发明名称 Handheld power tool, in particular a power drill or screwdriver
摘要 A handheld power tool has a tool holder for holding a tool, and a grip housing for holding and guiding the handheld power tool. A relative motion of the tool holder and the grip housing can be transmitted as a switching motion to a microswitch, which switches a drive unit on and off. The tool holder and the grip housing can be moved relative to one another in a direction of rotation, and the switching motion thus comprises a rotary motion of the grip housing.

主权项 1. A handheld power tool, comprising: a tool holder configured to hold a tool; a grip housing configured to hold and guide the handheld power tool; a drive unit providing a driving motion to the tool holder; at least one microswitch operable to switch the drive unit off or on; and an actuating element configured to act on the microswitch, wherein a relative motion of the tool holder and the grip housing is configured to be transmitted as a switching motion to the at least one microswitch so as to switch the drive unit either on or off, wherein the tool holder and the grip housing are configured to be moved relative to one another in a direction of rotation about and axially along a longitudinal axis of the grip housing, and wherein the switching motion comprises a rotational motion of the grip housing about the longitudinal axis followed by an axial motion of the grip housing relative to the tool holder to thereby move the actuating element and microswitch relative to each other so that the actuating element acts on the at least one microswitch.
