ABSTRACT:
A wrench includes a wrench head mounted on an end of a handle. A handle of the wrench includes a fixed portion and a rotatable portion. Rotation of the rotatable portion of the handle causes movement of at least one contact surface of the wrench head. In one embodiment, rotation of the rotatable portion provides adjustment or movement of one of the jaws of the wrench head relative to another jaw of the wrench head. In another embodiment, rotation of the rotatable portion provides rotation of the wrench head. The rotatable portion of the handle is slidably mounted within the fixed portion of the handle, such that rotatable portion can be selectively extended to provide additional leverage on the wrench.
