[0021] Embodiment

[0022] Please refer to Figures 1-4 The present application provides an electric heater for glass tube, which comprises a shell 10 and an inner container 20. The shell 10 is provided with a vertical through hole. A plurality of conductive screws are installed on one side of the shell 10. Specifically, the shell 10 comprises an upper cover plate 101, a lower cover plate 102 and a support frame. The upper cover plate 101 and the lower cover plate 102 are locked to cover the support frame by bolts. The upper cover plate 101, the lower cover plate 102 and the support frame form the shell 10 with an internal cavity. The upper cover plate 101 and the lower cover plate 102 are provided with holes for inserting the glass tube, thereby supporting and protecting the inner container 20. Further, the support frame comprises a U-shaped surrounding plate 103 and an insulating sheet 104. The insulating sheet 104 and the surrounding plate 103 form a support frame in the shape of a mouth. The insulating sheet 104 is provided with conductive screws. An external power source is connected to the electric heating wire 2011 of the inner container 20 through the conductive screws. The insulating sheet 104 can prevent the shell 10 from being electrified as a whole, thereby playing a protective role.
