ABSTRACT:
The stand for a portable power drill has a base supporting an upright column on which a clamp is mounted for slideable movement to a desired height where it is fixed. A carriage is slideably mounted on the column with a bushing on each side of the clamp. A spring biases the carriage upwardly. A power drill is clamped on the carriage and the carriage can be moved downwardly relative to the clamp against the bias of the spring to feed the drill bit into the work. A lock plate having an aperture slightly larger than the diameter of the column fits over the column and is spring biased to tilt on a fulcrum on the underside of the clamp. When tilted, the aperture edges engage ("and bite") the column to support the carriage and drill. The plate has a pad which is depressed against the spring bias to release the plate so the clamp and carriage can be raised or lowered.
