[0032] The working principle of the utility model is as follows: when the extruder head 4 needs to be replaced, the fixing bolt 20 is first disassembled by an external tool, the rotating circle 7 is rotated, and the plugging ring 10 moves in the moving groove 9 as the rotating circle 7 rotates, and the plugging ring 10 drives the guide block 11 to slide in the guide groove 8, disengage from the groove, and take out the extruder head 4, and then insert the new extruder head 4 into one side of the extrusion pipe 2, so that the fixing ring 5 and the positioning ring 6 are close, and the rotating circle 7 is rotated. As the rotating circle 7 rotates, the plugging ring 10 drives the guide block 11 to slide in the guide groove 8, disengage from the groove, and take out the extruder head 4, and then insert the new extruder head 4 into one side of the extrusion pipe 2, so that the fixing ring 5 and the positioning ring 6 are close, and the rotating circle 7 is rotated. The block 11 slides in the guide groove 8 and is inserted into the groove, and then the fixing bolt 20 is fixed with an external tool, so that the extrusion pipe 2 and the extrusion head 4 can be connected more tightly. When the filter 12 needs to be cleaned, the positioning bolt 18 is first disassembled by an external tool, and the fixing plate 3 is taken outward to drive the plug-in block 19 out of the clamping groove 17.
