Extractor tool for expansion anchor

摘要

The tool (10) has a coupling element (12), which is positively connected to the expansion sleeve (32) of the anchor. The coupling element supports itself via an internal counter holder (14) on the expander body (28), and is moveable in axial direction against the counter holder. The coupling element is sleeve-shaped, and also has one part (20) of a bayonet closure (20,36). The counter holder is formed by a bolt, and holder and coupling element have a screw connection (16), for relative axial movement. A coupling unit (36) on the expansion sleeve is positively connected to the coupling element of the tool. The unit forms the second part of the bayonet closure.
