[0002] With the increasingly wide application of electronic control modules in automobiles, automobiles have become more and more intelligent, and the anti-theft performance of automobiles has also been widely concerned. The steering shaft lock is a steering shaft locking device. After the steering shaft is locked, the automobile cannot turn. Even if the automobile can be started, because it cannot turn, the automobile cannot be driven away. Therefore, the steering shaft lock plays an anti-theft role. As an important safety module on automobiles, higher requirements are put forward for the safety and reliability of the steering shaft lock. In order to ensure the safety of automobiles, the steering shaft lock needs to be tested before leaving the factory.

[0003] In the prior art, simply by workers observing the movement of the locking tongue of the steering shaft lock to judge whether the unlocking and locking of the steering shaft lock are successful, not only the testing steps are relatively cumbersome, but also the observation by manual is prone to large errors, which easily causes uneven production quality of the shaft lock, affects subsequent normal use, and has poor practicability.
