摘要： A stapler comprises a stapler head (12) which accommodates a strip of wire staple blanks and is pivotable between a starting position and a working position, in which it is applied against a sheaf of papers (14). A staple shaper (20) shapes the blanks into substantially U-shaped staples, and a staple driver (21) releases the thus-formed staples from the strip and drives them one by one into the sheaf of papers (14). A pivotable operating means (15) reciprocates the staple shaper (20) and the staple driver (21). A drive means (22-26) is adapted to pivot the operating means (15) in such a manner that it causes the staple driver (21) to drive a staple into the sheaf of papers (14) in a driving stroke and causes the staple shaper (20) to shape the following staple in a shaping stroke, as well as adapted to pivot the stapler head (12) to its working position before the staple driver (21) performs the driving stroke and retain it there during the driving stroke of the staple driver. The drive means (22-26) synchronises the pivotal movements of the stapler head (12) and the operating means (15) in such a manner that the staple driver (21) performs a prolonged stroke in the driving direction and the staple shaper (20) performs the last phase of the shaping stroke when the stapler head (12) has left its working position in order to be pivoted back to its starting position.

摘要： A stapler for driving staples into a sheaf of papers comprises a base (11) and a stapler head (12) pivotably connected to the base via a first pin (13) and pivotable between a starting position and a working position in which it is applied against a sheaf of papers placed between the base and the stapler head. A reciprocating drive element (21), adapted to drive a staple into the sheaf of papers during a driving stroke, is arranged in the stapler head. A drive mechanism (15), adapted to reciprocate the drive element (21), is pivotably connected to the stapler head (12) via a second pin (16) parallel to the first pin (13). A drive means (22-26) is arranged in the base (11) for pivoting the stapler head (12) and the drive mechanism (15). A locking mechanism (36-41) is arranged in the stapler head (12) for releasably locking the latter in the working position while a staple is being driven into the sheaf of papers.
