Description

FIELD OF THE INVENTION

The present invention relates to a tool having dual flex heads. More particularly, the invention relates to a tool having a flex head having a ratchet head and a flex head having a bit driver.

BACKGROUND OF THE INVENTION

Ratchet wrenches and bit drivers are known in the art. Similarly, tools having flex heads are known in the art. However, many of these tools have shortcomings including (1) they are not versatile in use; (2) the tools having a ratchet and bit driver on the back side thereof are awkward and cumbersome to use; (3) many of the tools are short and do not provide sufficient leverage; (4) the tools cannot reach “tight” spots; and (5) similar problems.

Accordingly, the known tools while useful for certain applications have various shortcomings. These and other shortcomings of such tools are addressed by the present invention.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide a tool offering versatility by having a ratchet at one end having a flex head and a bit driver at the other end of the tool having a flex head.

Another primary object of the present invention is having a tool having a ratchet at one end of the tool having a flex head and a bit driver at the other end of the tool having a flex head wherein there is a locking mechanism for one or both of the flex heads.

Another primary object of the invention is providing a tool as set forth above having a ratchet including a specific reversing mechanism as disclosed herein.

Another primary object of the invention is providing a tool having a ¼ inch ratchet at one end to accept ¼ inch drive sockets, extensions, etc. and a ¼ inch bit driver at the opposite end which accepts ¼ inch bits and has a magnet to hold the bits in place. Each of the ends have a flex head for adjusting the application angle. The flex heads provide for 180° rotation about the handle. Additionally, the tool may include a locking mechanism on one or both of the ends of the tool for locking the flex heads into the specific desired application angle.

These primary and other objects of the invention will be apparent from the following description of the preferred embodiments of the invention and from the accompanying drawings.
