Using method and operating principle are as follows:
(1) utilize the open locking of magnetic control key: while not inserting magnetic control key, a plurality of magnetic conductive balls 13 are the free position on the axial ball grooves 122 of lock knob 12 respectively, has a magnetic conductive ball 13 at least by 112 of the shoulder blocks of rear lock tube 11 spacing (having at least a magnetic conductive ball 13 to be positioned at ball gear 113 places), now lock knob 12 can not rotate, and lock core is in blocking; When magnetic control key inserts the axially extending bore 124 of cage knob 12 when interior, make magnetic conductive ball 13 be ordered in axial ball grooves 122 front ends (now allowing lock knob 12 to rotate), the front end face of magnetic control key is pushed ahead shifting block 14 vertically simultaneously, shifting block 14 promotes in the driver slot position 181 of apical axis 15 compression apical axis spring 16 rear insertion driver blade 18 rear ends, after magnetic control key puts in place, when rotating key, drive lock knob 12 to rotate, lock knob 12 drives shifting block 14 and driver blade 18 to rotate, driver blade 18 and then 20 rotations of driving dead bolt, thus reach unlocking function.When the driver slot position 181 of driver blade 18 ends and the not contraposition of leading section of shifting block 14, insert magnetic control key to unlocked position, key leading section promotes driver blades 18 travel forward (now shifting block 14 can not insert in the driver slot position 181 of driver blade 18 rear ends) by shifting block 14, screw key drives cage knob 12 and shifting block 14 to rotate simultaneously, when the leading section of shifting block 14 goes to 181 positions, driver slot position of driver blade 18 ends at once, driver blade 18 is motion backward under the effect of driver blade spring 17 elastic force, the driver slot position 181 that makes shifting block 14 insert driver blade 18 ends, thereby can drive driver blade 18 to rotate and realize release.Wherein, in magnetic control key rotary course, its mechanism coordinating with lock knob 12 key positions 121 is subject to the restriction (rear baffle ring 10 does not rotate) of corresponding slot position 103 on rear baffle ring 10 keyholes 102, can not arbitrarily extract, can only in groove position 103 contrapositions that turn to key position 121 and keyhole 102, just can extract key, thereby reach the object of lock core return.
(2) utilize the open locking of handle 32: key not in the situation that, shifting block 14 is subject to the effect of apical axis 15 and apical axis spring 16, thereby return to shifting block holding tank 123 and driver blade 18, departs from, and has removed the control of cage knob 12 for dead bolt 20; Now can utilize the other end of anti-theft lock core to realize release and locking, i.e. twisting is arranged on the handle 32 of front lock tube 31 axially extending bores, by handle 32, drives driver blade 18 to rotate, and then drives dead bolt 20 to rotate.
The present invention is not limited to above-described embodiment, based on simple replacement above-described embodiment, that do not make creative work, should belong to the scope that the present invention discloses.
