Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figure 1-2 , the technical solution provided by the present utility model: an anti-cracking screw, including a screw body 1, the screw body 1 includes a rod body 2, a sharp end 3 is integrally formed at the bottom end of the rod body 2, a screw head 4 is integrally formed at the top end of the rod body 2, a threaded section 5 is integrally formed on the outer wall of the rod body 2, and the threaded section 5 extends to the outside of the sharp end 3. A notch 6 is opened on the side wall of the sharp end 3, and the notch 6 extends downward to the rod body 2. A rotating groove 7 is opened at the top end of the screw head 4, and the notch 6 is arranged as an inclined plane;
[0020] Through the rod body 2 and the sharp end 3 in the screw body 1, an attachment foundation can be provided for the threaded section 5, and under the action of the sharp end 3 and the threaded section 5, the rod body 2 can be drilled into the wooden board. Since the top end of the rod body 2 is integrally formed with a screw head 4, and a rotation groove 7 is provided at the top end of the screw head 4, it is convenient for the user to place the screwdriver against the rotation groove 7, and then the screw head 4 can be rotated, so as to rotate the rod body 2. Since a notch 6 is provided on the side wall of the sharp end 3 and the notch 6 extends downward to the rod body 2, when the sharp end 3 drills a hole in the wooden board, the position of the notch 6 with an inclined plane will reduce the lateral extrusion of the wooden board, thereby reducing the damage of the threaded section 5 to the wooden board, and further ensuring the safety of drilling the wooden board.
[0021] Refer to Figure 1 、 Figure 2 , the length of the rod body 2 is 30 - 60 mm, which is convenient for the user to flexibly select a suitable length of the rod body 2 to drill the wooden board according to the needs.
