The clamping mechanism includes a top plate, a bottom plate, a side plate, a second circular tube, and a nut. The edges of the top plate, bottom plate, and side plate are connected to form a C-shaped structure. The second circular tube is fixed on the bottom plate, with one end extending beyond the side plate. The second circular tube has an external thread, and the nut is fitted onto the second circular tube. The outer diameter of the second circular tube is not greater than the inner diameter of the first circular tube. There are multiple clamping mechanisms, and both ends of the first circular tube are inserted into the first circular tubes of two clamping mechanisms.

At the same time, it improves the protection effect on the operator, thus improving the practicality of the protective mechanism.

[0028] In this embodiment, the threaded rod 4 penetrates the interior of the upright plate 2 and extends to both sides of the upright plate 2. The threaded rod 4 is movably connected to the upright plate 2, which facilitates the movement of the connecting plate 7 and the limiting block 8.

[0030] Based on Embodiment 1, a preferred embodiment of the safety protection mechanism for pre-reserved openings in buildings provided by this utility model is, for example... Figures 1 to 4 As shown: A groove 10 is provided on one side of plate 1, and a slider 11 is movably connected inside the groove 10. Plate 2 12 is fixedly connected to one side of slider 11. A limit rod 13 is fixedly connected to the front of plate 2 12. A mounting plate 14 is movably connected to the outer wall of the limit rod 13. A fixing bolt 15 is movably connected to the front of the mounting plate 14. This facilitates the quick assembly, disassembly and splicing of the protective mechanism, improves the efficiency of assembly, disassembly and splicing, reduces the workload of operators, and facilitates subsequent transportation.

[0031] In this embodiment, the shape and size of the slide groove 10 and the shape and size of the slider 11 are matched with each other, and the plate 1 is movably connected to the plate 2 12 through the slide groove 10 and the slider 11, which facilitates the quick docking of the plate 1 and the plate 2 12.
