As shown in figure 9, the unlocking process of the present embodiment two is as follows: when the first pulling-on piece of pulling makes the first pull head 1 push second Pull head 2, so that the second pull head 2 slides into the pull head butting section 41 that solution lock 4 is equipped with.

While pull head butting section 41 is played the role of to resistance, the solution locking face 402 that lock 40 is equipped with towards the second pull head 2 is solved The inclined end face 321 of bending part 32 is pushed, so that bending part 32 is backwards to 5 place plane elasticity deformation of chain belt；So that being coupled Card hole 320 is mobile (backwards to 5 place plane of chain belt) downwards, so that deck claw 203 is automatically separated with card hole 320 is coupled.I.e. Two pull heads 2 are detached from connecting piece 3, then the first pull head 1 of affixed connecting piece 3 can be free to slide in chain belt 5；Pass through second again Pulling-on piece pulls the second pull head 2 to be detached from solution lock 4, so that the second pull head 2 can be free to slide in chain belt 5, to realize that first draws First 1 and second pull head 2 automatic unlocking.The unlocking manner is achieved using the elastic property of connecting piece 3, by pushing away The mode for squeezing unlock is reliable and stable.

In conclusion no matter embodiment one or embodiment two are each provided with a kind of Antitheft zipper, the Antitheft zipper Lock and unlock be using connecting piece 3 elastic deformation with realize it is automatic locking or unlock, and with connecting piece 3 cooperate with Second pull head 2 of force conciliates the reasonable in design effective of lock 4, and then ensure that the stabilization of lock and unlock process can It leans on, is less prone to fault condition；It such as wears, it is only necessary to which replacing connection sheet 3 can restore to use, and the replacement of connection sheet 3 is convenient, easily In maintenance, the service life of the Antitheft zipper can be extended.
