Buffer protection device

A buffer protection device relates to the technical field of mechanical buffer equipment. The buffer protection device comprises a supporting plate, a buffer energy absorption mechanism and a pressed block arranged above the supporting plate, the buffer energy absorption mechanism comprises a fixing plate fixed to the supporting plate, and a trapezoidal sliding groove is formed in the fixing plate; a cutting sliding block which can move from the end with the larger groove width to the end with the smaller groove width and extrude and cut the side wall of the trapezoidal sliding groove is arranged in the trapezoidal sliding groove, and the pressed block is connected with the cutting sliding block through a connecting rod mechanism. The buffer protection device is compact in structure, force in the vertical direction is mainly converted into force in the transverse direction, so that the whole device is thinner and smaller in size, the overall mass can be lighter, the buffer protection device can be directly in
