1. An electronic self-destructing fuse structure comprising:
a lower plate structure comprising a first guide hole vertically penetrating therethrough and a first pin inserted into the first guide hole to vertically move;
a substrate module disposed at a lower side of the lower plate structure, the substrate module comprising a first through-hole positioned corresponding to a position of the first pin, the first through-hole having a reserve battery mounted therein to be activated when struck by the first pin, a second through-hole comprising a first conductive wire formed thereacross and configured to detect a short circuit, a third through-hole comprising a second conductive wire formed thereacross and configured to detect a short circuit, and an electric detonator mounted at a lower side of the substrate module, the electric detonator outputting an electrical detonation signal in response to the short circuit of the second conductive wire and being detonated according to the electrical detonation signal; and
a first safety structure disposed at a lower side of the substrate module, the first safety structure comprising a centrifugal force weight configured to be moved outwards from a center by centrifugal force and to short-circuit the first conductive wire, an impact weight configured to ascend by inertia and to short-circuit the second conductive wire, and a first detonator hole formed to allow the electric detonator to be close to a spit-back.
