One of the accessories for swing doors and windows is the hinge. Hinges are installed outdoors, that is, the hinges of inner doors and windows are installed indoors, and the hinges of outer doors and windows are installed outdoors. Door and window locks are usually swing locks, and the handle is usually combined with the lock. A plug is an essential part for opening doors and windows from the outside, which can prevent wind from blowing through the door and window frames and frequent collisions. However, the stability of the fixed plane formed by two hinges and three points of the stopper is limited.
