An anti-burst retaining ring is also included; the anti-burst retaining ring includes an inclined sheath closely attached to the side surface of the rotating head. An anti-burst ring piece extending radially is provided on the inclined sheath. A plurality of cut holes extending radially are circumferentially arranged on the anti-burst ring piece. One end of each cut hole far from the axis of the anti-burst ring piece communicates with the outside. An anti-burst pressing piece integrated with the anti-burst ring piece is formed between two adjacent cut holes. Nails are arranged at the bottom of the anti-burst pressing piece.
[0005] The utility model is further arranged as follows: Anti-slip protrusions are arranged on the top of the anti-burst pressing piece.
[0006] The utility model is further arranged as follows: The included angle between two adjacent cut holes is equal.
[0007] The utility model is further arranged as follows: The anti-burst pressing piece can be shaped after being bent.
[0008] In summary, the utility model has the following beneficial effects: The anti-burst drywall screw according to the utility model is screwed in together with the anti-burst retaining ring. After that, through hammering, the upturned anti-burst pressing piece is hammered flat, and the nails on it are driven into the installation surface, preventing local cracking at the connection, ensuring reliable connection, having a complete overall function and strong practicability.

[0013] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the following describes the preferred implementation scheme of the present utility model in combination with specific embodiments. However, it should be understood that these descriptions are only to further illustrate the features and advantages of the present utility model, rather than a limitation on the patent requirements of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present utility model.
[0014] The present utility model will be further described below in conjunction with the accompanying drawings and preferred embodiments.
[0015] Embodiment 1
[0016] Refer to Figure 1 、 Figure 2 and Figure 4 As shown, a drywall screw for preventing expansion and cracking involved in this embodiment includes a drywall screw body 100. One end of the drywall screw body 100 has a rotating head 101 in the shape of an inverted frustum of a cone. A rotating groove (not shown) is provided in the center of the rotating head 101. It also includes an anti - expansion - cracking retaining ring 200. The anti - expansion - cracking retaining ring 200 includes an inclined sheath 201 closely attached to the side surface of the rotating head 101. An anti - expansion - cracking ring piece 202 extending radially is provided on the inclined sheath 201. A number of cut holes 203 extending radially are circumferentially arranged on the anti - expansion - cracking ring piece 202. One end of the cut hole 203 far from the axis of the anti - expansion - cracking ring piece 202 communicates with the outside. An anti - expansion - cracking pressing piece 204 integrated with the anti - expansion - cracking ring piece 202 is formed between two adjacent cut holes 203. Nails 205 are arranged at the bottom of the anti - expansion - cracking pressing piece 204.
[0017] Furthermore, the included angle between two adjacent cut holes 203 is equal.
[0018] Furthermore, the anti - expansion - cracking pressing piece 204 can be shaped after being bent.
[0019] In this implementation scheme, first, the anti - expansion - cracking retaining ring 200 is sleeved on the drywall screw body 100 until the inclined sheath 201 closely adheres to the side surface of the rotating head 101. Then, the drywall screw body 100 with the anti - expansion - cracking retaining ring 200 is screwed onto the wood or gypsum surface. Since the nails 205 at the bottom of the anti - expansion - cracking pressing piece 204 protrude from the end face, the completed drywall screw body 100 will cause the anti - expansion - cracking pressing piece 204 to tilt. Finally, a hammer is taken to strike the anti - expansion - cracking pressing piece 204 until the nails 205 at its bottom are nailed into the wood or gypsum surface to locally strengthen the connection and prevent cracking.
[0020] Example 2
[0021] Refer to Figures 1 to 4 As shown, a drywall screw for preventing expansion and cracking involved in this embodiment is further configured, on the basis of Embodiment 1, such that anti-slip protrusions 206 are arranged on the top of the anti-expansion and cracking pressing piece 204.
[0022] In this embodiment, by arranging anti-slip protrusions 206 on the top of the anti-expansion and cracking pressing piece 204, the anti-slip effect during the hammering by the hammer is achieved.
[0023] For the drywall screw for preventing expansion and cracking involved in the present utility model, the drywall screw and the anti-expansion and cracking retaining ring are screwed together, and then after hammering, the warped anti-expansion and cracking pressing piece is hammered flat until the screw is driven into the installation surface, preventing local cracking at the connection, with reliable connection, perfect overall function, and strong practicability.
