摘要

A retention device includes a holder and an extractable casing mounted to the holder. The retention device includes a base, a cover opposite to the base, and a lateral plate extending from the base and interconnecting the base and the cover. The base, the side plates, and the cover cooperatively define a rectangular first cavity with an opening at a lateral side. The casing and the holder cooperatively define a second cavity. A size of the second cavity is less than that of the first cavity.
