ABSTRACT
A specific example is a lever device that can be attached to a drill for use in constricted areas where it is not possible to bring into play large muscles or body weight as normal. The butt of the device is placed against some adjacent support. Squeezing the lever extend. it, pushing the drill bit down. Enterprising workers in these situations sometimes use a plain stick to jam against the adjacent support to gain leverage. but the device provides a more convenient and polished approach for the same result.
