Abstract
A cutting tool (1), and a method of exchanging an interchangeable blade as well as a cutting tool housing, in particular for severing flat and/or strand-form materials. The cutting tool (1) includes a housing (2), at least one interchangeable blade (8) arranged at a holding portion (6) of the housing (2), and a locking member (40) arranged movably on the housing (2) for locking the blade (8) to the housing (2). The housing (2) has first positively locking elements (23, 24, 26, 28) and the locking member (40) has second positively locking elements (42) which jointly lock the blade (8) in a given position to the housing (2).
Claims8
A cutting tool comprising:
- a housing including a holding portion, a gripping portion, and a plurality of positive-locking elements at the holding portion;
- a rotational lever mounted pivotably to the housing;
- a blade arranged at the holding portion of the housing, the blade including a cutting edge and a plurality of positive-locking elements;
- and
- a locking member coupled with the rotational lever and configured to lock the blade to the housing, the locking member reciprocatingly movable between a first position in which the blade is locked and a second position in which the blade is released, and the locking member having a positive-locking element configured to cooperate with the positive-locking elements of the housing to lock the blade in a given position to the housing,
- wherein the positive-locking elements of the blade further cooperate with the positive-locking elements of the housing and the locking member in such a way that substantially no moments are introduced into the rotational lever by virtue of cutting reaction force, wherein the cutting edge of the blade faces rearwardly and towards the gripping portion of the housing, and wherein the holding portion includes one side where the positive-locking elements of the holding portion are provided and another side located in opposite relationship to the one side, the another side being where the cutting edge of the blade is located.
