Preferably, the centre of described inner core is provided with a keyhole, is provided with the first lead and second lead of through keyhole in keyhole, and the first lead, the second lead mate with the first gathering sill of on the key, second gathering sill respectively.First gathering sill, second gathering sill lay respectively at the both sides of alveolus.
Preferably, the centre of described inner core is provided with a keyhole, and the lead being provided with through keyhole in keyhole only arranges one, mates with key gathering sill.
Preferably, the centre of described inner core is provided with the keyhole of a D font, in the direct through keyhole in the plane place in keyhole, forms the guide surface of key.
Preferably, on described core retainer plate, symmetry and core retainer plate axis parallel are provided with the first groove, are inserted with one first locking slide plate and one second locking slide plate in two the first grooves respectively.
Preferably, the first locking slide plate place on the corresponding core retainer plate of described inner core and the second locking slide plate place are provided with vane slot hole.
Preferably, the corresponding first locking slide plate place of described inner core and one second locking slide plate place are all provided with an extrapolation element.
Preferably, one end of described inner core is provided with a stopper slot, and a part for a pin is positioned at core retainer plate, and another part of pin slips in stopper slot.
Preferably, described interior pressure limited block is provided with step.
Preferably, described key is V-arrangement toward the position shape of inner core, and the sub-place of inner core corresponding keys is provided with V-shaped groove, outwards movement under super torque forces.
Positive progressive effect of the present utility model is: the utility model anti-theft lock end just realizes idle running handling power under super torque forces, prevents from arbitrarily being opened, improves theftproof performance.
