Until chain pin 311 departs from chain disk 211, after chain disk 211 loses the constraint of chain pin 311, towards the right side along Fig. 9
When drawing chain disk 211 outside side, you can drive dead bolt 11 to reach the purpose of unblock.
If necessary to tripper is exited from chain disk 211, it is necessary to allow tripper along the direction of Fig. 9 towards left side after
A continuous mobile segment distance.Because lock claw is provided with groove, after unlocking sleeve 203 crosses lock claw, lock claw rests on unlocking sleeve 203
In circular trough.At the same time the Magnet for being embedded in the one end of mandrel 208 is attracting with the backboard of internal box.When tripper is moved towards right side
When dynamic, the Magnet 205 and mandrel 208 for being adsorbed in the backboard of internal box is not first moved with the movement of tripper, due to unblock
Set 203 is fixedly connected with mandrel 208 by straight pin 206, therefore, unlocking sleeve 203 is also motionless.So unlocking feature 201 with
Moving to right for tripper is gradually drawn close to unlocking sleeve 203,203 two parts of unlocking feature 201 and unlocking sleeve is mutually supported
Connect.When tripper continues to move to right, unlocking feature 201 forced and moved after unlocking sleeve 203, is so stuck in unlocking sleeve 203
Lock claw in circular trough is sliding along the groove of unlocking sleeve 203, because unlocking feature 201 has been abutted with unlocking sleeve 203, does not produce
Dead slot, lock claw will not be snapped in inside dead slot.So unlocking feature 201 just can cross lock claw, tripper is smoothly exited.
