DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0020] Figures 1-5 For a specific embodiment of the utility model, the embodiment is a transmission lock that realizes 180° rotation. The fixed plate 6 is fixed with the fixed clamp 7, the fixed clamp 7 is slidingly connected with the sliding plate 5, the sliding plate 5 is fixedly connected with the pin 2, the pin 2 is slidingly connected with the fixed plate 6, the wheel guard plate 1 is fixedly connected at the center of the fixed plate, the wheel guard plate 1 is provided with the gear 4 connected with the handle, the gear 4 drives the rack 3 to slide the sliding plate 5, the handle rotates 180° to realize one opening and closing cycle of the window sash.

[0021] One side of the wheel guard 1 is provided with a sliding groove 101, and the sliding plate 5 is slidably connected to the sliding groove 101. A rack sliding track 102 is arranged in the wheel guard 1, and the rack 3 is slidably connected to the rack sliding track 102. A gear limiting mounting hole 103 is arranged in the wheel guard 1, and the gear 4 is rotatably arranged in the gear limiting mounting hole 103. The bottom of the rack 3 is provided with a protrusion as a sliding block 301 slidably connected to the rack sliding track 102. The back side of the rack 3 is provided with an insertion block 302 inserted into the sliding plate gear 501 of the sliding plate 5.
