Head-shaking fork door-shield with fork entry facing upwards
A head-shaking fork door-shield with a fork entry facing upwards is disclosed. The door-shield is especially placed underneath an opened door leaf and can be used after position of the door-shield is adjusted. The door-shield is composed of a head-shaking fork, a door-shield seat and a fork holder joint. The head-shaking fork is provided with two parts, namely the fork entry and a fork handle. The door-shield seat is provided with two parts, namely a seat and a seat pillar. The fork holder joint is Z-shaped. One end of the fork holder joint is a holder joint capable of being inserted into a seat pillar cavity with an upturned opening on the seat pillar, and the other end of the fork holder joint is a fork joint which can extend into the center between upper and lower layers of the fork handle and is provided with a stationary shaft capable of being sleeved with a fork handle shaft hole. When the door leaf is opened at a desirable position to stop the door leaf and the door-shield is placed between the lower edge of the door leaf and the ground, the door leaf is blocked. Tension of closing the door leaf makes the whole head-shaking fork to move with the stationary shaft as the center of a circle, and then the door leaf can be closed.
