This application relates to an auxiliary tooling for preventing the tipping of a guard plate, comprising multiple auxiliary mechanisms installed around the periphery of the guard plate. These auxiliary mechanisms are spaced apart. Each auxiliary mechanism includes a vertical rod parallel to the height direction of the guard plate. A fixing plate and a sliding plate perpendicular to the fixing plate are mounted on the vertical rod. The sliding plate is fixedly connected to the vertical rod. A fixing bolt is threaded onto the fixing plate. Threaded holes are formed around the periphery of the guard plate, and the fixing bolt passes through the fixing plate and is threaded into the threaded holes. This application effectively prevents the guard plate from tipping over, causing injuries or other safety hazards.
