Braking device for electrical tool

An electrical tool, comprising an electric motor;

• a shaft for transmitting torque to a working tool;
• and a braking device for braking the shaft and thereby the working tool, the braking device comprising a manually operated actuation member (1), a braking drum (4) secured on the shaft for joint rotation therewith and a braking member (5) secured on the actuation member for joint displacement therewith, the actuation member being linearly displaceable upon a biasing force of a return spring acting thereon for pressing the braking member against a circumferential surface of the braking drum for braking the shaft and thereby the working tool.

A braking device for an electrical tool including an electric motor and a shaft (3) for transmitting torque from the electric motor to a working tool, the braking device comprising an actuation member (1);

• a braking drum (4) secured on the shaft for joint rotation therewith;
• and a breaking member (5) secured on the actuation member (1) for joint displacement therewith, the actuation member (1) being linearly displaceable upon a biasing force of a return spring acting thereon for pressing the braking member against a circumferential surface of the braking drum for braking the shaft and thereby the working tool,
• wherein an operational direction of the braking member (5) is offset with respect to a feed direction (Z) of the actuation member (1) in a rotational direction (D) of the shaft (3) by an angle (α) that amounts to at most 90°, and wherein the actuation member (1) has a plurality of elongate slots (6) extending in the feed direction (Z) of the actuation member, and a corresponding plurality of bosses (7) engaging in respective elongate slots (6) for guiding the actuation member.
