摘要

The mechanism has connection parts (4c, 4d), each including a restoring part (E) for restoring crossbeams (6c, 6d) of a support frame. The support frame is stringed with a fly screen cloth (8) on a window frame. The parts made of springy material include two blades, which are bent to each other and possess a holding pin at their outer end. A locking pusher possesses two gliding planes separated from each other by locking tracks. Each connection part has a retaining part (H) for holding crossbeams (2c, 2d) of a window frame.
