Zusammenfassung:	The utility model discloses a spiral shell rasp bar subassembly belongs to the mechanical manufacturing technology field. The utility model provides a spiral shell rasp bar subassembly can assemble the spiral shell rasp bar who forms different length including installation pole, connecting rod group and screw head, connecting rod group including the connecting rod of a plurality of different length, installation pole, connecting rod and screw head to improved spiral shell rasp bar's commonality in very big degree, be convenient for to the parts machining internal thread of different thickness.Through set up the guide part on the screw head, set up spacing portion between installation pole and connecting rod, improved the precision when spiral shell rasp bar processes the internal thread in very big degree. Be provided with the double thread through follow circumference on the outer wall of screw head, can directly process out the double thread, be favorable to putting forward high pressure heater work efficie
