ABSTRACT:
This invention includes and is directed toward and to a tool handle exemplified in two embodiments. A variety of tool blades can safely be inserted in one end of the tool handle allowing length and leverage heretofore impossible. This feature allows a person to carry the wrench in a closed tool box since the parts disassemble for storage. A ratchet can be inserted in the opposite end of said handle to provide the user with much greater torque to assist in many difficult jobs. The handle has a through passageway substantially along its longitudinal axis. In the passageway there is formed at least one flat surface with the passageway sized to snugly retain the shank of a tool. The tool handle includes a body provided with a trigger having two legs, one of which has an aperture which is moved in way of the passageway to allow the shank of the tool to be moved therein and therethrough. The trigger is biased outwardly to bring a portion of the trigger in way of one of a series of slots or detents formed in the tool shank and locking said shank in the selected position. The trigger is limited in its outward movement and against loss by a retaining pin secured in the handle and arranged to engage the other leg of the trigger and limit the outer travel of the trigger.
