The transmission rod (30, 32) comprises a central portion (34) and two lateral portions (36, 38) positioned at opposite sides relative to the central portion (34) and forming two channel-shaped longitudinal guides (58, 61), the central portion (34) having a longitudinal groove (48) positioned between the longitudinal guides (58, 61), the longitudinal groove (48) of the central portion (44) being closed by a base (44). The transmission member (24, 25, 26, 27, 28) has a connecting portion (72) including two longitudinal ribs (78, 80) with ends shaped in such a way as to establish a telescopic coupling with the longitudinal guides (58, 61) of the transmission rod (30, 32) and a central portion positioned between said ribs (78, 80) and provided with a threaded hole (104) in which is inserted a screw (106) having a tip (110) that is able to cut a hole in the base (44) of the transmission rod (30, 32) at said longitudinal groove (48).</p> |
