The front end length of the crushing ridge 613 is smaller than the rear end length. The inner wall crushing structure is formed by the alternating arcuate concave surfaces 612 and the crushing ridges 613. When the ice cubes enter the interior of the cylinder 61, the ice cubes are quickly crushed and re-shaped and extruded through the crushing structure of the inner wall of the cylinder 61 and the rotation of the variable pitch double-thread screw 62, so that the extruded ice is more compact, thereby achieving the effect of improving the crushing efficiency of the ice making extrusion device.
