The utility model discloses a
medium density fiberboard cutting device which comprises a bottom box body, a connecting concave plate is arranged at the top of the bottom box body, supporting leg assemblies are fixedly connected to the four corners of the bottom of the bottom box body, and a
cutting assembly is fixedly connected to the top of the connecting concave plate. According to the screw block
cutting device, the convex plate is connected with the clamping box, so that the screw block can move towards the inner side more stably, the phenomenon that the screw block inclines is avoided, the
transverse groove assembly is connected with the sliding rod, and therefore the screw block can be
cut more stably, and the cutting efficiency is improved. According to the device, a sliding rod
assembly can be driven to slide in a protruding plate more smoothly, friction between the sliding rod assembly and the protruding plate is reduced, the service life of the sliding rod assembly is prolonged, meanwhile, the sliding rod assembly is limited, a limiting frame is connected with a screw block, the screw block can move towards the inner side more stably, and the service life of the screw block is prolonged. And the phenomenon of inclination of the screw block is avoided.
