A stapler includes a base, a handle pivotably connected to the base, and a magazine unit having a channel body which is pivotably attached to the base, a magazine body which is coaxially disposed to and movable relative to the channel body in a lengthwise direction, and a magazine ejection spring disposed to bias the magazine track to make an ejection movement. The magazine unit further has a damping module disposed on the magazine track and having two spring-biased damping members which are movable relative to the magazine track to be slidably moved on and frictionally engaged with inner wall surfaces of two outer lateral wails of the channel body so as to retard the ejection movement of the magazine track.

A driving tool comprises a tool main body that includes a driver for driving a U-shaped staple, and a main magazine for housing a plurality of staples that extends from the tool main body. The driving tool also comprises a sub-magazine to which a pusher and a staple guide are attachable. The pusher pushes the staples in the main magazine toward the tool main body. The staple guide is inserted between a pair of legs of the staple in the main magazine. The driving tool also comprises a guide mechanism for guiding the sub-magazine toward the tool main body from an opening position to a closing position with respect to the main magazine. The guide mechanism also guides the sub-magazine in a direction opposite to a driving direction while the sub-magazine moves from the opening position to the closing position.

A powered staple driver includes a magazine configured to receive staples and a nosepiece having a staple driving channel from which consecutive staples from the magazine are driven, the staple driving channel extending along a driving axis. The magazine obliquely extends from the nosepiece in both a first plane containing the driving axis and a second plane that is perpendicular to the driving axis.

A composite staple magazine for tackers includes a guide member, a receiving body, a support member, a push member, a resilient member and an end member. The receiving body is fixed to the guide member. The support member is made of plastic material and snapped to the receiving body. The support member includes two respective positioning portions which are engaged with the engaging portion of the receiving body. The resilient member is wrapped to the roller of the support member and connected to the push member which is slidably mounted to the receiving body. The resilient member pushes the staples forward. The end member is fixed by a bolt. The composite staple magazine is simple, easily assembled and saves cost.

A stapler comprises a base (1), a staple pin track (2), a top blade assembly (3), a hinge (4) and an upper cover (5). Tail ends of the staple pin track, the top blade assembly and the upper cover are all hingedly connected to a tail end of the base. A first guide part is disposed on a side wall of the upper cover, and one end of the hinge is slidably connected to the first guide part. The first guide part is set in a structure that when the upper cover is pressed, one end of the hinge can move to the tail end of the upper cover and press downwards. A second guide part is disposed on the side wall of the base, and the other end of the hinge is slidably connected to the second guide part. The second guide part is set in a structure that when the upper cover is pressed, the other end of the hinge can move to a front end of the base, and when the upper cover is opened, the other end of the hinge is separated from the base. A middle part of the hinge is hingedly connected to a middle of the top blade assembly, and the first guide part is close to the tail end of the upper cover. The present invention has a good labor-saving effect and makes it convenient to put in staple pins.

A stored energy stapler includes a base portion and a first lever pivotally coupled to the base portion. The first lever includes a front end and a back end. The stapler also includes a second lever pivotally coupled to the base portion about a pivot point, the second lever having a front end and a back end, and a striker element at the front end for driving a staple out of the stapler. The stapler also includes a torsion spring coupled to both the first lever and the second lever that biases the back ends of the first and second levers apart from one another. The pivot point is disposed between the striker element and the torsion spring.

The present invention consists of the complete integration of a self arming controlled action pneumatic fastener magazine slider (pusher and feeder) within the two legs of a stack of U-shape staples on a magazine support rail, thanks to the interplay of two pairs of releasably interlocking sensor and keys fastener pusher elements. In one embodiment of the invention, the slider system is self-arming and fits within an elbowed magazine for receiving fasteners, but works along the straight portion of the magazine. This slider system will accommodate elongated magazine holding a larger number of fasteners. The slider system will decrease the time required for fastener reloading by simplifying operations and enabling a greater flexibility for the operator. A fastener retention device may be provide to the fastener pusher, defining an operative mode active with a large storage load of fasteners into the magazine, and a inoperative mode triggered when the load of magazine feeders decreases below a threshold value.

A magazine structure of a wire staple press is disclosed, which involves an arrangement that a staple receiving compartment of a magazine cartridge forms therein a clamp passage, a first nail passage, and a second nail passage respectively corresponding to a clamp part, a U-shaped nail part, or a T-shaped nail part of a wire staple and the arrangement allows the staple magazine to be used with wire staples having a U-shaped nail part or a T-shaped nail part thereby improving the applicability of the wire staple press and allowing staples of different types to be fed in a stable manner to prevent the staples from curing during a striking operation and thus improving effectiveness and efficiency of operation and the utilization thereof.

A nail pushing device of a nail gun includes a base connected to the nose of the nail gun, a cover slidably connected to the base, and restriction units received in the cover. The base has multiple positioning slots, slide slots and passages. The restriction units are installed in the positioning slots and each have a main part for being contact with the nails. The main part of each restriction unit has a ridge protruding laterally therefrom and a resilient leg extends from each of two ends of the ridge. The restriction units each have a guide member and an engaging portion on two ends thereof. The restriction units located in the positioning slots at different positions are used to guide nails of different lengths.

A fastener driver includes a magazine having a latch member and a pusher slidably coupled to the magazine. The pusher includes a body and a lever movably coupled to the body. The body is configured to contact one of the fasteners for biasing the fasteners toward a nosepiece. The lever includes a first end and a second end opposite the first end. A spring is configured to bias the first end of the lever away from the body of the pusher. The first end of the lever is configured to selectively engage the latch member when the pusher is moved toward a second end of the magazine for retaining the pusher in a rearward position. 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.
