1. A specimen preparation component of a genome extraction device, comprising:
an outer chamber, configured to receive the specimen, partitioned into a plurality of first spaces by an outer chamber partition wall;
an inner chamber, configured to accommodate a reagent to be used for analysis of the specimen, coupled to the outer chamber through upper openings of the plurality of first spaces and partitioned into a plurality of second spaces by an inner chamber partition wall, wherein, in the inner chamber, upper openings and lower openings of the plurality of second spaces are sealed by a sealing member;
a cover configured to cover the upper openings of the plurality of first spaces of the outer chamber and having a first protrusion member for tearing a first sealing member sealing the upper openings of the plurality of second spaces formed on a bottom surface of the cover;
a safety clip detachably coupled to the outer chamber and having a cover support member that allows the first protrusion member and the first sealing member to be spaced apart from each other in a state in which the safety clip is combined with the outer chamber, and
wherein the safety clip includes:
an outer chamber coupling portion at least partially surrounding a perimeter of an outer surface of the outer chamber; and
an inner chamber coupling portion extending from the outer chamber coupling portion toward the inner chamber,
wherein the inner chamber has a fixing portion coupled to the inner chamber coupling portion at a portion facing the inner chamber coupling portion,
when the safety clip is detached from the outer chamber, the inner chamber is allowed to descend downward toward the outer chamber.
