A holding means for a blade of a handsaw comprising: two plate members facing to each other and serving as a mounting part for a spare blade, one of the plate members being provided on the surface with a receiving part for retaining a cut formed on the blade; and a tightening member arranged at the other of the plate members, the tightening member having a projection, which is fit in a mounting hole formed on the blade, and a pressing surface to contact with an outer surface of that plate member, whereby when the tightening member is turned, with the blade being inserted between the two plate members, the projection enters the mounting hole of the blade and the pressing surface presses the outer surface of that plate member, thereby allowing the blade to be tightened and fixed in a manner of being firmly sandwiched between the plate members.
La présente invention a pour objet un dispositif de montage pour lame de scie à main; celui est composé de deux plaques disposées l'une en face de l'autre servant d'organe de montage pour une lame de rechange; une des deux plaques en question comporte, à sa surface, une partie en saillie destinée à recevoir une entaille pratiquée dans la lame; l'autre plaque comporte un organe de serrage présentant une projection destinée à être logée dans un trou de montage pratiqué dans la lame, une surface de pression venant en contact avec la surface extérieure de la plaque en question. Lorsque l'organe de serrage est tourné et que la lame est insérée entre les deux plaques, la projection pénètre dans le trou de montage de la lame et la surface de pression presse la surface extérieure contre cette plaque, enserrant et fixant de ce fait l'extrémité de la lame entre les plaques de montage.
