Concrete fracture resistance testing machine

The utility model relates to the technical field of concrete, in particular to a concrete fracture resistance testing machine. The problem that spacing adjustment operation is complex is solved. The device comprises a base, a containing cavity is formed in the base, a hanging bracket is arranged on the base, a linear module is arranged at the top end of the hanging bracket, the linear module is longitudinally arranged, the output end of the linear module faces the base and is connected with an anti-bending plate, and a plurality of anti-bending bodies are arranged on the bottom face of the anti-bending plate. A moving mechanism for driving at least one anti-bending body to move is further arranged on the anti-bending plate, the bottom ends of the anti-bending bodies are arranged at the same height, and the anti-bending bodies are located over the containing cavity. According to the utility model, a workpiece is extruded by the anti-bending ball, so that different anti-bending test requirements can be met, the
