摘要:
The invention is based on a dust suction adapter device comprising a base body unit (12) having a coupling point (14) for attachment to a hand-operated machine tool (16) and having at least one suction channel (18), and further comprising a suction head unit (20) displaceable on the base body unit (12). It is proposed that the dust suction adapter device is provided with at least one interface (22) for an external suction unit (24).
摘要:
The invention relates to a hand tool (1), particularly electric hand tool, having a drive (5), a tool shaft (3), a first overload clutch (14) and a transmission (6), which comprises a first and at least one second gear wheel unit (7, 8), said gear wheel units being operable alternatively to transmit torque. According to the invention, at least one second overload clutch (18) is provided and is permanently and exclusively operatively connected to the first gear wheel unit (7).

The invention relates to a hacksaw or jigsaw (10) comprising at least one housing (14), a tool area (16) for a linear and/or oscillating driven saw blade (18), a control (20) on the housing side for activating a working saw motion (24) by an operator, a drive unit (22) disposed in the housing (14) for generating the working saw motion (24) of the saw blade (18), an electronic unit (36) disposed in the housing (14) for applying at least control and/or feedback signals to the drive unit (22). The drive unit (22) comprises at least one excitation actuator (38) having a volume of active excitation material for generating a microwork motion (28) controlled or regulated by the electronic unit (36) during operation. According to the invention, the excitation actuator (38) can overlay the microwork motion (28) at least on the working saw motion (24) of the saw blade (18).

The invention relates to a hand-held tool (1), in particular an electric handheld tool, comprising a drive motor (4), a tool shaft (14) and a first overload clutch (19) for limiting the maximum torque acting on the tool shaft (14). According to the invention, it is provided that at least a second overload clutch (20) is provided.
摘要:
The invention relates to an electric hand-held power tool comprising a control and/or regulating device for an electric motor. According to the invention, said control and/or regulating device is associated with an electronic memory element for at least one operating state of the electric motor.
摘要:
A machine tool, for example a hand-held belt grinder, is subjected to high frequencies outside a working plane between an abrasive belt and a workpiece. In particular, the machine tool is subject to high frequencies in a free-running region of the belt, of an excitation actuator, in particular by a piezo element.
摘要:
A guide device for hand-held power tools has a guide part (3, 10) which can be placed onto the workpiece upper side (4) of the workpiece to be machined and on which a roller arrangement is held which rolls on the workpiece upper side and has at least one roller (8) which is mounted rotationally on the guide part.
