex to a second position about a pivot axis, said pivot axis being generally parallel to said longitudinal axis, wherein said cam surface is configured to bias said locking arm from said first position to said second position during rotation in said first direction, and wherein said locking arm is configured to elastically return to said first position upon rotation of said first and second threads to a predetermined point so that said first and second locking surfaces abut one another to prevent rotation in said second direction.
