ABSTRACT:
An anchoring device includes a cam rod having a pair of dual-spiral grooves thereon which are orthogonal to each other. The cam rod is provided with a pedal. A direction-switching device is enveloped onto the cam rod. An anchoring root is releasably engaged to the lower portion of the direction-switching device. The direction-switching device includes a driving wedge which is engaged with a socket of the anchoring root. The anchoring root can be engaged or disengaged with the direction-switching device. When the pedal is depressed, the direction-switching device can be driven by the spiral grooves of the cam rod. The anchoring root that is attached to the bottom of the direction-switching device is also rotated. The anchoring root is then screwed into the ground. After the anchoring root is positioned, the cam rod and the direction-switching device can be removed therefrom and a pole can be inserted into a pilot hole within the anchoring root.
