This utility model invention belongs to the field of automatic cutting machines for extrusion blow molding machines, and particularly relates to a mechanism that improves the stability of the cutting knife holder. The machine frame is slidably connected to the auxiliary support and the cutting knife holder through matching guide rails and guide sleeves. The cylinder is connected to the upper end of the cutting knife holder through a piston rod. The upper cutting knife is mounted on the lower end of the cutting knife holder, and the lower cutting knife is mounted on the upper end of the machine frame. Two fixing brackets are symmetrically arranged on the upper end of the machine frame. A bearing assembly is provided on the auxiliary support. One end of the transmission component is fixed to the fixing bracket, and the other end of the transmission component is connected to the cutting knife holder. The transmission component is connected to the bearing assembly, and a reinforcing fixing bracket connects the top of the two bearing assemblies. The beneficial effects of this utility model invention are: the reinforcing fixing bracket on the bearing assembly improves the force structure of the cutting knife holder, maintaining the relative stability of the bearing assembly, cutting knife, and cutting knife holder during the cutting process, avoiding or reducing shaking caused by mechanical vibration and other factors, and extending the service life of the bearing assembly and the cutting knife holder.
