Apparatus for applying leverage force to a hand drill
Abstract:
An apparatus for applying a leverage force to a hand drill has a rigid elongated support having a first end and a second end. A travel member is movable axially along the support with a friction lock for locking the travel member to the support in a selected axial position. A lever is pivotally attached to the travel member. The lever has an engagement surface for engaging a spine of a hand drill, whereby a force is exerted upon the hand drill by means of the lever. A stop is positioned at the second end of the support to prevent axial movement of the support when a force is exerted by the lever.
