Abstract
A cutting device, including a frame, a cutting blade, which is fastened to the frame for pivoting about a first pivot axis, and a reduction transmission, which converts each forward pivoting movement of a plurality of successively performed forward pivoting movements and backward pivoting movements of a drive arm into a cutting pivoting movement of the cutting blade. A cutting-blade back-pivoting apparatus is provided, by which the cutting blade can be pivoted back from a pivoting end position to an initial position. The back-pivoting apparatus has, in particular, a tension element, which acts on the cutting blade in such a way that a clearance is formed.
Claims11
A cutting device, comprising:
- a frame;
- a cutting blade fastened to the frame so as to be pivotable about a first pivot axis;
- a reduction gear that converts forward pivoting movement of several successively performed forward and backward pivoting movements of a drive arm into a cutting pivoting movement of the cutting blade by a blocking element that is displaceable between a force transmission position at a drive flank and a release position, wherein the cutting blade is pivotable from an initial position into a cutting end position;
- and a cutting blade backward pivoting means for bringing the cutting blade back into the initial position, wherein the cutting blade backward pivoting means includes a coupling member fastened to the blocking element, the coupling member couples the drive arm to the cutting blade so that the cutting blade can be brought back into the initial position by a backward pivoting movement of the drive arm, wherein the blocking element is displaceable in an elongated hole in the drive arm and couples the drive arm during forward pivoting movements to a first wheel of the reduction gear in a force transmission position.
