FIELD: machine building.
SUBSTANCE: invention relates to hand-held machine components. Safety device to prevent inadvertent separation of the clamping element (12a) and/or the working tool (14a) of the spindle (16a) in the braking mode comprises at least one transmission unit (18a; 18b), comprising a first transmission element (26a, 26b), second transmission element (72a, 72b), movable relative to the first transmission element (26a, 26b), and a node (84a, 84b) change the motion for converting a mode of braking the first relative movement between the first transmission element (26a, 26b) and the second transmission element (72a, 72b) to the second relative movement. Safety device comprises the component compensating unbalance (20a; 20b) in order to reduce the transmission (18a; 18b) unbalance during manual operation of the machine. Unbalance compensating component (20a, 20b) includes at least one unbalance compensating element (22a, 22b; 24a, 24b) movably installed in the transmission element (26a, 26b) being a part of the transmission assembly (18a, 18b).
EFFECT: technical result consists in reduction of unbalance of the transmitting element during the hand-held machine operation.
