Abstract
A combination lock structure for simple password retrieval is provided. An inner sleeve is formed with a V-shaped groove. A clamping plate is provided with a V-shaped angle corresponding to the V-shaped groove. A hasp plate is provided with a hasp. A cylindrical flange of the inner sleeve is formed with a hasp groove for engagement of the hasp. A lower end of the hasp plate is provided with a convex point. A lock cylinder is formed with a protrusion corresponding to the convex point. When the lock cylinder is turned to an unlocked position, the protrusion urges the convex point to move upward and the hasp is moved upward so that the hasp is pressed against the cylindrical flange. When the hasp is engaged in the hasp groove, the V-shaped angle is engaged in the V-shaped groove.
