Side slope anchoring device

The utility model relates to the technical field of side slope reinforcement, in particular to a side slope anchoring device which comprises a bottom plate and a side plate which are supported on a slope bottom and a slope surface correspondingly. One end of the bottom plate is rotatably connected with the bottom end of the side plate; an inclined supporting rod with the adjustable length is installed between the bottom plate and the side plate, one end of the inclined supporting rod is hinged to the bottom plate, and the other end of the inclined supporting rod is hinged to the side plate. A first anchor nail used for being anchored to the slope bottom is installed on the bottom plate, and a second anchor nail used for being anchored to the slope surface is installed on the side plate. In the process of stabilizing the side slopes with different gradients, a worker adjusts the length of the inclined supporting rod, so that the side plates are rotationally adjusted relative to the bottom plate to be attached
