Claims

[Scope of utility model registration request]

The movable piston is passed through the case body, a partition plate is provided inside the case body, multiple number rings are attached to the movable piston on one side of the case body, and a spring is placed inside the other case body. The central part of the movable piston is provided with a groove in the axial direction, and the circumferential side is provided with a circumferential groove that corresponds to the number ring. In a number lock in which the protrusion on the inside of the ring matches the groove to unlock the lock, each number ring is constructed by fitting two members in the axial direction, and one One of the members has a protrusion inside that slides into the groove of the piston, and the circumferential side is corrugated for finger rest, and the other has a number printed on the circumferential surface. A variable number lock characterized in that a slot is missing and the position of the number can be changed when the number is unlocked by fitting into each other.
