[0043] Based on the above embodiments, Figures 11 to 13As shown, taking the second locking rod 4 as an example, the structure and connection relationship of the first locking rod 3 and the second locking rod 4 are described. The second locking rod 4 includes a locking rod body 401, a locking rod protrusion 402, a first branch rod 403 and a second branch rod 404. The locking rod body 401 is the main part of the entire second locking rod 4, and its head end is located on the right side, which is used to connect with the window frame on the right side. The upper rod surface protrudes with a locking rod protrusion 402 near the head end, and a double bifurcation structure is formed at the tail end of the locking rod body 401, including a parallel The first sub-rod 403 and the second sub-rod 404 are arranged at a certain distance, and a plurality of teeth 40301 meshing with the gear member 7 are arranged on the side of the first sub-rod 403 facing the second sub-rod 404. The first sub-rod 403 is hollow inside, forming a slide groove 40302 for accommodating the second sub-rod on the first locking rod 3 to enter, and the second sub-rod of the second locking rod is slidably connected to the slide groove 40302, and at the same time, the second sub-rod 404 on the second locking rod 4 is slidably connected to the first sub-rod slide groove of the first locking rod 3. The first locking rod 3 and the second locking rod 4 form an alternately plugged sliding connection mode, and at the same time, the teeth on the two first sub-rods are arranged facing each other, and the gear member 7 meshes with the upper and lower rows of teeth at the same time to form a reverse meshing. When the gear member 7 rotates, the first locking rod 3 slides to the left, and the second locking rod 4 slides to the right.
