Claims

[Claims for Utility Model Registration] 1. Consisting of a pipe-like body and a sphere, the body has a spiral groove in the upper part into which a bolt can be screwed into the inner tube, and a vertically extending outer part in the lower part of the body. An anchor characterized in that several slits are bored from the tube to the inner tube, and the inner tube is provided with a small hollow space having a smaller diameter than the sphere. 2. The anchor according to claim 1 of the utility model registration claim, characterized in that the outer tube below the main body is provided with grooves carved upward to prevent it from coming off. 3. The anchor according to claim 1 of the utility model registration, characterized in that a large ball cavity in which a sphere can be mounted is attached above the small ball cavity in the inner tube of the main body. 4 Between the large ball cavity and the small ball cavity in the inner tube of the main body,
The anchor according to claim 3 of the utility model registration, characterized in that the anchor is provided with an intermediate conduit portion that is constricted downward.
