Specific operation process and principle are as follows：

1. locked outside room operating process：Under static state, the pin of putting into gear of main clutch is not inserted into Step Shaft gap, main clutch Device is in released state, and the fixture block of side clutch latch is located in port and the reverse slideway of left side alignment, right side and the right side are convex Platform is contacted or leaves certain interval, i.e. side clutch and is also at released state.When handle is reversely rotated, main clutch will not hinder Only driven torus is rotated, and the fixture block of side clutch then runs along reverse slideway, therefore reverse drive disk can be followed and rotated backward, And swing rod backswing is promoted, swing rod by main arm-tie, T-shaped flap, secondary arm-tie and then promotes master latch and universe rod to move again, Completion is locked action, and handle resets in the presence of driven torus two-way reset wind spring afterwards；

2. key unlocking process：Under static state, the fixture block of latch is located in port and right side contacts or stay with right boss There is certain interval.Insertion key, rotates forward handle, and driven torus follows the pin of putting into gear of rotation, main clutch will not to hinder driven Ring is rotated, and driven torus promotes right boss and then promotes cam ring to follow rotation by fixture block, and the connection of cam ring pushes away flange and rotates one Determine the left contact with thumb wheel excrescence after angle, and then promote thumb wheel and forward drive disk to rotate forward.If key is correct, outward The lock post of swivel becket will not prevent the complete rotation of cam ring, and then promote that swing rod is positive to be swung, swing promote again universe rod, Master latch and dead bolt are moved, and complete unlocking action, and cam ring, thumb wheel, driven torus are respectively in cam ring reset tension spring, thumb wheel afterwards Resetted in the presence of reset tension spring, driven torus two-way reset wind spring；If key is incorrect or without key, outer swivel becket can not be after Continuous individually to rotate, lock post prevents cam ring, thumb wheel and forward drive disk from being rotated further, and lockset can not be opened.

3. fingerprint, password unlocking process：When fingerprint recognition is correct or after correct password, electrical power, rotation, motor transmission Device promotes pin and latch side shifting inwards of putting into gear simultaneously, wherein, during pin of putting into gear is inserted into Step Shaft gap, fixture block enters just To slideway, handle is rotated forward afterwards, cam ring will not prevent driven torus from rotating, the Step Shaft gap of driven torus promote thumb wheel with Identical with aforementioned principles and complete unlocking action and forward drive disk is rotated, handle resets afterwards；If fingerprint recognition or password are known Not incorrect, transmission gear for electric motor can not promote pin and latch side shifting inwards of putting into gear, and now rotate forward handle, driven torus Can not directly drive thumb wheel to rotate, but by fixture block, right boss cam ring can be promoted to rotate forward, because not inserting correct key Spoon, cam ring is unable to complete rotation, and when connection is pushed away before flange contacts with thumb wheel left lateral sides, the lock post of outer swivel becket can prevent convex Torus is rotated further, and lockset can not be opened.

There is a kind of hidden danger in Fingerprint Lock of the prior art：Fingerprint recognition or password identification correctly complete to unlock and hold afterwards After hand resets, it is impossible to permanently ensure that clutch is completely separated, there is a possibility that other people being capable of secondary opening.This practicality Reseting procedure of the double clutch of new cam mechanism after fingerprint unlocking, including pin of putting into gear resets and latch resets two Action, and each isolated operation, do not interfere with each other.If pin of putting into gear does not reset, i.e., main clutch is not separated, but latch has been answered Position, cam ring still ensures that lockset can not be opened in the case of without correct key by the interception of right boss.Conversely, If pin of putting into gear has resetted, i.e., main clutch is separated, but latch is not resetted, fixture block is still in positive slideway, then handle is empty Turn, lockset still can not be opened.Only do not reset when pin of putting into gear, latch could occur other people in the case of also not resetting can The possibility of secondary opening, so the utility model cam mechanism is locked compared to general fingerprint, increased one insurance.

4. dally：In above-mentioned various operating process, if handle is unable to normal rotation or normal rotation is to terminal but also strong When power reverses handle, the rotating plate in limiter of moment overcomes the thrust and driven disc, driven lid of thrust spring or disk spring Skid, handle can dally.

The beneficial effects of the utility model are：

By the cam mechanism using integration, major and minor clutch is arranged in cam mechanism, compact conformation, simple, Keyhole has recovered original permeability, and the performance indications of lockset are not reduced not only, conversely also add one insurance, and And overall manufacturing cost slightly has reduction.
