摘要： A machine for driving fastening members into workpieces, comprising:
- a reversible drive motor (3);
- an axially displaceable tool (6); and
- a motion conversion mechanism comprising a screw rod (9) and a nut (10) which co-operates with the screw rod, for converting a rotary motion of the output shaft of the drive motor into an axial translational motion of the tool.
The nut is axially fixed to a holder unit (11) and is prevented from being displaced in the axial direction in connection with a mutual rotation between the screw rod and the nut, the screw rod being displaced in relation to the nut and the holder unit in the axial direction when the screw rod and the nut are subjected to a mutual rotation under the effect of the drive motor. The tool is arranged to be displaced together with the screw rod in the axial direction downwards into engagement with a fastening member when the screw rod and the nut are subjected to a mutual rotation in a first direction and in the axial direction upwards out of engagement with the fastening member when the screw rod and the nut are subjected to a mutual rotation in a second direction.
