[0011] When the upper and lower mesh protective covers are installed, the personnel pull out the cover plate and unfold the two unfolding rods, and a triangle is formed by the two unfolding rods and the cover plate. The mounting posts on the upper and lower mesh protective covers are inserted into the mounting holes of the two unfolding rods and the cover plate, which improves the stability of the installation of the upper and lower mesh protective covers. When the mounting posts enter the limiting slots, the limiting plug rods will move right. When the limiting slots on the mounting posts and the limiting plug rods are in the same horizontal position, the limiting plug rods can be restored by the elastic force of the springs to allow the limiting plug rods to enter the limiting slots, thereby limiting the position of the mounting posts, so that the upper and lower mesh protective covers are installed on the outer wall of the swing arm to protect the rotor. When the upper and lower mesh protective covers need to be removed, the personnel press the push rod to move the limiting plug rod right out of the limiting slots, which facilitates the separation of the mounting posts from the mounting holes, thereby allowing the upper and lower mesh protective covers to be quickly disassembled and assembled, the operation is simple, and the disassembly and assembly efficiency of the anti-collision device is improved.
