Abstract
A tool includes a handle having a bore for slidably receiving a stop and a link. The link has one end pivotally coupled to the stop for allowing the link to be rotated relative to the stop when the link is extended outward of the handle. A driving stem is pivotally coupled to the link for allowing the driving stem to be rotated relative to the link when the link is extended outward of the handle. A ratchet mechanism is disposed in the handle and is selectively engaged with the stop for controlling the driving direction of the driving stem.

A tool comprising:
- a) a handle including a bore formed therein and including a first end and a second end;
- b) a stop slidably received in said bore of said handle;
- c) a link slidably received in said bore of said handle and extendible outward of said bore of said handle, said link including a first end rotatable coupled to said stop, said link being aligned with said stop when said link and said stop are received in said bore of said handle, and said link being rotatable relative to said stop when said link is extended outward of said handle, said link including a second end;
- and
- d) a driving stem including a first end rotatable coupled to said second end of said link and rotatable relative to said link when said second end of said link is extended outward of said handle, said driving stem being aligned with said link when said stop and said link and said first end of said driving stem are received in said bore of said handle, and for allowing said driving stem to be solidly driven by said handle when said first end of said driving stem is received in said bore of said handle.
