[0008] In some embodiments, at least two positioning columns are provided on one of the selenium drum shell and the side cover, and a positioning hole is provided on the other one, which is matched with the positioning columns. When assembled, the positioning columns and the positioning blocks can be matched to quickly position and match the side cover and the selenium drum shell, which facilitates subsequent quick screw locking and improves assembly efficiency.

[0009] In some embodiments, the side cover and the selenium drum shell are fixedly connected by screws.

[0010] In some embodiments, at least two through holes are arranged on the side cover, and the same number of threaded holes as the through holes are arranged on the selenium drum shell in one-to-one correspondence, and the threaded end of the screw is screwed into the threaded hole through the through hole.
