ABSTRACT:
A modular tool system includes a tool head, a handle, and an intermediate piece disposed therebetween. The handle includes a first pin for coupling the handle to the intermediate piece and the intermediate piece includes a second pin for coupling the intermediate piece to the tool head. The first and second pins each include a splined portion for engaging splined orifices in the handle and intermediate pieces, respectively, and a shank for removably engaging shank-receiving orifices in the intermediate piece and the tool head, respectively. When the shanks are engaged with their respective shank-receiving orifices, the handle can be moved along the first pin to selectively lock the handle to the intermediate piece and the intermediate piece can be moved along the second pin to selectively lock the intermediate piece to the tool head. The handle can also be moved along the first pin to selectively unlock the handle for rotational movement about the pin relative to the intermediate piece and the intermediate piece can be moved along the second pin to unlock the intermediate piece for rotational movement about the pin relative to the to the tool head. If desired, the intermediate piece can be removed and the handle can be coupled directly to the tool head by inserting the first pin into the tool head's shank-receiving orifice.
