Safety protection device of hydraulic packing machine

The safety protection device comprises a base, the upper end of the base is fixedly connected with a fixing frame, the upper end of the fixing frame is fixedly connected with two symmetrically-arranged telescopic air cylinders, and the telescopic ends of the two telescopic air cylinders both penetrate through the upper end of the fixing frame and are jointly and fixedly connected with a pressing plate; the pressing plate is slidably connected to the inner wall of the fixing frame, a protection plate is arranged at the front end of the fixing frame, a rotating groove is formed in the front end of the fixing frame, and a rotating mechanism used for rotating the protection plate is arranged in the rotating groove. The power motor drives the rotating shaft to rotate, under the meshing effect of the two bevel gears, the rotating rod rotates, the rotating rod rotates to drive the connecting block on the outer wall of the rotating rod to rotate, and therefore the connecting block drives the protection plate to rotat
