Tool device

A tool device with a tool for processing a workpiece located in a working area, comprising:

• a tool braking device for braking a tool rotary movement of the tool, and
• a multi-joint arrangement by means of which the tool can be pivoted selectively in a feed direction into the working area or in a removal direction out of the working area,
• wherein the multi-joint arrangement is designed to, while maintaining the pivotability of the tool, absorb and/or redirect forces occurring during braking of the tool rotary movement, so that the tool is not pivoted in the feed direction by the forces occurring during braking of the tool rotary movement or is pivoted in the removal direction by the forces occurring during braking of the tool rotary movement,
• wherein the multi-joint arrangement comprises a base section, a main swing arm pivotally mounted on the base section via a base section joint, a side swing arm pivotally mounted to the main swing arm via a main swing arm joint, and a secondary swing arm pivotally mounted to the side swing arm via a side swing arm joint and pivotally mounted to the base section via a secondary swing arm joint,
• wherein over at least 80% of the pivot range of the multi-joint arrangement, the main swing arm axis and the secondary swing arm axis converge at an axis angle on that side of the base section on which the tool is arranged.

A tool device with a tool for processing a workpiece located in a working area, comprising:

• a tool braking device for braking a tool rotary movement of the tool, and
• a multi-joint arrangement by means of which the tool can be pivoted selectively in a feed direction into the working area or in a removal direction out of the working area, wherein
• the multi-joint arrangement is designed to, while maintaining the pivotability of the tool, absorb and/or redirect forces occurring during braking of the tool rotary movement, so that the tool is not pivoted in the feed direction by the forces occurring during braking of the tool rotary movement or is pivoted in the removal direction by the forces occurring during braking of the tool rotary movement,
• wherein the tool device further comprises a drive unit for setting the tool in the tool rotary movement, the tool device being adapted to maintain a delay time between a triggering of the tool braking device and a switching off of the drive unit and, during the delay time, to redirect a drive force, which is provided by the drive unit and acts on the tool, by means of the multi-joint arrangement, so that the tool is pivoted in the removal direction.

• wherein the multi-joint arrangement comprises a base section, a main swing arm pivotally mounted on the base section via a base section joint, a side swing arm pivotally mounted to the main swing arm via a main swing arm joint, and a secondary swing arm pivotally mounted to the side swing arm via a side swing arm joint and pivotally mounted to the base section via a secondary swing arm joint,
• wherein the tool device further comprises a handle arranged on the main swing arm, wherein the handle is for manually effecting a pivoting of the tool by means of the multi-joint arrangement.
