[0029] like Figure 1 and Figure 3 As shown, exemplarily, the first frame 1 includes two parallel plates 11 and four crossbeams 12 perpendicularly connected at the four corners between the two plates 11. Along the length of the plates 11, the adjacent sides of the two crossbeams 12 at the same end form a first channel with the two plates 11. Specifically, the side of the crossbeams 12 closest to the transverse axis of the plates 11 forms the first channel with the two plates 11. Along the height of the plates 11, the adjacent sides of the two crossbeams 12 on the same side and the adjacent sides of the two pipe boxes 2 form a second channel with the two plates 11. Specifically, the sides of the crossbeams 12 and the pipe boxes 2 closest to the longitudinal axis of the plates 11 are flush and form the second channel with the two plates 11.

[0030] like Figure 1 and Figure 2 As shown, furthermore, right-angle sheet metal 21 is provided at the four corners of the side of the two tube boxes 2 away from the axis of the first frame 1. The right-angle sheet metal 21 has two mutually perpendicular sides.
