Abstract
A fastening tool with a housing, a nosepiece that is coupled to the housing and a contact trip that includes a lower contact trip, an upper contact trip and a depth adjustment assembly. The lower contact trip is mounted on the nosepiece for translation between an extended position and a retracted position. The upper contact trip is separate from the lower contact trip. The depth adjustment assembly includes a stem, a sleeve that is threadably coupled to the stem, and a knob. The knob is rotatably coupled to the sleeve but axially movable thereon. The stem is coupled to one of the lower contact trip and the upper contact trip and the sleeve is captured by the other one of the lower contact trip and the upper contact trip.
Claims22
A fastening tool comprising:
- a housing;
- a nosepiece coupled to the housing;
- and
- a contact trip having a lower contact trip, an upper contact trip and a depth adjustment assembly, the lower contact trip being mounted on the nosepiece for translation between an extended position and a retracted position, the upper contact trip being separate from the lower contact trip, the depth adjustment assembly including a stem, a sleeve, and a knob, the stem being threadably coupled to the sleeve, the knob being rotatably coupled to the sleeve but axially movable thereon, wherein the stem is coupled to one of the lower contact trip and the upper contact trip and wherein the sleeve is captured by the other one of the lower contact trip and the upper contact trip.
A fastening tool comprising:
- a housing;
- a nosepiece coupled to the housing, the nosepiece;
- and
- a lower contact trip that is configured to translate relative to the nosepiece;
- an upper contact trip that is separate from the lower contact trip;
- and
- a depth adjustment assembly for adjustably coupling the lower contact trip and the upper contact trip, the depth adjustment assembly including a stem, a sleeve, a knob and an adjustment housing, the stem having a threaded adjustment portion and an attachment portion that is removably coupled to one of the lower contact trip and the upper contact trip, the threaded adjustment portion of the stem being threadably engaged to the sleeve, the sleeve including a pair of flanges that are disposed between opposite end walls of the other one of the lower contact trip and the upper contact trip, the knob including a central aperture having a non-circular shape that corresponds to at least a portion of the sleeve to rotatably couple the knob and the sleeve but permit the sleeve to translate axially through the knob, the adjustment housing being coupled to the housing and axially capturing the knob, the adjustment housing carrying at least one deflectable member that is movable between a first position, which inhibits free rotation of the knob, and a second position, which permits the knob to be manually rotated.
