The link (112) and cam lever (104) are mounted within cylinder section half (52) of housing (28) so as not to interfere with the deadbolt (56) and its slide (150) and deadbolt locking plate (170) that are mounted in a complementary cylinder half (51).

Abstract: An anti-theft latch is proposed. The anti-theft latch has a movable stud having a driven means therein. A pin serves to connect the movable stud with the driven means. The driven means is pivotally installed with a static latch. A guide groove is formed on the static latch. The pin is matched with the guide groove. The guide groove of the static latch is formed with a buckling portion. When the movable stud is to be unlocked by an outer force, the pin will eject and buckle the buckling portion so that the static latch can not retract to the movable stud to achieve an effect of statically locking. An auxiliary spring is further installed for pushing the driven means to move forwards. Therefore, in a normal condition, the static latch will achieve an effect of statically locking. As a result, the thief has no possibility to unlock the movable stud to move inwards and therefore, a preferred anti-theft effect is achieved.
