When the slide rod 2 slides downward, the slide rod 2 will push the slide rod 1 to slide downward. The upper end of the slide rod 2 is connected to a connecting rod, and a return spring is connected between the slide rod 1 and the crushing column. The bottom end of the connecting rod is connected to the end of the limit rod.

Control the servo motor to reverse the large gear so that the surface of the fixed bar is flush with the surface of the bottom column, reducing raw material residue and facilitating cleaning.

[0015] 3. After the bottom column contacts the stop block, the bottom column stops moving, and the limit rod continues to drive the connecting rod, slide rod 2, slide rod 1, circular plate and protrusion to move to the lower left. The protrusion squeezes the connecting column through the inclined surface, causing the push plate to move downward, and the limit rod, connecting rod, slide rod 2, slide rod 1, circular plate and protrusion continue to move. The circular plate contacts the push plate and stops moving downward. The limit rod, connecting rod, slide rod 2 and protrusion continue to move, and the push plate that continues to move downward scrapes off a small amount of bone material on the surface of the bottom column and the surface of the circular plate, reducing subsequent cleaning work.
