发明名称 Staple and tack extractor
摘要 A hand tool having utility in the extraction of staples, tacks and nails. A thirty degree bend is formed near the distal end of an elongate, rigid shank. The shank widens laterally outwardly distal to the bend, forming a pair of laterally extending wing members that exhibit bilateral symmetry. The shank returns to its original breadth at the distal end of the wings and four parallel claw members extend therefrom. The four claw members are separated by horizontal and vertical slots that divide the claws into a first, upper pair and a second lower pair. The lower pair of claws has a greater longitudinal extent than the upper pair and have a feather edge to facilitate sliding of said lower pair under the crown of a staple. The collective breadth of the lower pair of claws is slightly less than the breadth of a staple so that the crown of the staple is supported at its opposite ends during the extraction procedure.
