Claims

[Scope of utility model registration request]

A driven gear with a tool case fixed to its side surface is attached to a housing so as to be rotatable around the central axis of the driven gear, and the driven gear, the tool case, and the housing include the central axis and are attached to the sides of the central axis. The tool case is provided with two rotatable support rollers whose circumferential surfaces face the central axis, and a circular cutter and a grooving roller facing the support rollers. A lever that supports rollers at one end at a predetermined interval in the axial direction, and a camshaft to which an eccentric cam that engages with the other end of the lever is fixed, are rotated around an axis parallel to the central axis. The proximal end of a clutch arm, which is movably mounted and has a cam roller pivotally supported at its tip, is attached to the camshaft via a one-way clutch, a cam plate for pushing the cam roller is attached to the housing, and the cam roller is attached to the driven gear. Two driving gears that mesh with each other with an interval equal to or more than the width of the opening are pivotally supported in the housing, and a gear device that transmits rotation of an output shaft of a motor attached to the housing to the driving gear is built in the housing. Further, a pipe cutting and grooving machine comprising a pipe gripping clamp having a locking cam pivotally supported at one end of a substantially C-shaped jaw at a position opposite to the tool case of the housing.
