Mounting structure for graphite brush

The utility model discloses a mounting structure for a graphite electric brush, which relates to the technical field of graphite electric brushes and comprises a fixing plate, a graphite electric brush body is arranged on one side of the fixing plate, a conical groove is arranged in the graphite electric brush body, and a guide hole penetrating to the outer side of the graphite electric brush body is arranged on one side of the conical groove. The butt joint sleeve is inserted along the guide hole, one end of the butt joint sleeve extends to the inner bottom face of the conical groove, then the adjusting knob is rotated, the threaded column is made to rotate, and therefore the conical block is driven to slide in the butt joint sleeve. When the conical surface of the conical block is attached to the inclined surface on the inner wall of the wedge-shaped block, the wedge-shaped block is extruded towards the outer side, so that the inclined surface on the outer side of the wedge-shaped block is attached to the i
