Claims14
A grinder, comprising:
- a grinding spindle configured for attaching a grinding tool;
- a housing having a first region facing towards the grinding spindle and having a second region faces away from said grinding spindle;
- a dust extraction duct;
- a first releasable connection between said housing and said dust extraction part allowing securing of said dust extraction part to said housing when being in a working position and allowing removal of said dust extraction part when being in an assembly position;
- and
- a second releasable connection cooperating with said first releasable connection;
- wherein said first releasable connection comprises a pivot joint;
- and wherein said second releasable connection is configured for latching said dust extraction duct to said housing when being in said working position;
- wherein said first releasable connection comprises a substantially cylindrical recess, into which a flat pivot can be inserted, said recess comprising a lateral insertion slot cooperating with said flat pivot so as to allow inserting of said pivot through said insertion slot into said recess when being in said assembly position, and to allow pivoting said flat pivot within said recess for swivelling said dust extraction duct from said assembly position into said working position.
