PUSH-PUSH MECHANISM FOR HAND TOOL, CRIMPING CLIPPER PROVIDED WITH SUCH A MECHANISM AND CRIMPING METHOD

摘要

The present invention proposes a step-by-step thrusting mechanism intended to be fixed in a hollow body of a tool, making it possible to obtain a thrust movement that is easy to implement. To this end, the mechanism comprises: • a rack (2) having: o a first (3) and a second toothing (4) with rearwardly inclined teeth (3a, 4a) arranged respectively on an upper edge ( 2a) and lower (2b); a front end (2c); A pivoting lever (5) comprising a hollow upper end (5a) receiving a torsion spring (6) bearing against said hollow upper end (5a) of the lever and resting against a pawl (7) for pivoting thrust in the body hollow (1), in front of the upper hollow end (5a) of the lever, and provided with a cross member (7a) engaged between the teeth (3a) of the first toothing (3); A pivoting locking pawl (8) provided with a cross member (8a) engaged between the teeth (4a) of the second toothing (4), a compression spring (9) being arranged in abutment with the locking pawl ( 8) and bearing against a stop (2d) located at a rear end (2e) of the rack (2).
