发明名称 Post hole digger
摘要 An improved post hole digger which comprises a plurality of elongated arm members having a proximal end and a distal end and an inner surface and an outer surface. A sharpened shovel blade is secured to the distal end of each of the elongated arm members, and a hinge pivotally secures the sharpened shovel blades to each other. A detachable top plate assembly is affixed to the proximal end of the elongated arm members and allows a user to strike the improved post hole digger with a weighted object such as a sledge hammer in order to drive the sharpened shovel blades into the ground. A handle bar is secured perpendicular to the outer surface of each elongated arm member at the proximal end of the elongated arm member, and a foot peg is secured perpendicular to the outer surface of each elongated arm member at the distal end, thus allowing a user to alternatively drive the sharpened shovel blades into the ground by holding the improved post hole digger by the handle bars so that the sharpened shovel blades point into the ground, and then jumping upon the foot pegs.
