Problems solved by technology
Because the lock tongue slides in the slideway, compared with the locks in CN1847594A and CN101245680A, the noise interference is reduced, but when the lock tongue is retracted inwardly, it also drives the movement of the rocker arm, so the rocker arm will inevitably produce certain noise. In addition, the connecting rod in the strike lock is an unconventional part, which is difficult to process and manufacture
