When a group of slide bars 24 rotate to correspond to the position of a group of slide grooves 22, the connecting rod 27, the connecting rod 25 and the telescopic rod 23 and the slide bars 24 thereon descend, which can drive the U-shaped hinge 15 to descend, thereby driving the first base plate 7 and the second base plate 8 to rotate. When the circular plate 26 descends to the top of the limit plate 20 and abuts against it, the bolt discharge port and the nut discharge port are in a fully open state. When a bolt receiving box and a nut receiving box are placed at the bottom of the bolt temporary storage box 5 and the nut temporary storage box 6, the bolts and nuts can directly fall into the bolt receiving box and the nut receiving box. When the bolt collecting box and the nut collecting box are full and need to be replaced, the operating disk 28 is pulled upward to drive the U-shaped hinge 15 to move upward, and the first bottom plate 7 and the second bottom plate 8 can be driven to rotate upward synchronously. When the slide bar 24 is completely moved up to the upper end of the limit plate 20, the second bottom plate 8 and the first bottom plate 7 are attached to the bottom of the bolt temporary storage box 5 and the nut temporary storage box 6, so that the bolt discharge port and the nut discharge port can be closed, and then the operating disk 28 is rotated to make the slide bar 24 misaligned with the slide groove 22, and the slide bar 24 is against the top surface of the limit plate 20, so that the closed state of the bolt discharge port and the nut discharge port is maintained. At this time, the bolt temporary storage box 5 and the nut temporary storage box 6 can be used to temporarily store bolts and nuts.
