  • Such a clamping device is sufficient for the described applications for clamping a tool.
  • the displacement device is designed such that an automatic secure clamping of the tool relative to the work spindle is ensured as soon as the tensioning lever is pivoted out of the release position. This forces occur, which cause the clamping lever abruptly goes into the clamping position. This quick turnover of the clamping lever affects the operating comfort.
  • the present invention seeks to provide a power tool of the type mentioned, with easy handling, reliable attachment of the tool, which further allows easy replacement of the tool.
  • the transition of the tensioning lever from the release position to the tensioning position can be influenced, in order to avoid a quick turning over of the tensioning lever. In this way, the handling is simplified, while the reliability of the attachment of the tool is maintained. A simple change of the tool is still possible.
  • the clamping position is the position in which the displacement device and the fastening element are arranged such that the tool is securely clamped against the work spindle.
  • the inhibiting device has at least one elastic restraining element and a counter contour which is movable relative thereto.
  • the force required to inhibit the pivoting movement of the tensioning lever can be applied in a controlled manner by simple geometrical configuration of the mating contour as a function of the respective relative position to the inhibiting element.
  • the abrupt transition of the clamping lever between release and clamping position is prevented.
  • the change of the tool is simplified.
  • the mating contour is formed in a pivoting range of the clamping lever between release position and clamping position for non-positive cooperation with the inhibiting element.
  • the mating contour in the clamping position of the clamping lever on a detent position for the inhibitor is provided.
  • the clamping position is additionally secured by the inhibiting element.
  • the inhibiting element is designed as a metal spring.
  • the inhibiting device may have as an inhibiting element a leaf spring made of flat material or a bending or torsion spring made of round material.
  • the counter contour is arranged on the clamping lever and the inhibiting element on the housing.

  • the elements of the inhibiting device can be covered and protected in the release position or the clamping position of the clamping lever.
  • the mating contour is arranged on a side surface of the clamping lever.
  • the inhibiting element is arranged on the clamping lever and the mating contour on the housing.
  • the mating contour is mounted directly on the housing in the manufacture of the housing.
  • the structure of the hand tool can be simplified.
  • the inhibiting element is arranged on the pivot axis.
  • the inhibiting element can be mounted on the pivot axis and secured axially. It may have additional elements for attaching the hemmelement be waived. As a result, a cost-effective, further simplified construction of the hand tool can be made possible.
