Four, anti-technology unlocking is strong: this lock adopts 3 cover teeth groove systems, there are 4 slide plates in every cover teeth groove system, this 3 cover totally 12 slide plates promptly separately are close to again each other, almost can't a slice a slice is interference-free stir, add no spring, slide plate can't be put, therefore, the difficulty of technology unlocking is very big.

Five, volume simple in structure is little: usually, lock will increase size of key, must increase volume, strengthen the difficulty of technology unlocking, must want mechanism's complexity, and mechanism's complexity not only increases volume again, also can increase difficulty of processing, improves cost of production.

This lock adopts no spring beaming type slide vane structure, and simple in structure, volume ratio is less, and the lock body profile diameter is less than 19 millimeters, and length is less than 21 millimeters.If reduce some size of keys, then volume can also further dwindle.Because volume is little,, use extensively so be fit to make lockset, the lock core that meets various requirement.
