DEVICE FOR DRIVING POWDER POWER OPERATED TYPE FIXING TOOL

PURPOSE: To suggest an explosive force operated fixing tool driving device which has a structure capable of suggesting propulsion reaction and is capable of easily performing a standard supply of a cartridge up to a moving shaft line by a conventionally simple method, even if the cartridge is the one of a magazine. CONSTITUTION: This explosive force operated fixing tool driving device has a barrel 11 capable of displacing in a shaft line direction within a housing 1 and a closing member 17. The housing 1, the barrel 11 and the closing member 17 are provided with abutting members 3a, 17e cooperating each other and shoulder parts 8b, 11e. By these members, the displacement of the barrel 11 is limited at first and the displacement of the opposite direction of a driving direction of the closing member 17 is limited according to advancing of the displacement. As a result, free space allowing a standard supply of a cartridge 15 of a magazine to a traveling shaft line, in particular, is generated between the barrel 11 and the closing member 17.
