Abstract
In a sabre saw machine (10), having a device (20; 120) for chucking the saw blade (22; 122) on the lower end of its reciprocating rod (18; 118), wherein a chucking tube (34; 134), disposed so as to be axially displaceable by rotation on the reciprocating rod (18; 118), has an inward-protruding encompassing collar (42; 142) on its free lower end, the collar having a through opening (44; 144) and a radial slot (45; 145); wherein the collar (42; 142) in the chucking position is braced axially against lugs (68; 69; 168, 169) of the chucking end (23; 123) of the saw blade (22; 122) and thus puts it in contact with the lower face end of the reciprocating rod (18; 118) or keeps it pressed against a resilient centering piece (56; 156); wherein the reciprocating rod (18; 118) is guided in one upper and one lower reciprocating rod bearing (26, 27; 26', 27'), the guidance of the reciprocating rod (18) is improved in that the reciprocating rod (18; 118) is guided in the lower reciprocating rod bearing (27) by means of the chucking tube (34; 134), and the chucking tube (34; 134), in particular jointly with the chucking end (23; 123) of the saw blade (22; 122), passes through the reciprocating r…
