When the product is mixed, the push plate 63 is pushed outward to drive the insertion rod 67 to slide outward. At this time, the insertion rod 67 squeezes the spring 64. When the insertion rod 67 slides to the outermost side, the fixed ring 62 is pulled upward to drive the insertion rod 67 to disengage from the position of the slot 65, and the fixed limit of the fixed ring 62 is released. The filter screen 61 can be removed for cleaning and replacement, which is convenient for filtering the raw materials next time.
