2）It opens up jagged in first panel outer rim, the second through hole connected with notch, stud is offered in second panel One end is embedded into after sequentially passing through notch and the second through hole inside door-plate, and bolt one end is extend into inside door-plate and the stud It links together, it is simple in structure, it is easy for installation so that the integral installation structural strength bigger of lock, so as to have Effect protection lock core, avoids lock core from being prized easily bad, pick-proof effect is more preferable；

3）First panel and second panel outer mask are equipped with shield, and third through-hole, the lock core of lock core are offered on shield Hole is exposed from third through-hole, can further be protected lock core, lock core be avoided to be prized easily bad；

4）Location hole is offered at the top of stud, screw is provided on the inner surface of shield, screw is screwed into described fixed It is simple in structure inside the hole of position so that shield it is easier for installation, and structural reliability is high；

5）First panel between second panel by several screw lockings together with, screw one end pass through second panel after It being locked in first panel, the head of screw is pressed on the inner surface of second panel, simple in structure, and due to screw Head is pressed on the inner surface of second panel so that criminal is difficult to by unscrewing screw be pried away from first panel With second panel, the mounting structure of first panel and second panel is destroyed, so as to effectively protect lock core, avoids lock core light Easily prize bad, pick-proof effect is more preferable；

6）Anti-rotation sheet is installed on the outside of the lock core hole of lock core, inside the groove, improves the pick-proof of lock, anti-drilling effect Fruit avoids criminal from being pried away from lock core easily by drill bit.
