description The utility model discloses a mechanical unlocking mechanism, and belongs to the field of unlocking mechanisms of locking devices. Comprising a first unlocking wheel mechanism, a rocker arm mechanism, a second unlocking wheel, a shell cover part, a neutral pin, a shaft and a steel wire rope. The lower ends of the first unlocking wheel mechanism, the rocker arm mechanism and the second unlocking wheel are sequentially installed on the shell cover component through shafts. The neutral pin sequentially penetrates through the first unlocking wheel mechanism, the second unlocking wheel and the shell cover component and is used for keeping limiting of the mechanism in the non-working state of the unlocking mechanism. The shaft is manually rotated and drives the rocker arm to rotate, the rocker arm drives the first unlocking wheel through the spring, and the first unlocking wheel drives the steel wire rope to achieve primary unlocking of the locking device. The rocker arm drives the second unlocking wheel through th
