1. Screw-in aid for screwing a long screw in a defined screw-in angle into an underground having at least one ground engaging portion for placing on the underground and at least one screw placing portion for placing the screw therein,
wherein the screw-in angle is formed between the screw placing portion and the ground engaging portion,
wherein at the screw placing portion, a screw holder is arranged which forms a screwing channel for the screw, to guide the screw when screwing into the underground;
wherein the screw-in aid forms a closed polygon;
wherein the screw holder encompasses, at the at least one screw placing portion, a longitudinally displaceable spring clip comprising a substantially U-shaped cross-section for securing the screw holder to the screw-in aid, wherein a covering plate is pivotably mounted on the clip, such that the covering plate is configured to be pivoted away from the screw placing portion, to enable in this open state the placement of a screw at the screw placing portion, or pivoted toward the screw placing portion in a closed state, when the covering plate abuts against the screw placing portion, to form a closed screwing channel between the screw placing portion and the covering plate.
