Patent ID: 7021515

Claim:
A stapler comprising: a base section having a support surface on which a workpiece is placed to be stapled, the support surface having an open slot; and a stapling unit attached to the base section in a pivoting manner through a first pivot shaft and housing a magazine in which staples are stored, the stapling unit having a driver which serves to drive staples individually into the workpiece, wherein in a driving action the stapling unit is pressed into contact with the workpiece and the driver acts to drive a staple into the workpiece to a bottom position in which a crown of the staple is in contact with the workpiece and legs of the staple extend through the workpiece and the open slot in the support surface, wherein the base section is attached to a baseplate through a second pivot shaft and, in an initial position, is fixed relative to the baseplate through a locking mechanism attached to the baseplate and the base section, an area of the base section underneath the support surface houses pivoted bending arms, the stapling unit has a releasing device which releases the locking mechanism when the driver has driven the staple into the workpiece to a position in which the crown of the staple is in contact with the workpiece, whereupon the base section pivots by way of the second pivot shaft and is tilted against the baseplate causing the bending arms to pivot so that the legs of the staple are bent into position against the workpiece, and an underside of the support surface has a cutting pad in an area between the bending arms, the cutting pad interacting with the bending arms to cut off excess length of the staple legs when they are bent against the workpiece by the bending arms.
