By pulling the control rod outward, the movable blocks on both sides squeeze the No. 2 spring respectively, and the tooth block is separated from the arc-shaped rack. Then the control rod is turned to push the fixed sleeve and the movable disk to rotate, and the movable openings in the movable disk push the four groups of round blocks and the slider together respectively, and the four groups of spliced ​​pipe pieces are spliced ​​into a pipe body, which just corresponds to one end of the conveying pipe. After the extension of the first auger blade and the second auger blade is adapted, the pipe body of the conveying pipe is extended. The splicing of the four groups of round blocks is the same as the width of the conveying pipe, and they will be wrapped around the outside of the extended second auger blade, so that after the overall lengthening, the first auger blade and the second auger blade can transport the incoming raw materials well. The appropriately longer conveying distance meets the needs of different production lines. For production environments with limited space, the lengthened conveying pipe can reduce the floor space and improve space utilization without adding additional equipment.
