Beschreibung
Zusammenfassung:	The invention aims to supply perfectly- operated cone plug-in board, screw -connected structure which uses screw of cone plug-in board with female thread , formative drill head which is used to process inserted holl of cone plug-in board and hummer to hammer in the cone plug-in board. The cone plug-in board is designed tapered part, flange part and female thread, the surface outside of the tapered part is cone-stage shaped, the flange part is formed at the export end point of the tapered part protruding oppositely to the tapered part, and owns flat that plumbs to the tapered part in the axes direction, the female thread is the extension part that extends in the axes direction. In the holl of processing the tapered part and stepped part at the same time, hammer in the cone plug-in board and form the jointed component of the screw joint structure.
