The invention discloses a drawing-out computer hardware interface with dust-proof and short-circuit-proof functions, which comprises an interface main body and a computer baseboard, wherein the interface body is composed of a shell arranged on the side surface of the interface main body and a fixing plate arranged on the side surface of the shell; and the fixing plate is nested in the shell. According to the drawing-out computer hardware interface with dust-proof and short-circuit-proof functions, as a sliding groove and a slider are arranged, the slider moves easily in the sliding groove to draw out the hardware interface, residual dust can be cleaned conveniently, and thorough circuit inspection is also facilitated; as a dust-proof cover is arranged, entering of dust can be effectively reduced, normal use and cooling of the interface are ensured, radiation is reduced, and the body health of a user is maintained; and as a fuse and a protective sheath are arranged, short circuit can beprevented, and the absolute safety of the interface and the user is ensured.
