Methods three

A dustproof padlock usually has a lock core. In addition to the hole for the key, there are several round holes in the lock center. These holes correspond to the holes in the lock body, and a spring and two copper pins of different height can be placed in the lock.

After the key is inserted, because the tooth position is high and low, the two marbles are on top of different heights, if all the two marbles in the hole and the circumference of the lock center is equal, the lock center can be turned in the lock body, then, the lock is opened.This is how padlocks work.If the padlock key is lost, you can purchase a master key.

When an i-shaped marble is lifted due to the rotation of the center of the lock, the i-shaped head will touch the shoulder of the eye of the marble, and cannot be lifted up, that is, retract to the eye of the marble.To solve this problem, it is necessary to be very careful to push the rotating force of the bar, and apply a very light rotating pressure to the marbles. The situation of the marbles is to use a single hook without testing, and the difference between the standard marbles and the h-shaped marbles in the retraction can be felt.To the full top of the i-shaped marbles, to know the appropriate playback, (three ring lock in playback because the lock itself is elastic, so the playback strength is not good to grasp), there is a method called "push ten times three", {hit a ratio, to open the direction of 10 degrees, in playback 3 to 4 degrees}.It is necessary to relax the rotating force of the reverse locking center so that the big head can pull back from the blocking of the eye edge of the marble. However, the lock has always been the heart of the opposite, may also make the original has been good on the marble fell down again and was locked.

If this happens, you must start over with another marble until you are successful.
