[0012] In order to enable those skilled in the art to better understand the technical solution of the utility model, the preferred implementation scheme of the utility model is described below in conjunction with specific embodiments, but it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0013] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See also Figure 1 As shown, a fiberboard nail involved in this embodiment includes a smooth rod portion 1, a rotating portion 2 is provided at one end of the smooth rod portion 1, and a screw thread portion 3 is provided at the other end. The side surface of the smooth rod portion 1 is provided with a row of deep saw grooves 4 arranged equidistantly along its axial direction, and the deep saw grooves 4 extend along the radial direction of the smooth rod portion 1. The side surface of the smooth rod portion 1 is also provided with a row of shallow saw grooves 5 arranged equidistantly along its axial direction, and the shallow saw grooves 5 extend along the radial direction of the smooth rod portion 1, and the shallow saw grooves 5 and the deep saw grooves 4 are spaced at an angle of 180°.

[0016] Furthermore, a reinforcement column 6 is provided in the deep saw groove 4 , close to the groove opening and connecting the two groove walls, and the reinforcement column 6 extends along the axial direction of the polished rod portion 1 .

[0017] Furthermore, a shallow saw groove 5 is provided between two adjacent deep saw grooves 4 .

[0018] In this embodiment, the fiberboard nail is first screwed so that the threaded portion 3 on it is screwed into the fiberboard, and then a hammering tool is used to side-hit the rotating portion 2, so that the light rod portion 1 extending out of the fiberboard is bent toward the shallow saw groove 5. During this period, the shallow saw groove 5 is reduced in width due to deformation, and the deep saw groove 4 is increased in width due to deformation, causing the reinforcing column 6 in the deep saw groove 4 to break, and the bending continues until the light rod portion 1 is deformed into an inverted "U"-shaped structure (the rotating portion 2 is in contact with the fiberboard), simulating a hanging ring structure for hanging use.

[0019] The reinforcement column 6 is provided to enhance the structural strength of the polished rod portion 1 at the deep saw groove 4, thereby ensuring that the polished rod portion 1 has a suitable torque when the reinforcement column 6 is not broken.

[0020] Example 2

[0021] See also Figure 1 and Figure 2As shown, the fiberboard nail involved in this embodiment is further configured on the basis of Embodiment 1, wherein the side surface of the rotating portion 2 is provided with nail teeth 7 which are also spaced at an angle of 180° with the deep saw groove 4.

[0022] In this embodiment, by providing the spike teeth 7, when the rotating portion 2 contacts the fiberboard, the spike teeth 7 can break into the fiberboard and be used for secondary connection.

[0023] Example 3

[0024] See also Figure 1 and Figure 2 As shown, the fiberboard nail involved in this embodiment is further configured on the basis of Embodiments 1 and 2, wherein a retaining ring 8 close to the thread portion 3 is provided on the bare rod portion 1 .

[0025] In this embodiment, the retaining ring 8 on the polished rod portion 1 serves to limit the screw-in depth.

[0026] The fiberboard nail involved in the utility model is first connected by using the screw thread part, and then the rotating part is hammered to bend the smooth rod part in the direction of the shallow saw groove until the rotating part touches the connecting surface to form a half-closed ring structure, which is used for hanging and is easy to rotate and hang. It has complete overall functions and strong practicality.
