description A rotary-to-linear lifter for fastener driving tools is provided that has independently movable lifter pins that lift a driver with driver protrusions during a lift stroke. The lifter includes a central lifter shaft that rotates during a lift stroke, a solenoid that actuates, a plurality of lifter pins, and a lifter base. When the solenoid actuates, the lifter pins protrude from the top of the lifter base, and when not actuated, the lifter pins retract inside the lifter base. Each lifter pin has a set of forward and rearward springs that allow for longitudinal pin movements along the lifter's axis of rotation. If there is interference during a lift stroke, individual lifter pin(s) become blocked, and mostly remain inside the lifter base, until the lifter rotates the affected pin away from the interference. Then that lifter pin will again protrude from the lifter base, ready to engage the driver protrusions.
