Zusammenfassung:	The utility model provides an automatic switching device for the cross section of a coil pipe and an automatic coating device of the coil pipe formed by additionally installing a coating component. The automatic switching device for the cross section of the coil pipe comprises a coil pipe damp adjusting and guiding component and a coil pipe O/D type cross section continuously forming component, wherein a wheel shaft B of a first idler wheel of the coil pipe O/D type cross section continuously forming component can move along with a groove type axle bole arranged on a bracket up and down, a second idler wheel is provided with at least one of B type grooves along with the outer periphery, and the first idler wheel is compacted with the second idler wheel by the means that the wheel shaft B is downwards pressed by a compacting component. The automatic coating device is reasonable in design structure and high in practical applicability, so that the outer coil pipe is kept to be tensioned and straightened by the c
