ABSTRACT:
A nail remover according to the present invention includes a tool head having a guide bore extending linearly through the head in a longitudinal direction, a push-rod slidably mounted in the guide bore of the head between a retracted position at which a free end of the push-rod is located in the guide bore and an extended position at which the free end of the push-rod protrudes from the guide bore, a driving device for advancing the push-rod from the retracted position to the extended position, and an actuator for activating the driving device. At least a portion of the peripheral wall defining an outlet of the guide bore is tapered toward an outboard edge of the wall so as to make it easy to introduce a nail into the guide bore. In operation, the guide bore receives the portion of a nail protruding from a plate such as a piece of plywood. Then the nail is straightened by aligning the guide bore with the axis of the nail and, thereafter, the push-rod is driven towards the extended position so as to drive the nail out of the plate.
