  • Patent number: 8650761
    Abstract: A fastening apparatus for a limit stop element of an electric hand tool, in particular a hand circular saw, is disclosed. The fastening apparatus includes a guide, into which the limit stop element can be inserted and along which it can be displaced, and a locking mechanism, which can lock the limit stop element in the displacement direction. The locking mechanism has a spring element, which, in its locked position, clamps the limit stop element with a clamping force directed against the limit stop element and, in a released position, permits a displacement of the limit stop element.

  • Patent number: 8640347
    Abstract: 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° and 270°, which second radial lies between the mass center of gravity of the additional mass and the pivot bearing axis.
