Existing protective nets are prone to tilting or even collapsing under stress, and their connection to the ground is not secure enough.
By setting a support assembly on the protective plate, including a plate and a support rod, the plate contacts the ground to provide support, the support rod is slidably connected to the protective plate, and a serrated structure is formed on the plate to increase friction. The support rod is fixed by locking bolts, and a sleeve and vertical shaft are installed on the column for easy connection.
This effectively prevents the protective plate from tilting or falling over under stress, thus improving the stability and protective effect of the protective device.
