Efficient crushing movable jaw of jaw crusher

The invention relates to the technical field of jaw crushers, in particular to an efficient crushing movable jaw of a jaw crusher. An efficient crushing movable jaw of a jaw crusher comprises a movable jaw frame body, an extrusion part and an efficient crushing part, the extrusion part is rotationally connected with the movable jaw frame body, the efficient crushing part is arranged between the extrusion part and the movable jaw frame body, and the efficient crushing part is movably connected with the extrusion part. According to the jaw crusher, the placement groove is formed in the front side of the movable jaw frame body, the efficient crushing part is arranged in the placement groove, the to-be-crushed object is extruded through the extrusion part, and when the to-be-crushed object is not prone to being crushed, the to-be-crushed object is extruded through the efficient crushing part, so that the crushing efficiency of the jaw crusher can be greatly improved. 本发明涉及颚式破碎机技术领域，具体地说就是一种颚式破碎机高效破碎动颚。一种颚式破碎机高效破碎
