Zusammenfassung:	The utility model relates to the technical field of mounting a plastic extruder screw, in particular to a screw mounting device. The device comprises a machine barrel containing a screw and a headstock positioned at an end head of the machine barrel, wherein a sleeve with an enclosed end is fixedly sleeved on the end head of the machine barrel through the headstock; and a lead screw is in thread fit with an opening on an enclosed end face of the sleeve, and is butted with an end head of the screw. The screw mounting device turns the helical motion of the lead screw into the uniform rectilinear translation of the screw, thereby avoiding the beating and impact on the front portion of the screw caused by the prior shock mounting method, reducing the labor intensity in mounting and increasing the mounting speed for the screw.
