摘要:
A fastener-driving tool (10) includes an integrated function member (50) that performs at least two of the following three functions: a check pawl function, a last fastener-retaining function, and a dry fire lock-out function. In the disclosed embodiment, the integrated function member is provided as a lever-type structure that constitutes part of the access door assembly by means of which access is gained to the fastener drive track (31) along which fasteners (e.g., roofing nails) are fed to the driving portion of the tool. Also disclosed is an improved method of retaining the last nail in the drive track by a lateral head gripping action and a tool for performing the method.
摘要:
An adjustable annular exhaust air directing member (120) having a radially extending exhaust air outlet (122) is disposed in communicating relation with the exhaust opening (66) allowing air displaced into the exhaust opening (66) during the return stroke of the piston assembly (20) to communicate with the radially extending exhaust opening (122). Mounting structure (130, 132) serves to mount the exhaust air directing member on the frame structure (12) above the main valve assembly (38) for free rotational movement about the axis of the cylinder (18). A pair of O-rings are provided which act between the exhaust air directing member (120) and the frame structure (1) to ensure that air displaced into the exhaust opening (66) is discharged into the atmosphere through the radially outwardly extending exhaust outlet (122) in a direction determined by the rotational position of the exhaust air directing member in any rotational position into which it is manually moved.
