Compared with the prior art, the plug-in pins at the upper and lower ends of the window frame need to be inserted into the lock slot of the door frame. The present application needs to operate the driving assembly to lock the first plug-in plate and the second plug-in plate with the upper and lower ends of the window frame, respectively, thereby achieving the effect of facilitating the locking operation of high windows.
[0023] 2. By arranging the driving assembly, operating the handle, the handle rotates around the connecting column, and in the process of rotating, the first operation rod moves along the first operation slot, and the second operation rod moves along the second operation slot. When the handle rotates, the first operation rod and the second operation rod also generate horizontal force, thereby also driving the first plug-in plate and the second plug-in plate to approach or separate from each other.
[0024] 3. By arranging the limiting slot, when the first plug-in plate and the second plug-in plate approach or separate from each other, the first limiting rod and the second limiting rod slide along the limiting slot, thereby enhancing the limitation of the movement track of the relative movement of the first plug-in plate and the second plug-in plate.
