[0009] A limiting shoulder is arranged on the inner side of the straight section, and the front surface of the mirror abuts against the limiting shoulder.

[0010] Further, the inside of the right-angle turning section is of a cavity structure, and a plurality of fixing rib plates are arranged around the insertion column inside the straight section, and the fixing rib plates fixedly support the insertion column.

[0011] Further, a cavity is formed between the plurality of fixing rib plates inside the straight section, and the cavity between the fixing rib plates is communicated with the internal cavity of the right-angle turning section.
