Tool reception device for electric handtool with blocking device preventing rotation of tool spindle during operation of rotary chuck for clamping or release of tool

摘要

The tool reception device (10) allows a disc-shaped tool (12), e.g. a grinding disc or a circular saw blade, to the tool spindle (8), with a rotary chuck (18) for clamping and release of the tool operated via a rotary tool (20) of the handtool (2), a blocking device (37) preventing rotation of the tool spindle when a torque is exerted on the rotary chuck for releasing or clamping the tool. The blocking device has a blocking element (30) supported in the tool spindle and displaced axially between the blocking position and the released position.
