Powered fastener driver

A fastener driver comprising:

• a magazine configured to receive fasteners, the magazine having a length extending between a first end and a second end, the magazine including a latch member positioned proximate the second end;
• a nosepiece including a fastener driving channel from which consecutive fasteners from the magazine are driven, the nosepiece coupled to the first end of the magazine;
• a pusher slidably coupled to the magazine, the pusher including a body and a lever movably coupled to the body, the body configured to contact one of the fasteners for biasing the fasteners toward the nosepiece, the lever including a first end and a second end opposite the first end;
• and
• a spring configured to bias the first end of the lever away from the body of the pusher,
• wherein the first end of the lever is configured to selectively engage with the latch member when the pusher is moved toward the second end of the magazine for retaining the pusher in a rearward position, and wherein the second end of the lever is movable by a user for releasing the engagement between the first end of the lever and the latch member.

A powered staple driver comprising:

• a magazine including a rail defining an edge portion and two opposed sidewalls adjacent the edge portion, the magazine configured to receive a strip of collated staples straddling the edge portion and the sidewalls of the rail;
• a pusher slidably coupled to one of the sidewalls of the rail;
• and
• a support member coupled to the pusher for movement therewith,
• wherein the support member straddles the edge portion and the sidewalls of the rail to engage the strip of collated staples supported upon the edge portion of the rail.

• a nosepiece including a staple driving channel from which consecutive staples from the magazine are driven, the nosepiece coupled to the first end of the magazine;
• a pusher slidably coupled to the magazine, the pusher including a body, a first pawl proximate a first of the sidewalls and coupled to the body, and a second pawl proximate a second of the sidewalls and coupled to the body, the first and second pawls configured to bias the staples toward the nosepiece;
• and
• a first spring and a second spring configured to bias, respectively, an end of each of the first pawl and the second pawl toward the first and second sidewalls,
• wherein the end of each of the first pawl and the second pawl is movable away from the first and second sidewalls, respectively, in response to the pusher being moved toward the second end of the magazine.
