Password-retrieving apparatus for coded lock

A password-retrieving apparatus for a coded lock, comprising a lock body (11), wherein a combined body of an elastic wheel (4) and an inner wheel (5) is arranged outside the lock body (11), and is mounted between a lock shell (9) and a lock cover (10) through a big spring (13);

• the lock body (11) is connected to a lock handle (12);
• a lock cylinder (1) is arranged in the lock handle (12);
• a movable adjusting rod (3) is arranged in the lock body (11);
• a small spring (8) is arranged between the adjusting rod (3) and a lock cover (10);
• the adjusting rod (3) is provided with a protruding point (31);
• the inner wheel (5) is provided with an avoidance clamping slot (6) and a limit (7);
• the lock cylinder (1) is driven to rotate under the rotation of a spare key;
• the lock cylinder (1) is engaged with a first bump (21) on a toggling disk (2) for driving the inner wheel (5) to rotate in a staggered manner;
• the lock body (11) moves relatively under the action of a big spring (13);
• the adjusting rod (3) moves inwards under the action of the small spring (8);
• and the toggling disk (2) is rotated to drive the inner wheel (5) to rotate;
• when the inner wheel (5) is rotating drived by the toggling disk (2), an elastic wheel (4) sleeved outside the inner wheel (5) does not rotate;
• the protruding point on the adjusting rod (3) and the limit (7) in the inner wheel (5) are clamped;
• and a password displayed on a password wheel outside the inner wheel (5) is the retrieved password.
