An upper and a lower locking points (5 and 10) are fixed on a frame of the door leaf (2) which has different sectional planes with the main locking body (3); an upper lateral rod (4) is connected between the upper locking point (5) and the upper connecting rod (6); a lower lateral rod (11) is connected between the lower locking point (10) and the lower connecting rod (9). After adopting the structure, the main locking body (3) drives the upper and the lower locking heads (8 and 13), the upper and the lower cross locking points (7 and 12) to lock, via the upper and the lower connecting rods (6 and 9). Simultaneously, the upper and the lower connecting rods (6 and 9) drive the upper and the lower locking points (5 and 10) to lock, via the upper and the lower lateral rods (4 and 11), so that different sectional planes are provided with a plurality of locking points matched with locking holes of a doorframe (1). The utility model has the advantages of simple structure, better antiprizing performance, etc.
