AI Technical Summary

Problems solved by technology

This part of the structure of some door locks on the market mainly relies on the gaps H1 and H2 between the lock cylinder rotating arm 31 and the lock cylinder shaft 32 to ensure that the lock cylinder rotating arm 31 can rotate freely; Button 4 moves back and forth between position A1 and position A2, and lock core rotating arm 31 is in figure 1 Free movement between the two dotted lines B1 and B2 in the center; and there is a disadvantage in this way, because the two ends of the lock cylinder connecting rod 2 are not fixed, generally only need to pull out the clamping strip outside the left front door and use a slender rod The whole car can be unlocked by poking the lock cylinder connecting rod 2 downward along the window glass; it is a great hidden danger to the anti-theft of the car
