ABSTRACT:
A ground-anchoring device for anchoring a pole in the ground, comprises a post formed with spiral threads at one end for threading into the ground; a socket at the opposite end for receiving an end of the pole to be anchored in the ground; and a pair of arms pivotally mounted at the opposite end of the post from a horizontal position facilitating the rotation of the post to thread it into the ground, or to a vertical position. The pair of arms include clamping elements movable to a releasing position with respect to the socket when the arms are in their horizontal positions, or to a clamping position when the arms are in their vertical positions to clamp the pole within the socket.
