Abstract
The invention discloses a bidirectional lock high in antitheft performance. The bidirectional lock comprises a first lock case and a second lock case. A first lock container is arranged in the first lock case, and a second lock container is arranged in the second lock case. A lock cylinder assembly matched with a key is arranged in the first lock container and the second lock container. A connecting rod is arranged at the upper end in the first lock case and the upper end in the second lock case. A connecting shaft for connecting the first lock container and the second lock container is further arranged at the lower end in the first lock case and the lower end in the second lock case and sleeved with a stirring piece. Clamping structures are arranged between the first lock container and the connecting shaft and between the second lock container and the connecting shaft. During destructive unlocking, even though the connecting rod is struck off, the connecting shaft cannot slide out of the lock cases, and therefore destructive unlocking cannot be completed. The bidirectional lock is simple in structure, convenient to assemble, easy and convenient to machine, solid and firm.
