Each time you change the character, the line spring and the plane Cormorant sound reliably to localization and once to stop the number ring out, to hold so that each number ring does not easily change its position.

Further, one coil spring is fitted around the rear end of the shaft and is inserted into the recessed chamber in the front part of the rear lid, and the last localization ring immediately in front of it is elastically engaged. , So that each tooth plate and each stereotactic ring have the control lid set with a secret number for opening this lock, and when it is turned about 180 degrees to the right from the set position, the stop protrusion is the protruding edge of the front end of the shaft. Can be stopped by. Due to this pivoting of the control lid, the setting ring immediately behind it is pushed and moved, so that each tooth plate and each localization ring are moved all the way back, compressing the coil spring. As a result, each number ring is free to rotate apart from each number ring that is engaged with each tooth plate, and a new secret number can be set. After setting the new number, turn the control lid to the left again about 180 degrees to return it to the original setting position, and the elasticity of the coil spring pushes the setting ring, each tooth plate and each localization ring forward. It is done and it returns to the setting position.
