[0002] With the development of society and the improvement of living standards, people pay more and more attention to their safe life, and locks are installed on doors and windows. However, most of the existing door and window locks are provided with dead bolts at the lock body. The rotation of the handle drives the lock tongue to extend or retract the lock body to realize the functions of locking and unlocking. Of course, after unlocking, you can directly push and pull the handle to open or close the door or window sash. The door and window handle lock with this structure, its lock There is only one tongue, and the lock is still not reliable enough to drive multiple lock pins located at the upper and lower ends of the door leaf or window leaf to lock securely. Moreover, for two-door doors, one door needs to be manually locked before locking. This step is often forgotten during the door process, resulting in weak lock, easy to push open, low anti-theft level, and hidden dangers to user safety
