Specifically, two guide guard plates 5 are provided above the annular support platform 2, the guide guard plates 5 play a guiding role so that the iron nails move along a certain path, the guide guard plates 5 are connected to the vibrating feeding tray 1 through an adjustable lifting connection assembly, the guide guard plates 5 are arc-shaped, and a gap is left between the guide guard plates 5 and the vibrating feeding tray 1 for the iron nail heads to pass through, one of the guide guard plates 5 is located between the discharge port of the vibrating feeding tray 1 and the first drop-out port Between the material openings 3, another guide guard plate is located between the first blanking opening 3 and the second blanking opening. After the mixed long and short iron nails are placed inside the vibrating loading tray 1, they can be arranged one by one and discharged from the discharge opening of the vibrating loading tray 1. Their heads will enter the gap between the guide guard plate 5 and the outer wall of the vibrating loading tray 1, while their rod bodies will face radially outward. The annular support platform 2 is provided with a support portion at the first blanking opening 3, and a support plate 6 is installed above the support portion. As shown in the figure, a small gap is left between the two guide guard plates 5 for the iron nail heads to pass through.
