Claims

[Scope of Claim for Utility Model Registration] (1) A pair of parallel lower support rollers that are pivotally supported on a machine stand and rotatably support the pipe to be cut, and an upper side that is pivotably supported on the machine stand so that it can freely move up and down. The opening/closing arm and the upper opening/closing arm are rotatably supported,
a pair of parallel upper press rollers that rotatably press the pipe to be cut between the lower support rollers; and a tightening means that tightens the upper press rollers in a direction for holding the pipe to be cut via the upper opening/closing arm. , a cutting operation lever whose base end is rotatably supported vertically on the machine base below the lower support roller; a rotary cutter rotatably supported on the cutting operation lever; and a cutting operation lever equipped with the cutting operation lever. a cutter driving means for rotationally driving the rotating cutter; an auxiliary roller lever rotatably supported near at least one of the lower support rollers; and a rotatably supported roller lever at a free end of the auxiliary roller lever. and an auxiliary roller displaceable between the lower support rollers and outwardly of the lower support rollers. (2) The pipe cutting machine according to claim 1, which is a registered utility model, characterized in that it includes pipe support means for supporting the pipe to be cut according to its length on both sides of the machine base. (3) The pipe support means is height-adjustable and is installed at a selected position according to the longitudinal direction of the pipe to be cut, with a one-sided pipe support member provided on one side of the machine base and the other side on the other side. The pipe cutting machine according to claim 1, which is characterized in that the pipe cutting machine is combined with a pole-shaped support stand. (4) The pipe cutting machine according to claim 1, wherein at least one of the lower support rollers is automatically driven to rotate. (5) The pipe cutting machine according to claim 1, wherein the upper pressing roller is mounted so that its position can be adjusted according to the diameter of the pipe to be cut. (6) The pipe cutting machine according to claim 1, wherein the cutting operation lever is locked and fixed at the lifting and cutting position of the rotary cutter.
