Zusammenfassung:	The utility model relates to an expansion bolt particularly adequate to be used for mounting objects, composed of a cone nut, an expansion sleeve and a hexagon-head bolt. A flange is arranged on the cone nut and is embedded inside a stripping edge of the expansion sleeve. The stripping edge of the expansion sleeve is tightly clamped inside a dietella wall. Solving the defect that the existing expansion screw-rod is easy to slip and can be taken out only when the wall is smashed, the utility model has the advantages of simple structure and no specific requirement for the processing technology, and can effectively prevent from slipping as well as can be taken out from the wall hole.
