ABSTRACT:
A pipe cutting device comprises a housing to which a tool case is attached to be rotatable, and by rotating manually or electrically the tool case so that the openings of the tool case and a follow-up gear disposed in the tool case substantially align with the opening provided for the housing, is formed a pipe inserting passage for inserting a pipe from the opening side of the openings of these members towards the central portion of the tool case. Two driving gears meshed with the follow-up gear are driven by a motor through the power transmission mechanism to rotate the tool case. The rotation of the tool case drives the cam roller to operate the cam plate, and the clutch arm is rotated by predetermined angles by every one rotation of the tool case thereby to minutely rotate the eccentric cam by predetermined angles through the one-way clutch. The rotation of the eccentric cam rotates the lever mechanism which is operatively connected to the cutter. Thus, the pipe squeezed between the cutter and the support rollers located in the tool case is cut in minutely by every one rotation of the tool case.
