Abstract
A cutting tool includes a housing having a blade opening and a biasing member having a securing portion, an engaging portion, and a semi-circular body portion in between the securing portion and the engaging portion. The securing portion secures the biasing member to the housing within the housing and the engaging portion extends away from the body portion. An annular blade is biased by the engaging portion towards the opening and against the housing, with the blade at least partially extending through the blade opening.
Claims16
A cutting tool comprising:
- a housing having a blade opening;
- an annular blade at least partially extending through the blade opening;
- a biasing member including a securing portion, an engaging portion, and a semi-circular body portion in between the securing portion and the engaging portion, the securing portion securing the biasing member to the housing within the housing, the semi-circular body portion defining a plane that bisects the entire length of the semi-circular portion, the engaging portion biasing the blade perpendicularly with respect to the plane, and the engaging portion extending away from the body portion;
- and
- an arcuate first rail and an arcuate second rail arranged within the housing, and wherein the blade comprises an annular cutting portion having a first side and a second side that is opposite the first side, a first shoulder on the first side and facing the first rail and a second shoulder on the second side and facing the second rail, a first axle extending outwardly from the first shoulder and a second axle extending outwardly from the second shoulder, and wherein the biasing member biases the blade such that the first axle is engaged against the first rail and the housing, and the second axle is engaged against the second rail and the housing.
