[0018] The utility model makes further detailed explanation in combination with the drawing and specific implementation. The embodiment of the utility model is given for example and description, and is not exhaustive or limit the utility model to the disclosed form. Many modifications and changes are obvious to those skilled in the art. The embodiment is selected and described to better illustrate the principle and practical application of the utility model, and make those skilled in the art understand the utility model to design various embodiments with various modifications suitable for specific use.

[0019] Please refer to Figs. 1-5In this embodiment, a new type of extruder screw is provided, which comprises an outer cylinder 1 and a rod body 2. An adjusting motor 11 is installed on the left side end face of the outer cylinder 1. The output end of the adjusting motor 11 is provided with the rod body 2. The left side part of the rod body 2 is in a threaded structure. A screw outer ring 12 is rotatably installed on the outer side wall of the rod body 2 through threads. A cover plate 13 is installed on the right side end face of the screw outer ring 12 through a first clamp head. A plurality of plugs 15 are installed on the left side end face of the cover plate 13 along the circumferential direction thereof. The plugs 15 are installed on the right side end face of the rod body 2 through plug-in connection. An inlet is formed on the upper end of the outer side wall of the outer cylinder 1. An end cover 14 is rotatably installed on the right side end face of the outer cylinder 1 through threads. A discharge port is installed on the right side end face of the end cover 14. During operation, the material is fed into the outer cylinder 1 through the inlet. The adjusting motor 11 is started to drive the rod body 2 to rotate, so that the material is extruded through the discharge port. The contact between the screw outer ring 12 and the material is prone to wear. The threaded connection facilitates the disassembly and replacement of the screw outer ring 12, saves the replacement cost, avoids the relative rotation between the screw outer ring 12 and the rod body 2 through the plug-in structure of the plug 15, improves the stability of the device installation, and the end cover 14 is removed by rotating, then the cover plate 13 is taken out, and then the screw outer ring 12 is removed by rotating to replace it.
