ABSTRACT:
This mechanism of the invention has two telescopic assemblies (1, 2) aided by a spring (20) for maintaining a maximum extension position between the assemblies. The interior assembly (1) includes a piezoelectric element (3) which is immobilized between an anvil (4) and a limiting piece (5) over which a plexor (6) hits to generate the lighting spark. The external telescopic assembly (2) is prevented from rotation relative to the internal one (1) by an angular piece (22) having orthogonal flanks. One flank of this angular piece has a central slot forming two lugs (24), which enter respective parallel notches (23) of the internal telescopic assembly (1) when crossing its wall. The other flank contacts one of the external faces of the other telescopic assembly. The spring (20) is external and is axially distant from the piezoelectric element (3). Another spring (14), for aiding the plexor (6), is totally guided in the interior of the telescopic assembly (1) and remains, in turn, included in the circular void of the closing cap (15) of the external telescopic assembly (2). The closing cap (15) is axially displaceable with respect to the assembly (2), with the windows (17) therein having a greater length for connection of the cap, and being provided with teeth (11).
