FIELD: machine building.
SUBSTANCE: invention relates to hand-held machine. Safety device of manual machine to prevent spontaneous separation of clamping element (12a; 12b; 12c) and/or working tool (14a, 14b, 14c) from spindle (16a; 16b; 16c) contains at least one transfer assembly (18a; 18b; 18c) and at least one cam mechanism (20a; 20b; 20 c), having at least one cam link (22a, 72a; 22b, 72b; 22c, 72c). Cam mechanism (20a; 20b; 20c) has at least one cam slot (24a, 74a; 24b, 74b; 24c, 74c), in which at least partially enters cam link (22a, 72a; 22b, 72b; 22c, 72c). Cam slot (24a, 74a; 24b, 74b; 24c, 74c) is made in the form of grooves.
EFFECT: technical result consists in improvement of reliability of safety device and safety of manual machine.
