摘要： A stapler comprises a stapling unit and a base movably connected to each other. The base comprises an anvil, a lower and an upper part with a contact surface which has a staple opening against which a workpiece is placed. The upper and lower parts are movably connected to each other. In operation, movement of the stapling unit and the base toward each other drives a staple into the workpiece, wherein the staple crown comes in contact with the workpiece and the staple legs extend through the staple opening. Upon movement of the upper part and stapling unit toward the lower part, the staple legs are bent by the anvil into contact with the underside of the workpiece. The anvil is attached to the base by an elastic element between the lower and upper part, and is urged toward the staple opening to block the opening when the stapler is in an initial position.

摘要： A stapler (1) for stapling together a workpiece (5), primarily a sheaf of papers, which stapler comprises a stapling unit (3) and a base part (2) which, by means of a connecting device (4), are connected in such manner that they can be moved toward and away from each other in a reciprocating stapling movement (P), wherein the stapling unit contains staples (8) and a driver (7) and the base part comprises a lower part (9) and an upper part (25) provided with a contact surface (26) provided with a staple opening (27) against which the workpiece to be stapled is placed during the stapling, wherein the upper part is connected to the lower part in such manner that it can be moved toward and away from the lower part during the stapling movement, wherein a latching arrangement (15, 28) is provided between the lower part and the upper part to prevent the upper part from being moved toward the lower part and wherein an anvil device (22) is arranged on the base part, wherein stapling is performed by moving the stapling unit and base part toward each other into contact with the workpiece, whereupon the driver drives a staple into the workpiece to a position in which the staple crown (34) is in contact with the workpiece and the staple legs (32,33) extend through the staple opening, whereupon a releasing device (30,3) arranged in the stapler releases the latching arrangement, whereupon the upper part and stapling unit are moved toward the lower part, whereby the staple legs are bent by the anvil device into contact with the underside of the workpiece, the anvil device (22) being attached to the to base part by means of an elastic element (19) in the area between the lower part (9) and the upper part (25), and being so arranged that it is moved toward the staple opening (27) by the elastic element to block the said opening when the stapler is in an initial position (FIG. 1).
