| 20090045240 | Stapler - A stapler has a center of gravity and has a base assembly, a magazine assembly and a trigger assembly. The magazine assembly connects to the base assembly and has a cap. The trigger assembly connects to the base assembly and has a trigger lever and a limiting lever. The limiting lever prevents the trigger lever and the cap from pivoting excessively to keep the center of gravity of the stapler over the base assembly so that refilling the stapler is convenient. | 02-19-2009 |

| 20110248066 | HAMMER TACKER - A hammer tacker of the present invention includes a shell, a receiving tank, a magazine and a switch. The shell defines an inner chamber, and it includes a handle and a head which has a bottom opening. The receiving tank defines a space and has an opening facing downward, which communicates the bottom opening of the head. The magazine is slidably received in the receiving tank, and the magazine has a bottom surface on which a retaining slot is formed. The switch is pivotably disposed on the bottom of the shell. The switch has a press portion and a retaining portion, from which a retaining protrusion is extended. The retaining protrusion selectively engages with the retaining slot to prohibit the movement of the magazine. When the press portion is pressed, the retaining protrusion disengages from the retaining slot so that the magazine becomes slidable. | 10-13-2011 |
| 20120061444 | LABOR-SAVING STAPLER - A labor-saving stapler of the present invention includes a base, a press arm, a transmission arm, a connection arm, a magazine, a staple pusher, a moving means, a buckling means and a switching means. The magazine is slidably disposed between the connection arm and the base. The moving means moves the magazine outwardly when the switching means is activated. As such, the magazine can be opened by operating the switching means. When the switching means includes a button or the same, users can open the magazine easily with only one hand. | 03-15-2012 |
| 20140021237 | SPRING BIASED LOCK FOR MAGAZINE OF NAIL GUN - A magazine of nail gun is provided with a nail receptacle; a cover slidably mounted on the receptacle; a cavity on an uneven bottom of the cover; a first hole from the cover to the cavity; a spring biased button in the first hole; a first retaining member secured to the button and urging against a bottom of the cavity so as to retain the button; a second hole through the receptacle and aligned with the first hole; a spring biased detent in the second hole and projecting out of the second hole to urge against a bottom of the button; and a second retaining member secured to the detent and urging against the bottom of the receptacle so as to retain the detent. The cover is locked by the receptacle in a storage position of the magazine. | 01-23-2014 |
| 227128000 | Pivoted magazine cover | 7 |
| 20080308598 | Stapling device - A stapling device includes a housing and a cover pivotally attached to a base member, a staple drive plate received in the housing for staple driving purpose, a lever attached in the housing and engaged between the staple drive plate and the cover, a spring for biasing the cover away from the housing, a spring device attached to the housing for biasing the staple drive plate, and a follower slidably received in the housing for selectively latching the cover to the housing and for preventing the cover from being moved and depressed toward the housing when the housing and base member are rotated away from each other and for preventing the staple drive plate from being triggered or actuated inadvertently. | 12-18-2008 |
| 20100264190 | Effort-saving Stapler - An effort-saving stapler comprises a base member defining a coupled member; a magazine assembly having a first end pivotally connected to the coupled member and a second end; a linkage assembly which has a first end and a second end including a pair of first slide grooves defined at the first end thereof, a pair of channels defined at the second end thereof, a pair of second slide grooves defined between the first and second ends thereof and a firing member slideably coupled to the channel and being able to drive the second end of the magazine assembly; a lever arm which has a first end slideably coupled to the first slide grooves of the linkage assembly and a second end including a pair of third slide grooves between the first and second ends thereof, with the second and third slide grooves slideably joined together and selectively engaged with the coupled member of the base assembly, and with the lever arm pivotally coupled to the coupled member between the first end of the lever arm and the third slide grooves. | 10-21-2010 |
| 20110031295 | MAGAZINE FRONT END RETAINING STRUCTURE FOR HAMMER TACKER - A magazine front end retaining structure for hammer tacker includes a case body head cap connected to a front end of a case body of a tacker case of the hammer tacker; a retaining push member pivotally mounted to a front opening of the case body head cap; an outer staple channel head cap connected to a front end of an outer staple channel of a magazine, which and a magazine cover are coaxially pivotally connected at respective rear end to a rear end of the case body, and a catch section located at a front end of the outer staple channel head cap for the retaining push member to hook thereto, so that a front end of the magazine is held to the tacker case. To release the front end of the magazine from the tacker case for loading staples, simply pushes the retaining push member with one hand. | 02-10-2011 |
| 20110233256 | SPRING ACTUATED PLIERS STAPLER - A spring-energized stapler having a pliers type configuration, wherein papers and like items are fastened at a front end and the stapler is normally gripped and squeezed at a rear end. A compact mechanism and independent handle linkages provide a compact overall shape in a high efficiency action. An upper handle is pivoted at a front, top of a housing with a pressing area spaced at least one half the handle length away from the upper handle pivot. A lower handle includes a multi-segment cam link to a base to provide a minimal gripping distance with a large clamping force at an anvil. A simplified front-loading mechanism provides a compact, low cost assembly. A release latch holder is located behind the striker for a compact front end. | 09-29-2011 |
| 20110309126 | MID-ZONE STAPLER or PRESSING TOOL - The mid-zone pressing tool has a base and a pressing assembly, which are pivotally connected at the rear by a transverse shaft. A pair of cantilevers extends forward from each side of an uppermost rear portion of the base. A pair of arms is connected on the distal ends by a common handle. A first coupling connects a middle portion of each arm to the pressing assembly by an axle, cam or link. A second coupling connects the proximal ends of each arm to the cantilever by an axle, cam or link. Pushing the handle down pivots the arms, engages the couplings, and transmits a concentrated downward force to the front of the pressing assembly. The cantilevers allow a range of coupling placements, including near the middle of the pressing tool. The couplings are optionally releasable. | 12-22-2011 |
| 20120286015 | STAPLER - A stapler comprises a securing member comprising a base and a securing plate perpendicular to the base, the base comprising a stapling slot; the securing plate comprising a receiving slot and a separating portion in the receiving slot; the receiving slot being divided to first and second receiving portions by the separating portion; a staple tray receives staples and comprising a pivoting shaft and a through hole aligned with the stapling slot; a pressing member comprising a protruding portion; a first resilient member attached to the pressing member, the first resilient component comprising a driving piece; wherein the pressing member is rotatably engaged with the securing plate through the pivot shaft; when the pressing member is rotated towards the securing member, the protruding portion extends through the separating portion and slidably positioned in the second receiving portion, and the driving piece drives one staple through the through hole. | 11-15-2012 |
| 20120318840 | SPRING ACTUATED PLIERS STAPLER - A spring-energized stapler having a pliers type configuration, wherein papers and like items are fastened at a front end and the stapler is normally gripped and squeezed at a rear end. A compact mechanism and independent handle linkages provide a compact overall shape in a high efficiency action.
