摘要

FIELD: machine building.SUBSTANCE: invention relates to set tool for anchor to be fitted at insulation material dowel base. Set tool comprises first drive shaft. Said shaft has the rod extending along lengthwise axis with the first dog for torque transmission to fastener at first end and second dog torque transmission to set tool at second opposite end. It comprises second drive shaft arranged coaxially with the first drive shaft. Said second shaft has hollow rod with the third torque transmission dog at first end and clutch released by axial pressure. Said clutch is located in one area at a distance to first end of the second drive shaft and comprises at least one locking element. Said locking element interacts with at least one recess to transfer torque from first drive shaft to second drive shaft. One groove is made to direct said locking element. Said groove adjoins said recess and extends at least in spiral in direction of first drive shaft second end.EFFECT: simplified clutch disengagement.7 cl, 4 dwg
