摘要 |
A fastener driving tool for an insulation material plug that anchored with a fastener in the substrate has a first drive shaft and a second drive shaft. The first drive shaft has a shank extending along a longitudinal axis having a first rotary carrier for the fastener at a first end and that has a second rotary carrier second end. The second drive shaft has a hollow shank with a third carrier means for the insulation material plug at a first end. A coupler is provided that can be disengaged by axial pressure and arranged at a distance from the first end. The coupler has locking elements that engage into recesses in order to transfer a torque from the first drive shaft to the second drive shaft. Grooves guide the locking elements are adjacent to a recess and, extend helically along the circumference. |
