Depth adjustment mechanism

摘要

A fastening tool (10) with a housing (12), a nosepiece (16) that is coupled to the housing (12) and a contact trip (20) that includes a lower contact trip (50), an upper contact trip (54) and a depth adjustment assembly (52). The lower contact trip (50) is mounted on the nosepiece (16) for translation between an extended position and a retracted position. The upper contact trip (54) is separate from the lower contact trip (50). The depth adjustment assembly (52) includes a stem (70), a sleeve (72) that is threadably coupled to the stem (70), and a knob (74). The knob (74) is rotatably coupled to the sleeve (72) but axially movable thereon. The stem (70) is coupled to one of the lower contact trip (50) and the upper contact trip (54) and the sleeve (72) is captured by the other one of the lower contact trip (50) and the upper contact trip (54). <IMAGE>
