Small-pipe-diameter cutting machine with smooth cut

The small-pipe-diameter cutting machine comprises a base, two installation frames are fixedly installed at the top end of the base, a plurality of screw holes are formed in the adjacent sides of the two installation frames, one end of each of the two corresponding screw holes is fixedly connected with a fixing shaft, and the other end of each of the two corresponding screw holes is fixedly connected with a cutting head. According to the small-pipe-diameter cutting machine with the smooth notch, the two limiting shafts are arranged to be matched with the movable rod, the movable rod can be driven to move downwards, a pipeline placed between the two limiting shafts is pressed, the pipeline is fixed through the movable rod, and therefore the pipeline can be cut smoothly. According to the pipeline cutting device, a limiting shaft and a movable rod are arranged, a pipeline needing to be cut can be stably placed between the limiting shaft and the movable rod, according to the design, a clamping switch does not need
