A lock, comprising an upper casing (1) and a bottom plate (30) fixedly connected to one another. An accommodating space is formed between the upper casing (1) and the bottom plate (30). A surface of the upper casing (1) is provided with an insertion hole (11). A locking mechanism is provided within the accommodating space. The locking mechanism comprises a lock hook (2) matching the insertion hole (11), and a control device used for controlling the lock hook (2) to move. The lock hook (2) comprises a hook portion (23) capable of entering a lower part of the insertion hole (11), and a connecting portion (22) controlled by the control device. When a combination is correct, the hook portion (23) is capable of moving to one side of the insertion hole (11). When the combination is wrong, the connecting portion (22) is limited by the control device, and the hook portion (23) is limited at the lower part of the insertion hole (11). The insertion hole (11) is provided with a side plate at a front side of the hook portion (23). The side plate comprises an inclined portion (111) located at an upper end, and a vertical portion (112) located at a lower end. An upper end of the inclined portion (111) is outwardly inclined. |
