  • Patent number: 10639779
    Abstract: A magazine assembly and a stapler including the same are provided. The magazine assembly includes a base and a rail assembly. The base has a first end portion and a second end portion. A direction from the second end portion toward the first end portion is defined as a first direction. The rail assembly is disposed on the base and adapted for a staple unit to movably abut thereagainst along the first direction. The rail assembly includes a first rail and a second rail which are separate. A first side wall of the first rail has at least one guiding portion extending in the first direction. Each guiding portion is adapted for a head of a T-shaped staple to slidably engage therewith along the first direction. The second rail is adapted for a U-shaped staple to abut thereagainst.

  • Publication number: 20180318994
    Abstract: The elastic stapler includes a main body, a striking device, a switch structure, and an elastic guiding element. The main body has a front opening and a working platform below the front opening. The striking device is arranged in the receiving space and has a movable striking mechanism. The switch structure is connected to the striking device. When a papersheet is inserted into the front opening of the main body to trigger the switch structure, the striking mechanism moves downward to strike a nail out. The elastic guiding element is arranged at the front opening of the main body. When the striking mechanism moves downward, the elastic guiding element abuts against the papersheet, and the elastic guiding element is compressed to bring the papersheet inward.

  • Publication number: 20180318995
    Abstract: The electric stapler includes a main body, a striking device, a pivot element, and a switch. The main body encloses a receiving space and has a front opening. The striking device is arranged in the receiving space and includes a movable striking mechanism. An end of the pivot element is pivotally connected to the striking mechanism, and an other end of the pivot element has a pressing portion. The switch is arranged in the receiving space of the main body and is connected to the striking device. The striking mechanism is driven to move to a striking position to strike a nail out when the switch is triggered. The switch is triggered when the pressing portion is pushed toward the switch by a papersheet.

  • Publication number: 20180178365
    Abstract: The electric stapler includes a main body, a striking device, a photoelectric switch, a pivot element, and a triggering element. The striking device arranged in the main body includes a movable striking mechanism. The striking mechanism tends to stay at an original position. The photoelectric switch is connected to the striking device. An end of the pivot element is pivotally disposed on the main body, and the other end has a pushing portion. The pivot element tends to stay at a first position due to an elastic means. The triggering element movably arranged between the photoelectric switch and the pushing portion tends to stay at a reset position. When an abutting portion of the pivot element is pushed by papersheets, the pivot element pushes the triggering element to a triggering position, and the photoelectric switch is triggered so that the striking mechanism strikes a nail out.
