[0007] The lower mounting support plate is used to fix the other end of the heating tube and to make the heating tubes parallel to each other.

[0008] In one or more embodiments of the present invention, the heating tube is an infrared heating tube.

[0009] In one or more embodiments of the present invention, the cable tube is a glass tube, and the upper mounting support plate is made of metal material to form an integrated structure.

[0010] In one or more embodiments of the present invention, the pressure plate group includes a central triangular pressure plate, a first straight plate, a second straight plate and a third straight plate arranged around the central triangular pressure plate; and the wiring tube is placed between adjacent heating tubes.

[0011] In one or more embodiments of the present invention, the heating tube is provided with a neck, and a positioning plate is welded between adjacent heating tubes, and the positioning plate presses the cable tube to prevent it from loosening.

[0012] Compared with the background technology, the utility model has the following effects: adopting the above technical solution, the wiring is reasonable, the protection is safe, the electric contact is stable and not loose, the structure is compact and the space is fully utilized, and the number of pipes and power are greatly increased in the same space.
