Zusammenfassung:	The utility model relates to a machinery used for fabricating energy saving lamp tubes, in particular to a tube bending device of a dual-spiral type energy saving lamp tube. The utility model comprises a droppable and rotary tube-winding device, a bending die which is positioned on the tube-winding device, and a support. The left side and the right side of the bending die are equipped with a parison tube guide device which comprises a guide rail and a jig turnover panel device. The jig turnover panel device is positioned on the guide rail. The parison tube guide device is fixed on the support via a support rod. When the utility model is used, the heated parison tube is fed into the tube-winding die via the parison tube guide device tube to carry out tube winding, thereby realizing the mechanized bending of parison tube, reducing the labor intensity of operators, realizing the stable quality and increasing the production efficiency.
