Abstract:
A pinching tube cutting device for transversely cutting an elongated plastic tube having a predetermined radius and having a longitudinal axis through a centerpoint comprising:two handles connected one to the other in a pivoting movement around a pivot point, and each handle having a outer peripheral edge, a center axis, and a head which is extended by an elongated portion forming a gripping portion, the head of the first handle having a cutting blade and the head of the second handle having a hollow seat having an arcuate surface with another predetermined radius essentially equal to the predetermined radius of the tube for receiving the tube to be cut, said pivot point positioned offset relative to the first and second gripping portions so that the pivot point is proximate to the outer peripheral edge of the first handle and spaced from the cutting blade and hollow seat wherein said pivot point is positioned closer to the center axis and gripping portion of the first handle than the center axis and gripping portion of the second handle for providing a large area of rotation for the blade, and the blade movable to rotate in a cutting direction and a reverse direction in response to the pivoting movement of the two handles, the blade having an outer sharp edge and an inner sharp edge forming a point of the blade therebetween, the inner sharp edge positioned closer to the pivot point than the outer sharp edge, and the point of the blade positioned for intersecting an imaginary first straight line defined as passing between the pivot point and the centerpoint for the radius of the seat, said point of the blade intersecting the imaginary first straight line at a position point spaced from the centerpoint and between the pivot point and centerpoint when said blade rotating in the cutting direction for preventing any flattening of the tube.
