[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. The embodiments described by referring to the drawings are exemplary, and are used for explaining the utility model, and cannot be understood as the limitation of the utility model.

[0019] The embodiments of the utility model will be described according to the overall structure of the utility model.

[0020] Please refer toFigure 1 - Figure 4 A protective device for a tractor cab window includes a positioning sleeve 1, a reinforcing rib 2 installed on the inner wall of the positioning sleeve 1, a positioning block 3 installed on the outer wall of the positioning sleeve 1, a fixing frame 4 installed on the inner wall of the positioning sleeve 1, a protective net 5 installed on the inner wall of the fixing frame 4, a limit spring 6 installed on the inner wall of the protective net 5, and a push rod 7 installed on the outer wall of the limit spring 6. The reinforcing ribs 2 are evenly distributed around the central axis of the positioning sleeve 1. The fixing frame 4 is inserted into the positioning sleeve 1. The side wall of the fixing frame 4 is designed with openings, and the push rod 7 is slidably connected to the through holes in the side wall of the fixing frame 4. The push rod 7 forms a telescopic structure with the fixing frame 4 through the limit spring 6, and the push rod 7 is engaged with the positioning sleeve 1. The system consists of a positioning sleeve 1, reinforcing rib 2, positioning block 3, fixing bracket 4, protective net 5, limiting spring 6, and top rod 7.
