发明名称 Gardening tool
摘要 A gardening tool includes a handle, a shaft and a pair of helical drill elements. The shaft extends from the handle longitudinally to a pointed shaft distal end. The pair of helical drill elements are spaced from and surround the shaft. The helical drill elements extend along the shaft and have free drill distal ends. The shaft distal end extends farther from the handle than does the drill distal ends. A debris-ejecting assembly includes a pusher slidable longitudinally along the shaft between the shaft and the drill elements. The ejecting assembly includes a spring arranged between a portion of the shaft and the pusher. The spring urges the pusher away from the shaft distal end toward the handle.
