发明名称 Ground plugging device
摘要 A lightweight, portable device for use in removing plugs of earth from the ground and particularly useful in connection with metal detecting. A hollow cylindrical body open at the top and bottom has sharpened teeth on its lower edge and a blunt upper edge against which the foot may be pressed to drive the body into the ground. A bail is pivotally attached to the body to facilitate its raising from the ground with simultaneous twisting. The bail may be pivoted to a lowered or retracted position wherein it is below the blunt upper edge of the body in order to completely expose the same for receipt of the foot.
