[0002] Screws are a common fastener that is widely used in machinery, electrical appliances and buildings. They are generally made of metal or plastic, cylindrical in shape, and have concave and convex grooves on the surface called threads.

[0003] The currently used screw nuts are only provided with an outer hexagonal protrusion for rotating the screw for installation, and the installation method is single. After the screw head is drilled in, the screw may be partially missed outside the installation object due to the thin volume of the installation object, causing danger in the later stage. Utility Model Content

[0006] Preferably, the connecting assembly comprises a circular hole opened inwardly on one side surface of the bottom of the screw body, and an internal thread is opened around the inner wall of the circular hole.

[0007] Preferably, the drilling portion includes a connecting column inserted into the circular hole, and an external thread matching the internal thread is provided around the outer side of the connecting column.

[0008] Preferably, a drill bit is provided at one end of the connecting column away from the connecting column.

[0009] Preferably, an outer convex portion is provided on the upper surface of the gasket, and an inner concave portion is provided vertically downward in the center of the upper surface of the outer convex portion.

[0010] Preferably, the outer convex portion is in an outer hexagonal shape, and the inner concave portion is in an inner hexagonal shape.

[0011] Preferably, a plurality of friction contacts are equidistantly arranged on one side of the gasket facing the screw body.

[0012] The technical effects and advantages of the utility model are as follows: the hexagonal bolt with a split structure can, when installing the screw, on the one hand, use a tightener to be sleeved on the hexagonal outer convex part, and the screw can be rotated for installation by rotating the outer convex part; on the other hand, a hexagonal stud can be inserted into the inner recessed part, and the screw can be installed as the hexagonal stud rotates to drive the screw to rotate; when the installation is completed and the screw body needs to be removed, at this time, it is only necessary to rotate the screw head, and let the rotation direction be opposite to the engaging rotation direction of the internal thread and the external thread, so that the screw body can be removed from the installed surface, leaving only the drilled hole part in the installation surface, so that the surface of the installed surface is smooth and will not be exposed, thereby improving practicality and safety.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] To facilitate the installation of the screws, refer to Figure 1 , Figure 2 and Figure 3As shown, it includes a screw 1, including a screw body 1, a screw head 2, a drilling part and a connecting assembly. The screw head 2 is arranged at the top of the screw body 1, and a gasket 3 is arranged between the screw head 2 and the screw body 1. The drilling part is arranged at the end of the screw body 1 away from the screw head 2. The connecting assembly is used to disassemble and assemble the drilling part on the screw body 1. The screw head 2 is cylindrical, and a hollow groove is arranged at the center of the screw. The hollow groove can reduce the weight of the screw while maintaining the installation and fixing function of the screw, saving raw materials, and facilitating operation. The diameter of the hollow groove does not exceed half of the diameter of the screw body 18. When installing the screw, on the one hand, a tightener can be used to be sleeved on the hexagonal outer protrusion 7, and the screw can be rotated for installation by rotating the outer protrusion 7. On the other hand, a hexagonal stud can be inserted into the inner recess 8. As the hexagonal stud rotates, the screw can also be installed. When the installation is completed, if the screw body 1 needs to be removed, at this time, only the screw head 2 needs to be rotated, and the direction of its rotation is opposite to the engaged rotation direction of the internal thread and the external thread, so that the screw body 1 can be removed from the installed surface, leaving only the drilled part in the installation surface, so that the surface of the installed surface is smooth and will not be exposed.

[0020] To facilitate the removal of the screw body 1, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, preferably, the connection assembly includes a circular hole 4 opened inwardly on one side surface of the bottom of the screw body 1, and an internal thread is opened around the inner wall of the circular hole 4. The drilling part includes a connecting column 5 inserted into the circular hole 4, and an external thread matching the internal thread is opened around the outer side of the connecting column 5. The connecting column 5 is installed in the circular hole 4 through the matching of the internal thread and the external thread, and the rotation direction of the internal thread and the external thread is consistent with the rotation direction of the screw body 1, so that the drilling part is drilled into the installation surface. The connecting column 5 is provided with a drill bit 6 at one end away from the connecting column 5, and the drill bit 6 is rotated to complete the overall installation and embedding. An outer protrusion 7 is provided on the upper surface of the gasket 3, and an inner recess 8 is provided vertically downward in the center of the upper surface of the outer protrusion 7. The outer protrusion 7 is in an outer hexagonal shape, and the inner recess 8 is in an inner hexagonal shape. The specific shape of the inner recess 8 is not limited to the hexagonal shape, but is preferably an inner hexagonal shape. The gasket 3 is provided with a plurality of friction contacts 9 at equal intervals on the side facing the screw body 1. The friction contact 9 increases the friction with the mounting surface, thereby improving the stability of the screw body 1 during installation.

[0021] When in use, first align the screw head 2 with the installation position, then sleeve the tightener on the outside of the outer protrusion 7, and clamp it with the outside of the outer protrusion 7 and the upper surface of the pad, rotate the tightener to make the screw head 2 drill into the installation position, and as the screw body 1 rotates, use the hexagonal stud to be inserted into the inner recess 8. As the hexagonal stud rotates, the screw body 1 is driven to rotate, and the connecting column 5 is driven to rotate, so that the drill bit 6 is rotated to make the whole drill into the installed body. When disassembling, the rotation direction of the screw head 2 needs to be reversed to the mating rotation direction of the internal thread and the external thread to separate the screw body 1 from the connecting column 5.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
