The limiting plate extends obliquely in the direction away from the nail rod, and the limiting plate can be shaped by bending. A spike is provided on the end face of the limiting plate facing the nail rod.
[0005] The utility model is further provided as follows: The side surface of the reinforcing rib not connected to the stop plate and the nail rod is arranged in the conical side surface of a structural frustum coaxial with the nail rod, and the tip of the spike is close to the conical side surface.
[0006] The utility model is further provided as follows: The extending direction of the spike is perpendicular to the extending direction of the limiting plate.
[0007] The utility model is further provided as follows: The side surface of the process hole has an opening communicating with the outside.
[0008] The utility model is further provided as follows: The included angles between two adjacent reinforcing ribs are equal.

[0015] The utility model will be further described below in conjunction with the drawings and preferred embodiments.
[0016] Embodiment 1
[0017] Refer to Figures 1 to 3 As shown, an anti-loosening fiberboard nail involved in this embodiment includes a nail rod 1 with threads. One end of the nail rod 1 is provided with a stop plate 2. A rotation groove 3 extending into the nail rod is provided in the center of the stop plate 2. The cross-section of the rotation groove 3 is in a "cross" shape. A plurality of reinforcing ribs 4 respectively connecting the stop plate and the nail rod are circumferentially arranged between the stop plate 2 and the nail rod 1. A process hole 5 is provided in the stop plate between two adjacent reinforcing ribs 4. A limiting plate 6 with one end connected to the hole wall and the other end extending out of the process hole is provided in the process hole 5. The limiting plate 6 extends obliquely in the direction away from the nail rod. The limiting plate 6 can be shaped by bending, and a spike 7 is provided on the end face of the limiting plate 6 facing the nail rod.
[0018] Furthermore, the included angles between two adjacent reinforcing ribs 4 are equal.
[0019] In this embodiment, first, the fiberboard nail is screwed into the wooden board, and then an external tool is used to hammer the limiting plate 6, causing it to deform. The deformation also causes the spikes 7 to pierce into the wooden board, forming a circumferential limit for the fiberboard nail.
[0020] Example 2
[0021] See Figures 1 to 3 As shown, for a fiberboard nail with anti-loosening function involved in this embodiment, on the basis of Example 1, it is further set that the side surface of the reinforcing rib 4 that is not connected to the stop plate and the nail rod is arranged within the conical side surface 8 of a structural frustum coaxial with the nail rod 1, and the tip of the spike 7 is close to the conical side surface 8.
[0022] Furthermore, the extending direction of the spike 7 is perpendicular to the extending direction of the limiting plate 6.
[0023] In this embodiment, by arranging the side surface of the reinforcing rib 4 that is not connected to the stop plate and the nail rod within the conical side surface 8 of a structural frustum coaxial with the nail rod 1 and making the tip of the spike 7 close to the conical side surface 8, when screwing the fiberboard nail, the spike 7 will not interfere with the wooden board, and when hammering the limiting plate 6, the spike 7 can be quickly pierced into the wooden board.

[0026] In this embodiment, through the setting of the opening 51, it is convenient to punch and form the limiting plate 6 at one time, simplifying the processing technology.
[0027] For the fiberboard nail with anti-loosening function involved in the present utility model, by hammering the limiting plate on the screwed fiberboard nail to cause it to deform until the spikes pierce into the connecting board material, so as to achieve the circumferential limiting effect on the fiberboard nail.
