The reciprocating screw 27 drives the reciprocating block 28 to reciprocate during the rotation process. The reciprocating block 28 drives the push block 25 to reciprocate through the connecting plate 29 during the reciprocating movement. The push block 25 drives the extrusion plate 22 to reciprocate through the push rod 23 during the reciprocating movement. The extrusion plate 22 squeezes the sponge 21 during the reciprocating movement.
