An anvil piece of a stapler is provided, including a main body, a crimp groove unit recessed on the main body and including at least one crimp groove, and an export unit. Each said crimp groove is for receiving a leg of a staple and has a blocking face which extends along a guiding path, and each said blocking face is for blocking the leg and making the leg bend along the guiding path; the export unit is recessed on the main body and communicates with the crimp groove unit on an extraction direction, the extraction direction is transverse to the guiding path and away from the crimp groove unit, the export unit includes at least exporting groove, each said exporting groove has an exporting face, and each said exporting face is for the leg which is bent to abuttingly slide therealong.

The present disclosure discloses a stapling device, comprising an activation unit configured to sense at least one of a movement of the stapling device, a position of a switch or a signal from a timer. There is a detection unit that is activated based on a signal from the activation unit to generate an input data. The stapling device further comprises a processing unit to determine number of pins in the stapling device, by comparing the input data with a pre-configured data and a display unit interfaced with the processing unit, to indicate status of the pins in the stapling device, wherein the status is based on the determined number of pins in the stapling device. Thus the stapling device of the present disclosure identifies the exhaustion of pins and accordingly enables timely replenishment of the stapling device with pins.

A stapling device extends in a longitudinal direction from a front region to a rear region, having a bottom part having a set-down surface on its underside, having an anvil leg that is mounted so as to be pivotable in a limited manner about a first pivot pin in the front region with respect to the bottom part and carries an anvil plate in the front region, having a staple magazine that is mounted on a bearing block in the rear region so as to be pivotable in a limited manner about a second pivot pin with respect to the anvil leg, having a driver leg that is mounted so as to be pivotable in a limited manner about the second pivot pin with respect to the anvil leg and with respect to the staple magazine and has a driver for guiding staples through a gap at the front end of the staple magazine and for pressing the staples against the anvil plate, and having at least one longitudinally extending lever which is mounted on the bottom part by means of a first bearing in the rear region and on the anvil leg by a second bearing between the front region and the rear region, wherein one of the bearings is a third pivot pin and the other bearing is a floating bearing, and wherein the at least one lever is coupled to the driver leg, at the front, end of the lever facing the front region, such that a movement of the front end towards the anvil leg results in a movement of the driver towards the anvil plate.

A stapler includes a staple striking-out unit, a staple leg bending unit, and a connector that connects the staple striking-out unit and the staple leg bending unit. The staple leg bending unit includes a clincher having a guide surface for bending the staple legs, and a clincher guide having a sandwiching portion. The clincher guide is configured to move in a first direction to displace a distance between the guide surface and the sandwiching portion. The clincher is capable of being located at a lower end position where the guide surface is farthest from the sandwiching portion in the first direction. The lower end position is a position where a tip ends of the staple legs are in contact with the guide surface and a gap is formed between an upper surface of the sheet sandwiched by the sandwiching portion and a staple shoulder portion of the staple.

A flat clinch assembly fits upon or within a base of a stapling device. The assembly preferably includes a slot with extended resiliently biased arms or toggles, where a rest position has the arms at or near a level of a working surface. An ejecting staple deflects and energizes the arms to cause the arms to rotate and create a clearance recess whereby points of the staple legs slide inward along the anvil. A restorative bias acting on the arms causes the arms to rebound to a rest position and to bend the legs upward. The legs thereby are normally pressed flat against the back sheet of a paper stack at the working surface. The arms or toggles are lightweight whereby the inertia of a fast-moving staple moves the arms or toggles. The toggle may include an upward facing staple leg guide channel.

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 sheet processing apparatus is provided with an operation member and an motion member that rotates with a force of the operation member through the connection part and applies force to an acting member. A fulcrum of a rotating operation of the operation member moves depending on an operation of the operation member. A first length between the fulcrum and a part at which the operation member is applied with the force and a second length between the fulcrum and a part at which the force is applied from the operation member to the motion member are changed.

A device functioning as a stapler. The device including a viewing region within an arm of the stapler. The viewing region adapted to provide a user of the device with a view of an interior of a magazine within the arm of the stapler, wherein a user of the device can determine the amount of staples within the magazine without having to open the device. The device further includes an integrated staple removal tool received within a base portion of the device.

A stapler structure contains: a base, a stapling mechanism and a press block which are connected with a connector. The stapling mechanism includes an elastic sheet and a trigger portion accommodating a control column which has a horizontal stein. An accommodation seat connects with a rotation member and a guiding groove having a through trough, and the accommodation seat houses a locking sheet having two raised ribs, and a coupling plate is joined with the accommodation seat and has a recess. The rotation member has a hollow chamber, an elongated orifice, and multiple fixing orifices. A movable adjuster has a first protrusion and a coupling shaft configured to connect a second protrusion with the first protrusion, a first positioning post is inserted into the elongated orifice, a second compression spring is accommodated in the hollow chamber, and a C retaining ring retains with the second compression spring.
