The curved chamfer around the linkage groove 205 facilitates progressive bending of the elastic wire 304, avoiding irreversible bending or breaking due to right angles.

The limit interval of the sliding of the linkage marble 301 is precisely calculated, so that the elastic metal wire 304 can be ensured to be stressed normally. When one of the interlocking pins 301 slides, the other interlocking pin 301 adjacent to and connected with the other interlocking pin will generate a certain reaction force due to the action of the elastic wire 304, and the other interlocking pin is pushed reversely.

When technical unlocking is performed by adopting iron wires and the like, the marble sliding is usually fixed and pressed one by utilizing the dimensional error of the lock core processing. In this technical embodiment, due to the action of the elastic wire 304, each of the linked pins 301 is directly or indirectly connected, and has a reaction force of linkage, so that it is difficult to keep other linked pins 301 in a fixed state during the process of technically unlocking and fixing each of the linked pins 301, thereby further increasing the difficulty of technically unlocking.
