Abstract
A cutting tool includes a first and a second element having a handle in a first end and a cutting element in a second end. A spring element is arranged between the first and second element to move the handles away from each other, and an adjustment mechanism sets a maximum opening angle for the handles. The adjustment mechanism includes a groove in a side surface of the first element, an adjustment ring is arranged to a side surface of the second element, and a shaft which is rotatably arranged to protrude through a hole in the second element, a first end of the shaft engaging the engagement surface of the adjustment ring and a second end of the shaft having an eccentric part protruding into the groove in the first element.
Claims5
A cutting tool, comprising
- a first and a second element having a handle in a first end and a cutting element in a second end, the first and the second element being rotatably joined by a pivot such that when the handles are moved towards each other, also the cutting elements move towards each other,
- a spring element arranged between the first and second element to move the handles away from each other, and
- an adjustment mechanism for setting a maximum opening angle for the handles, at which opening angle the spring element cannot move the handles further away from each other, the adjustment mechanism comprising:
- a groove in a side surface of the first element which faces the second element, the groove having a stop edge,
- an adjustment ring arranged to a side surface of the second element which faces away from the first element, the adjustment ring having an engagement surface and being rotatable around an axis of rotation of the pivot for allowing a user to set the maximum opening angle for the handles, and
- a shaft which is rotatably arranged to protrude through a hole in the second element, a first end of the shaft engaging the engagement surface of the adjustment ring for rotating the shaft around a longitudinal center axis of the shaft when the adjustment ring is rotated, a second end of the shaft having an eccentric part protruding into the groove in the first element such that the eccentric part comes into contact with the stop edge once the maximum opening angle for the handles is reached.
