[0003] Secondly, the situation that the casement window is closed but not locked often occurs in life. The outer frame of the existing casement window and the fan frame are usually connected by a bolt. There are certain defects in this structure. On the one hand, each time the window is closed, it is necessary to perform a separate operation on the latch, which is cumbersome.
