Background technique

Most of the various mechanical anti-theft locks currently on the market simply use pins or blades, which cannot prevent simple unlocking tools from being inserted into the lock body to vibrate and provocate components in the lock body to open technically or torsionally destroy them. General tumbler locks are simple in structure and process, and do not have anti-technical opening and anti-destructive capabilities, are very easy to be opened, and keys are easy to imitate, so they cannot play an anti-theft role. Although the general blade lock head has good torsion resistance and anti-picking performance, the mutual opening rate is high, and it is very easy to be illegally opened by a key with a similar code, causing the lock head to fail. In sum, the above two types of locks cannot satisfy the user's increasing requirements for anti-theft security.
