fastener driving tool

摘要

The device has a spring (200) e.g. helical spring, storing mechanical energy, an energy transfer member movable between an original position and a setting position for transmission of energy from the spring to a fastening part. An energy transmission unit i.e. piston, transmits energy from a power supply to the spring. A force transmission device i.e. roller traction unit (260), transmits force from the transmission unit to the spring. The force transmission device and the energy transmission unit are mutually impacted with force while the transfer member transfers energy to the part. The energy transmission unit is designed as a linear output unit i.e. spindle nut, and/or a rotary drive or piston (100), and comprises a tape (270) that is made of core of plastic fibers.
