(3) due to the continuous pushing of the handle block 30 and the flexibility of the connecting sheet 33, the connecting sheet 33 enters the corresponding key hole 42 along with the diversion trench 5;
(4) when the connecting sheet 33 completely enters the key hole 42, namely the locking tooth 34 is clamped with the corresponding upper marble 23, the locking tooth 34 enables the upper marble 23 to push the lower marble 26 to stretch up and down, and when the bottom of the upper marble 23 is positioned at the bottom of the lock core and is in a flush state, the lock core 9 is unlocked;
(5) when the connecting piece 33 completely enters the key hole 42, the connecting rod 35 contracts to the shortest, the upper end of the clamping block 37 is clamped with the clamping ring 41, then the handle block 30 is rotated to drive the lock column 4 to rotate, the rotary disc 19 is driven to rotate through the rotation of the chain 21, and the connecting line 48 is driven to contract at the same time, so that the lock bolt 15 contracts, the lock bolt 15 is separated from the clamping groove 7, the locking ring 1 automatically pops out due to the elasticity of the first spring 10, namely the locking ring 1 is opened, and the unlocking is finished;
(6) when the lock ring 1 is pressed into the corresponding first adjusting groove 6 and the second adjusting groove 14, the bolt 15 directly pops up the bolt 15 due to the elasticity of the second spring and is clamped with the clamping groove 7, the lock ring 1 is locked by the lock cylinder, the connecting line 48 recovers the initial length due to the popping up of the bolt 15, the rotary disc 19 is driven to rotate, the lock cylinder 4 is rotated through the transmission of the chain 21, and the lock cylinder 9 is accurately recovered to the initial position by adding the positioning block 8;
(7) when the connecting sheet 33 is pulled out, the upper marbles 23 are directly ejected out due to the elasticity of the third spring 27 to restore the initial position, and meanwhile, the lower marbles 26 enter the corresponding upper marble groove 44 to fix the lock cylinder 9;
(8) when the key 46 is pulled out, the protrusions 12 on the fixture blocks 37 increase the frictional force between the engagement, so that the connecting rod 35 can be driven to continuously extend, the fixing ring 36 is driven to continuously recover and fix the umbrella-shaped connecting sheet 33 into a cylindrical shape, and the cylindrical connecting sheet is restored to the initial state, and after the connecting sheet 33 is completely pulled out, the fixture blocks 37 are separated from the lock holes 22, namely, the key 46 is pulled out.
