Simplified structure of spring bolt transmission

The utility model discloses a simplified structure of lock tongue transmission, which comprises a shell, and a main lock tongue, a bidirectional tongue, a key driving structure, an automatic driving structure and an integrated transmission structure are arranged in the shell. The key driving structure is used for unlocking and locking in a key mode; the automatic driving structure is used for unlocking and locking in an automatic mode; the integrated transmission structure is used for conducting force of the key driving structure and the automatic driving structure and driving the main lock tongue and the two-way tongue to move. An integrated transmission structure is adopted, two sets of transmission structures of automatic locking/unlocking and key locking/unlocking in an existing lock are avoided, the structure is more simplified, the occupied size is smaller, and meanwhile the transmission efficiency is higher. 本实用新型公开了一种锁舌传动的简化结构，包括有壳体，壳体内设置有主锁舌、双向舌、钥匙驱动结构、自动驱动结构以及一体化传动结构；钥匙驱动结构用于钥匙模式的解锁及上锁；自动驱动结构用于自动模式的
