The invention relates to a stapling device (10, 10), comprising: an anvil leg (12), which bears, in its front region (16), an anvil plate (18); a staple magazine (24), which can be pivoted to a limited extent relative to the anvil leg (12) about a transverse axis (22) located in the rear region (20) of the anvil leg (12); a driver (30) for carrying out stapling through a gap (28) at the front end (26) of the staple magazine (24), said gap being located above the anvil plate (18); and an actuation apparatus (34) for acting upon the driver (30) toward the anvil plate (18) against the restoring force of a driver spring (48); wherein the actuation apparatus (34) has a solenoid (36) and a striking pin (40) for acting upon a driver anvil (46) fixedly connected to the driver (30), the striking pin being movable by means of the magnet coil (36), and wherein, between the gap (28) and the transverse axis (22), the staple magazine (24) is supported on the anvil leg (12) by means of a magazine spring (50). According to the invention, the magazine spring (50) is dimensioned such that, in the absence of external forces, the staple magazine (24) lies on the anvil leg (12) or on the anvil plate (18).

A device for automatically offsetting pronged fasteners, or staples, in successively fastened sets of sheet material is provided. The assembly may be disposed within any manual or power driven stapler. It may comprise a manually or electrically rotatable drive gear which, when rotated, pushes a means for setting the depth at which such fasteners may be delivered into such sheet material respective to an edge thereof. In use, stacked sheets of material, such as paper, may be placed within a stapler. Then, when the stapler is activated to fasten the set, the drive gear may automatically rotate to push the means for setting the depth forward so that a subsequently delivered fastener may be delivered into a following set of sheet material at a different depth from the edge of the prior set.

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.

Stapler (1) for driving staples (4) into a workpiece (6), comprising a body (2), an elastic member (7) connected to a driver (9) and an articulated arrangement (12) for tensioning of the member (7) comprising a lever (13) with a long arm (15) and a short arm (16) coupled rotatably to the body by a first coupling shaft (14), an articulated arm (17) coupled rotatably to the body by a second coupling shaft (18) and connected to the member (7) in a force-influencing manner, an intermediate joint (19) with a third coupling shaft (20) assigned rotatably to the short arm (16) at a first distance (a) from the first coupling shaft and assigned rotatably to the articulated arm (17) with a fourth coupling shaft (21) at a second distance (b) from the third coupling shaft (20), the first distance has the distance line (a) and the second distance has the distance line (), which form the angle () between themselves, the member (7) is tensioned in that the lever (13) is rotated (N) about coupling shaft (14) from a starting position to an end position, due to which the lever via the intermediate joint causes the articulated arm to rotate (R) about the coupling shaft and tension the member (7) by guiding this from a first neutral untensioned position to a second tensioned position, wherein the first distance (a) is 1.2-1.6 times greater than the second distance (b).

A stapling device includes an anvil leg, an anvil plate, a staple magazine, which can be pivoted relative to the anvil leg about a transverse axis, a driver for carrying out stapling through a gap at the front end of the staple magazine, and an actuation apparatus for acting upon the driver toward the anvil plate. The actuation apparatus has a solenoid and a striking pin for acting upon a driver anvil fixedly connected to the driver, the striking pin being movable by the solenoid. Between the gap and the transverse axis, the staple magazine is supported on the anvil leg by a magazine spring. The magazine spring is configured such that the staple magazine rests on the anvil leg or on the anvil plate due to a force of gravity acting on the staple magazine and overcoming a spring force of the magazine spring.
