The invention discloses an energy-saving environment-friendly material brick cutting device. The energy-saving environment-friendly material brick cutting device comprises a base. Supporting rods aresymmetrically arranged on the two side edges of the top end of the base. A transverse rod is arranged at the top ends of the supporting rods on the two sides. A hinge is arranged at the middle portionof the bottom end of the transverse rod. A supporting frame is arranged at the bottom end of the hinge and is an inverted-U-shaped supporting frame. A bottom plate is arranged at the bottom end of one side of the supporting frame. The bottom plate and the supporting frame are connected through a movable shaft. A motor is arranged at the top end of the bottom plate. The end, away from the movableshaft, of the bottom plate is provided with a first connecting rod. The end, away from the bottom plate, of the first connecting rod penetrates the supporting frame. The end, close to the first connecting rod, of the supporting frame is internally provided with a first sliding port matched with the first connecting rod. The end, away from the bottom plate, of the first connecting rod is provided with a first limiting column. The outer side of the end, close to the first limiting column, of the first sliding port is provided with a plurality of limiting grooves. A second connecting rod is arranged at the top end of the side, close to the first connecting rod, of the supporting frame. A fixing rod is arranged at the bottom end of the side, close to the second connecting rod, of the transverse rod, and the second connecting rod penetrates the fixing rod.
