Said go up saw blade and one of them plane between the following saw blade be provided with to about saw blade carry out the round boss of axial limiting and circular distribution.
Described saw blade travelling gear down is provided with second bearing that is fixed on the cutting machine protecgulum.
Described output shaft is provided with the 4th bearing that is fixed on the cutting machine head capsule.
After adopting said structure; With following advantage of prior art and effect: the one owing to be provided with special-shaped projection and powerful magnet steel at the end face of lower flange; Through special-shaped projection following saw blade is carried out radial location, hold down saw blade, cut in the saw blade rotation cutting process under guaranteeing and steadily, axially do not go here and there through powerful magnet steel magnetic attraction; The cutting stable working is reliable, and cutting accuracy is high; The 2nd and since one of them plane between last saw blade and the following saw blade be provided with to about saw blade carry out the round boss of axial limiting and circular distribution; Can guarantee to remain between two saw blades suitable gap; Make job stability better, use more steadily reliable.
