An oscillating tool includes a housing, a motor housed in the housing and a clamp assembly operatively driven by the motor in an oscillating motion. The clamp assembly can hold an accessory such as a blade or sanding attachment, and the clamp assembly includes a first clamp and a second clamp. The oscillating tool also includes a clamp lever and an actuating lever. The clamp lever is operatively coupled to the first clamp to move the first clamp such that clamp assembly is moved from a closed position to an open position. The actuating lever is operatively coupled to the clamp lever to effect movement of the clamp lever, movement of the clamp lever causing the clamp assembly to move from the closed position to the open position.

A tool changing mechanism includes a tool base housing, a mandrel disposed therein and having a chamber and a keyway provided axially, and first and second linked units. A first shoulder portion is provided at an end of the keyway, and pulling jaws are disposed at the other end. The first linked unit has a first pulling rod, an end of which has an external thread, and the other end has a connecting portion driven by a pneumatic cylinder. The second linked unit has a second pulling rod, an end of which has an internal thread, and a pressing head is disposed at the other end. The second pulling rod has a sliding key located in the keyway. The first pulling rod is screwed into the second pulling rod, and the relative screwing rotation therebetween attains tool pulling for fixing or tool loosening for removing the cutting tool.

In a device, in particular machine, for producing Wiegand wire from a wire, in particular pulse wire, and a method for operating a device, the device having a first clamping chuck, a second clamping chuck, and a third clamping chuck, the wire being fed through each of the three clamping chucks, in particular so that the wire is able to be connected in a releasable and torsionally fixed manner to the three clamping chucks, in particular able to be connected to the three clamping chucks in a releasable, torsionally fixed and nonpositive manner. The clamping chucks are set apart from one another in the wire direction, and the second clamping chuck is situated between the first and the third clamping chuck in the wire direction. The second clamping chuck is rotatably mounted so that a torsion is able to be applied to a first wire section and the reverse torsion is able to be applied to a second wire section, the first wire section being situated between the first clamping chuck and the second clamping chuck, the second wire section being situated between the third clamping chuck and the second clamping chuck. The distance in the wire direction between the first and the second clamping chuck is controllable and/or regulatable with the aid of a first linear actuator, and the distance in the wire direction between the second and the third clamping chuck is controllable and/or regulatable with the aid of a second linear actuator.
