When cutting, the sliding plate 301 can be moved, and the triangular indicator block 304 is observed to be on the scale line 3. 05, thereby realizing the control of the distance between the two arc-shaped positioning plates 303 and the left limit plate 205, and rotating the first turntable 307. The rotation of the first turntable 307 drives the bidirectional lead screw 306 to rotate. The rotation of the bidirectional lead screw 306 drives the two moving rods 302 to move toward the middle at the same time, so that the two arc-shaped positioning plates 303 effectively support the surface of the metal pipe fittings, and the cutting machine cuts on the left side of the arc-shaped positioning plates 303, thereby realizing the purpose of accurately controlling the cutting length of the metal pipe fittings. At the same time, when cutting the metal pipe fittings, the rotation of the rotating motor 401 can drive the driving gear 402 to rotate, and the rotation of the driving gear 402 drives the driven gear 403 and the rotating cylinder 204 to rotate, thereby driving the metal pipe fittings to perform rotary cutting.
