The upward rotation of the bolts will contact the baffle 4. 3, then the bolt is separated from the fixing clamp 17 and falls onto the buffer plate 4 under the action of gravity. The buffer plate 4 rotates counterclockwise by a certain angle due to the inertia of the falling screw, and the elastic member 42 is compressed immediately, and the inner rod of the elastic member 42 moves downward. After losing the inertia, the inner rod of the elastic member 42 moves upward to return to its original position under the action of the resetting of the elastic member 42, and the buffer plate 4 also rotates clockwise by a certain angle to return to its original position, and the screw slides down along the buffer plate 4 into the collection box 41, thereby completing the automatic feeding, processing and collection of the screw.
