Claims

[Scope of utility model registration request]

A latch bolt that is provided with an elastic force in the projecting direction at all times so that it can be retracted from the front; a retractor that is slidably provided within the lock case and connected to the latch bolt so that it can be retracted from the front; It has a latch hub that connects the tractor in a retractable manner and is rotated by a connecting shaft of a knob or lever, and the knob or lever is unrotated by the elastic force of a spring that biases the retractor in the return direction. In a latch lock that is held in a moving position, the springs are comprised of a spring A that always biases the retractor and a spring B that is selectively used depending on the knob or lever, and can be operated from the front side. a screw member and a movable plate that can move forward and backward along the thread groove when the screw member rotates, one end of which abuts against the movable plate, and the other end of the spring pushing member that is loosely inserted into the screw member. A latch lock in which a part is interposed between the abutting ends of a spring B and a retractor.
