The handheld power tool has a tool socket to hold a chiseling tool on a working axis and a striking mechanism that acts upon the tool in the striking direction. The striking mechanism is arranged in a machine housing. A handle is oriented along a handle axis that is perpendicular to the working axis and that is installed on the machine housing by three suspension assemblies. The second suspension assembly has a lever arm that runs along the handle axis. The first end of the lever arm is attached to a machine housing and to a handle. A guide is attached to the other machine housing and handle. The second end of the lever arm in the guide can be forcibly deflected against a spring along a trajectory that is slanted or perpendicular to the working axis.

Handheld power tool

A hand machine tool includes a tool retainer that retains a tool, a motor that drives the tool retainer in a rotary motion, and a torque-controlled sliding clutch that is connected in a drivetrain between the motor and the tool retainer. The sliding clutch includes a first clutch disk, a second clutch disk, a spring and a controlling unit which can be activated manually. The second clutch disk is arranged displaceably alongside an axis limited by a stop in the direction toward the first clutch disk. Force is applied to the second clutch disk by the spring alongside the axis in the direction toward the first clutch disk. The manually activated controlling unit variably sets an axial distance between the first clutch disk and the stop, with which an engagement depth of the first clutch disk with the second clutch disk can be defined.

Hand machine tool

A hand-operated jigsaw is disclosed. The reciprocating drive mechanism has a reciprocating body which can be put into a reciprocating motion along an axis via an eccentric of an eccentric wheel that can be set in motion by the motor. The eccentric wheel is arranged on a pivot bearing axis. The reciprocating drive mechanism has an additional mass with a mass center of gravity to minimize vibrations. The additional mass is arranged in a rotationally fixed manner with the eccentric wheel on the pivot bearing axis. An eccentric axis of the eccentric lies on a first radial of the pivot bearing axis, which is offset from a second radial in the operating direction of rotation of the eccentric wheel at an angle of between 190&#xb0; and 270&#xb0;, which second radial lies between the mass center of gravity of the additional mass and the pivot bearing axis.

Hand-operated jigsaw

A hand-held power tool () has a base housing () in which there is provided an operational unit () movable in a reciprocating manner along a operational axis (A) defining a first spatial axis (z) and spaced from a center of gravity (SP) of the hand-held power tool () in direction of a second spatial axis (y) which is perpendicular to the first spatial axis, (z), and further has a cover housing () which is held on the base housing () by decoupling elements and is fixedly connected to a main handle () and to side-handle connection element (), with the decoupling elements having, in a projection perpendicular to a plane (Eyz) defined by the first spatial axis (z) and the second spatial axis (y), a first support device () which is located adjacent to the center of gravity and which holds the cover housing () on the base housing () so as to be displaceable along and pivotal in direction of the first spatial axis (z).

Hand-held power tool

A hand-held power tool includes a main handle, a percussion mechanism striking along a percussion axis, a counter mass displaceable along an oscillation axis which is inclined to the percussion axis and biasing elements for preloading the counter mass to a rest position on the oscillation axis. The counter mass is arranged such that the rest position is closer to the main handle than the center of gravity is to the main handle.
