The invention discloses a bending center hinge cutter pressing rod with a protection mechanism. The hinge cutter pressing rod comprises an upper hinge cutter pressing rod body and a lower hinge cutter pressing rod body. The upper hinge cutter pressing rod and the lower hinge cutter pressing rod can move up and down relatively; the hinge cutter pressing rod is made of a magnet material; a magnet block, a protection pin shaft and a first inductive switch are arranged below the hinge knife pressing rod, and the magnet block and the hinge knife pressing rod are attracted and fixed; an opening structure matched with the hinge knife pin shaft is arranged at the lower end of the lower portion of the hinge knife pressing rod. During normal work, the hinge cutter pressing rod drives the hinge cutter pin shaft and the hinge cutter side cutter to slide downwards along a sliding way in the hinge cutter body; when the hinge cutter side cutter generates clamping stagnation in the hinge cutter body and the acting force exce
