The fingerprint coded lock disclosed by the invention has the advantages that:

1. in the motion process of the dead bolt block clutch mechanism, the dead bolt block clutch driving motor rotates to drive the dead bolt block clutch screw rod connected with the dead bolt block clutch driving motor to rotate; the clutch screw rod of the square tongue block is spiral, and the clutch screw rod of the square tongue block rotates to drive the clutch swing wire of the square tongue block clamped in the groove of the clutch screw rod of the square tongue block to move up and down; the clutch swing wire of the square tongue block moves up and down to drive the clutch pressing rod of the square tongue block which is embedded with the clutch swing wire of the square tongue block to move up and down, so that the clutch pressing rod of the square tongue block presses the clutch pin shaft of the square tongue block into the clutch toggle wheel assembly of the square tongue block. When the dead bolt block clutch pressing rod presses the dead bolt block clutch pin shaft into the dead bolt block clutch toggle wheel assembly and is blocked, the dead bolt block clutch pressing rod applies a reaction force to the dead bolt block clutch swing wire, the dead bolt block clutch swing wire can deform to a certain degree to absorb the larger reaction force, and therefore the dead bolt block clutch driving motor is protected from being damaged. Meanwhile, when the square tongue piece clutch swing screw rod drives the square tongue piece clutch swing screw to move, only the square tongue piece clutch swing screw rod is clamped into a groove of the square tongue piece clutch swing screw rod, and the groove does not need to be meshed with a gear and a rack, so that the requirement on the cleanliness of the environment is not high, the fingerprint coded lock can be stably used when impurities such as dust exist, and the service life of the fingerprint coded lock is prolonged.

When the whole dead bolt device drives the dead bolt, the dead bolt is only driven by the two-stage connecting rod of the first dead bolt shifting piece and the second dead bolt shifting piece, and the two-stage connecting rod is driven to act faster compared with the three-stage and above connecting rod, so that the transmission loss between the connecting rods is reduced; and each stage of connecting rod transmission can cause certain transmission error, and the two-stage transmission has less transmission error and more accurate transmission compared with more stages of transmission.

3. When the top and bottom rods extend out, the square tongue block push piece moves forwards along the corresponding sliding groove of the lock shell to drive the square tongue block push column to move forwards; the top and bottom rod main body extends out of the lock shell by utilizing the relative motion between the square tongue block push column and the inclined surface of the inclined chute of the top and bottom rod; the dead bolt piece pushes away the post and moves forward and directly drives world pole main part along world pole inclined chute inclined plane rapid motion, has avoided the problem that the transmission ratio is slow transmission speed when the pinion rotates. Meanwhile, when the top and bottom rod main body extends out, the plurality of top and bottom rod sliding columns are embedded in the top and bottom rod straight sliding grooves to limit the movement of the top and bottom rod main body; the straight spout of world pole and the driving force that world pole traveller and world pole main part received make world pole main part atress more steady not have the upset trend on the coplanar to reduced the phenomenon that world pole main part and the straight spout of world pole increased because of the contact force that world pole motion instability arouses, it is less that the straight spout of world pole receives frictional force when restricting the motion of world pole, reduced the wearing and tearing of world pole.
