PCT No. PCT/SE93/00164 Sec. 371 Date Oct. 6, 1994 Sec. 102(e) Date Oct. 6, 1994 PCT Filed Feb. 26, 1993 PCT Pub. No. WO93/19898 PCT Pub. Date Oct. 14, 1993A stapler for driving staples (5) into an object (6) has a frame (1), a magazine (2) arranged in the frame and containing staples (5), and a drive element (3) adapted to push staples (5) out of the magazine (2) and drive them into the object (6) and, to this end, be reciprocated by means of a drive mechanism. The drive mechanism consists of a drive cylinder (19) rotatably mounted in the frame (1) and having an endless groove (23) in its circumferential surface. The groove (23) extends substantially helically from a starting point to a turning point axially spaced therefrom, and thence substantially helically back to the starting point. The groove (23) accommodates a groove follower (24) connected to the drive element (3) in order, upon rotation of the drive cylinder (19), to reciprocate the drive element (3). |
