On the side of the support sleeve 6 away from the guide sleeve 3, there is an outlet sleeve 5 coaxial with the guide sleeve 3. In the initial state, there are two ways of feeding nails into the wheel axle inlet sleeve 4. The first is gravity feeding. By connecting a long pipe to the inlet of the wheel axle inlet sleeve 4, a plurality of wheel axles ready to enter the wheel axle inlet sleeve 4 are arranged in sequence in the long pipe, and the wheel axles slide into the wheel axle inlet sleeve 4 in sequence by gravity. The second is manual feeding, and the worker puts the wheel axles into the wheel axle inlet sleeve 4 one by one.

[0026] A further embodiment of the rotary cylinder 7 in the present utility model: A first adjustment limit screw 701 and a second adjustment limit screw 702 are respectively provided at the top of the rotary cylinder 7. The first adjustment limit screw 701 and the second adjustment limit screw 702 on the rotary cylinder 7 are used to adjust the maximum stroke of the rotation of the rotating body 9. During operation, when the rotary cylinder 7 requires the rotating body 9 to make reciprocating rotations, after working for a long time, the through hole 32 will be misaligned with the inlet sleeve 4 and the wheel axle slideway 12. By rotating the first adjustment limit screw 701 and the second adjustment limit screw 702, the misalignment between the through hole 32 and the inlet sleeve 4 and the wheel axle slideway 12 can be eliminated.

[0028] During use: The present utility model replaces the magazine-type bin feeding mechanism and the translation material distribution mechanism in the prior art by using a rotary nail feeding mechanism. By inserting the wheel axle into the wheel axle receiving cavity 30 through the wheel axle inlet sleeve 4, and rotating the rotating body 9 to connect the wheel axle receiving cavity 30 with the wheel axle slideway 12, the pressing shaft mechanism 14 can then press the wheel axle into the hole 1101 of the furniture wheel skeleton 11. The mounting plate 21 can fix the bracket sleeve 6 on the outer wall of the rotary cylinder 7. The slot 22 facilitates observing the rotation of the wheel axle receiving cavity 30 on the rotating body 9. In the initial state, there are two ways to feed the wheel axle into the wheel axle inlet sleeve 4. The first is gravity feeding. By connecting a long tube to the inlet of the wheel axle inlet sleeve 4, multiple wheel axles ready to enter the wheel axle inlet sleeve 4 are arranged in sequence in the long tube, and the wheel axles slide into the wheel axle inlet sleeve 4 in sequence by gravity. The second is manual feeding. Workers put the wheel axles into the wheel axle inlet sleeve 4 one by one. The length of the through hole 32 on the square block 31 is set to be the same as the length of the square of the wheel axle. When the wheel axle enters the through hole 32, another wheel axle will be temporarily stored in the wheel axle inlet sleeve 4. Then, by rotating the rotating body 9 to connect the through hole 32 with the guide sleeve 3 and the outlet sleeve 5, the ejector pin 2 can press the wheel axle into the hole 1101 of the furniture wheel skeleton 11. When the rotating body 9 rotates back to its original position, the next wheel axle will flow into the through hole 32 from the wheel axle inlet sleeve 4 automatically. The furniture wheel skeleton 11 is placed on one side of the outlet sleeve 5 through a fixture, and the hole 1101 on the furniture wheel skeleton 11 is in the same straight line as the outlet sleeve 5. The first adjustment limit screw 701 and the second adjustment limit screw 702 on the rotary cylinder 7 are used to adjust the maximum stroke of the rotation of the rotating body 9. During operation, when the rotary cylinder 7 needs the rotating body 9 to make reciprocating rotations, after working for a long time, the through hole 32 may be misaligned with the inlet sleeve 4 and the wheel axle slideway 12. By rotating the first adjustment limit screw 701 and the second adjustment limit screw 702, the misalignment between the through hole 32 and the inlet sleeve 4 and the wheel axle slideway 12 can be eliminated.
