[0035] The surface of the spiral staircase 12 is set as a slope, and the slope is high near the inner wall of the storage barrel and low near the center of the storage barrel. By setting the slope, the screws to be installed that are stacked together due to friction during transportation can roll down the slope of the spiral staircase 12 back into the storage barrel to achieve the first sorting.

[0036] The conveying part 20 includes a conveying guide groove 21. The conveying part 20 is connected to the automatic sorting part 10, and a long strip conveying hole 29 for receiving the sorted screws to be installed is provided in the conveying guide groove 21, and the conveying part 20 conveys the received screws to be installed to the screw installation station.

[0037] The feed port 13 is butted against the end of the conveying guide groove 21, and a gathering channel 14 with the width of one or two screws to be installed is provided at the butt joint of the spiral step 12 and the feed port 13. The gathering channel 14 is actually a further extension of the output end of the spiral step 12, and is integrally formed with the spiral step 12 during casting, and the gathering channel 14 is butted against the long strip conveying hole 29 of the conveying guide groove 21.
