发明名称 Garden hand tool
摘要 A garden hand tool having a tubular outer member terminating at its bottom end in an elliptically shaped peripheral edge with such end being open, a plunger reciprocally mounted in the tubular member and a spring that resiliently biases the plunger upwardly in a direction away from the elliptically shaped open bottom end. The elliptically shaped peripheral edge is preferably in a plane disposed at an angle in a range of 15 DEG to 22 DEG +E,fra 1/2+EE to the longitudinal axis of the tubular member so as to be readily forced by hand into the earth to remove a weed or plant. The plunger projects upwardly beyond the upper end of the tubular outer member providing a portion that can be readily grasped to push the plunger downwardly to remove any earth associated with the plant that might be stuck in the bottom end of the outer tubular member.
