[0007] A further implementation scheme of the utility model is that the first bending member is overlapped with the top and the inner side of the furnace vertical plate respectively, and the bottom is welded to the inner side of the furnace vertical plate.
[0008] A further implementation scheme of the utility model is that the second bending piece overlaps the top and the outer side of the furnace vertical plate.
