[0002] In the modern security protection system, locks are an important component, and their safety and reliability directly affect the safety of people's lives and property. Traditional locks usually use complex mechanical structures to achieve the driving connection between the lock core and the lock tongue, such as pin-tumbler locks and magnetic locks. Although these locks have a certain share in the market, they generally have problems such as complex structures and high costs, and cannot fully meet the needs of modern society for high-security locks.

[0003] In addition, traditional locks usually use complex mechanical structures to achieve the driving connection between the lock core and the lock tongue. For example, the common multi-link connection transmits power through a series of connecting rods to control the lock tongue to move. It is highly flexible, but it also has the problem of complex structure. Another example is the cam connection, where the cam rotates with the shaft on the lock housing, and a straight rod is used to connect the cam to the lock tongue and the lock core to achieve force transmission.

[0004] Although these traditional connection methods meet the basic needs to a certain extent, they have many parts, which not only makes assembly difficult but also increases the cost. The lock core is large in size, leaving a large room for improvement. Therefore, the present application proposes a lock core with a simpler structure and fewer accessories. Summary of the invention
