It is connected to an inner support system 200, which is constructed by vertically intersecting uprights and horizontal bars. The specific structure can be found in existing technologies. The uprights and horizontal bars in the inner support system are connected by disc-locks, connectors, and pins. Furthermore, a row of outer uprights 21 is provided on the outer side of the inner support system 200 along the transverse direction. Disc-locks 3 are spaced apart along the height direction on the outer uprights 21. The disc-locks 3 have circumferentially distributed locking grooves 31.

The inner end of the upper horizontal longitudinal bar 11 is provided with a socket 16 that is connected to the upper plate of the outer upright. The inner end of the lower diagonal bar is provided with an outer sleeve fastener 14, which is fastened and fixed to the outer upright 21.
