Finally, when the reciprocating screw 6 rotates, it drives the reciprocating wire sleeve 91 threadedly connected to the circumferential surface to move back and forth, thereby driving the limiting rod 97 fixed on the circumferential surface of the reciprocating wire sleeve 91 to move up and down, and at the same time drives the sliding sleeve 96 sliding on the circumferential surface of the sliding rod 95 to move up and down. When the sliding sleeve 96 moves up and down, the hollow plate 94 fixed on the circumferential surface of the connecting rod 93 is subjected to force, driving the connecting rod 93 rotating on the inner wall of the fixed block 92 to rotate, and driving the hollow plate 94 to make an arc reciprocating motion to stir the materials.
