The utility model relates to a high damage tolerance type metal connecting structure who contains punctiform crackle inhibition zones, it includes at least one first plywood and at least one second plywood, be equipped with an inhibition zones and first circular extended region around the first connecting hole on the first plywood, be equipped with the 2nd inhibition zones and the circular extended region of second around the second connecting hole on the second plywood, first plywood and second floor inter -plate separate and set up and pass first connecting hole with the connecting piece and be connected first plywood and second plywood afterwards with the second connecting hole, and first circular extended region does not align with second circular extended region position. The utility model discloses a high damage tolerance type metal connecting structure who contains punctiform crackle inhibition zones presets banding crackle inhibition zones in the region that stress concentration easily cracked, and when crack growth arrived banded crackle inhibition zones, the expanding cracking path of change crackle slowed down crack growth speed, realizes the inhibitory action to crack growth.
