Combined with the cutting assembly, it facilitates the cutting operation of the clamped plastic pipe. The scale 16 facilitates the control of the cutting length of the plastic pipe. At the same time, with the threaded engagement of the movable block 4 and the lead screw 3, combined with the sliding engagement of the slider 13 and the slide groove 12, it is easy to flexibly adjust the movable clamping part to approach the chamfering assembly, thereby driving the cut plastic pipe to approach the chamfering assembly for chamfering the end. The movable clamping part and the first vertical plate 14 are combined to... The rotational cooperation of the second vertical plate 15 facilitates flexible adjustment of the plastic pipe for rotation, making it convenient to chamfer both ends. This solves the problem in the existing technology where different equipment is needed for cutting and chamfering plastic pipes. Often, the plastic pipe is first cut with a cutting device, and then the cut plastic pipe is transferred to the chamfering device for further chamfering. This increases the labor intensity of the workers in transferring the plastic pipes, is time-consuming and laborious, and increases the processing time for cutting and chamfering plastic pipes, affecting the processing efficiency and progress of plastic pipes.
