Technical field
The present invention relates to field of lockset, the anti-structure that kinks of specifically a kind of shifting part of lock core.
Background technology
Illegal method for unlocking popular in the world is a lot of now: hit that spoon (English be bump lock) is unlocked, drill bit is unlocked,
Pull lock core is unlocked, picklock is unlocked etc..And prevent illegal unlocking technique also with occurring in that many kinds: prizing-proof lock core, anti-drilling
Lock core, anti-pull out lock core, anti-twistlock core (anti-snap), anti-bump key lock core (anti-bump) etc..
At present, some robbers also begin to implement theft using the means that violence is unlocked, and they are entangled with special socket bar
The lock core head of outer side of door one or the lock core head clamping outer side of door one with locking pliers, then firmly pull or left up and down
The right side is firmly pulled, and makes the weaker middle part fracture of lock core destroy lock core structure, because the parts in lock core mutually can depart from,
The lock core of fracture can be extracted and open lock by robber easily.
Further, since lock core body is made of copper, and copper material is softer, when lock core body is clamped by locking pliers, locking pliers
Tooth mouth can be easily absorbed in copper material and being engaged with lock core body phase, so that locking pliers is twisted into two parts lock core body and lock opened become can
Energy.Existing lock core is unlocked for such violence and is also lacked protective capacities.
