Removable contact trip assembly

摘要

A screwdriving tool (10) that includes a driving tool (driver) (12), a sensor (42), a sensor target and a contact trip assembly (14) that is coupled to the driving tool and has a nose element (72). The driver (12) has a housing (20), a motor (22) and an output member (28) that is driven by the motor. One of the nose element (72) and the output member (28) is axially movable and biased by a spring (76) into an extended position. The sensor (42) and sensor target are configured to cooperate to permit the sensor to provide a sensor signal that is indicative of movement of the one of the nose element (72) and the output member (28). The motor is controllable in a first operational mode and at least one rotational direction based in part on the sensor signal.
