Technical Field

[0001] The present application relates to the technical field of drywall screws, and in particular to a rotary drywall screw with an adjustable nail rod radius. Background Art

[0002] Drywall screws are a type of fastener specifically used to fix various decorative materials (such as gypsum boards, light steel keels, wooden trims, etc.). They are usually made of fiber, metal, plastic and other materials. The surface is covered with sharp serrations and can easily penetrate gypsum boards, wooden boards and other materials.

[0003] Existing drywall screws include a nail head and a nail body. The nail body is provided with a thread. The nail head is fixedly connected to one end of the nail body. When using drywall screws, you first need to determine the required installation position, and then use a tape measure or other measuring tool to measure the position and length to determine the number and installation position of the drywall screws; then press the end of the nail body away from the nail head to the position to be fixed, and rotate the nail head clockwise until the nail body completely passes through the gypsum board or other decorative materials to complete the fixation of the drywall screw.

[0004] With regard to the above-mentioned related technologies, when the decorative materials are hit by external objects, the threads and the decorative materials are often not in close contact, causing the decorative materials to shake. Since the radius of the nail body is not easy to adjust, this drywall screw is no longer applicable, and it is necessary to replace it with a larger drywall screw to fix the decorative materials, which is time-consuming and labor-intensive, and thus there is a defect of low applicability of the drywall screw. Summary of the invention

[0005] In order to improve the applicability of drywall screws, the present application provides a rotary drywall screw with adjustable nail rod radius.

[0008] By adopting the above technical scheme, after the drywall screw fixes the decorative material, the thread of the arc plate is in close contact with the decorative material. After the drywall screw becomes loose, the drywall screw is first removed, and when the drill bit does not rotate, the first push sleeve is pushed in the direction away from the nail head by the auxiliary component, the inclined surface of the first push sleeve abuts against the inclined surface of the arc plate, and pushes the end of the arc plate close to the nail head to move in the direction away from the nail rod, and at the same time, the auxiliary component drives the first push sleeve to rotate, and the first push sleeve drives the arc plate to rotate through the connecting component, and the arc plate drives the second push sleeve to rotate through the connecting component. Under the guidance of the thread of the nail rod, the second push sleeve moves in the direction of the first push sleeve, and the second push sleeve pushes the end of the arc plate close to the nail tail to move in the direction away from the nail rod. When the arc plate moves to the set position, the drywall screw is fixed to the decorative material from the hole originally drilled in the decorative material, and at the same time, the thread of the arc plate abuts against the decorative material, and there is no need to replace a larger drywall screw, thereby improving the applicability of the drywall screw.

During the rotation of the connecting plate, the connecting plate drives the first push sleeve to rotate, and under the guidance of the connecting component and the arc plate, the first push sleeve makes the second push sleeve move in the direction away from the nail tail, so that the auxiliary component realizes the function of driving the first push sleeve and the second push sleeve to move. At the same time, during the rotation of the annular sleeve, the annular sleeve drives the baffle plate to move toward the nail head direction. After the arc plate is adjusted, the cross groove of the baffle plate overlaps with the cross groove of the nail head. When the nail head is rotated with a cross drill bit, the drill bit simultaneously drives the baffle plate to rotate, and the baffle plate drives the annular sleeve to rotate, so that the auxiliary component can rotate synchronously with the drill bit to complete the fixation of the drywall nail to the decorative material.

[0011] Optionally, a fixing rod is fixedly provided on one side of the connecting plate facing the first pushing sleeve, and one end of the fixing rod away from the connecting plate is fixedly connected to the first pushing sleeve.

[0012] By adopting the above technical solution and setting the fixing rod, the fixed connection between the connecting plate and the first pushing sleeve is achieved.

[0013] Optionally, the connecting assembly includes a first connecting rod and a second connecting rod, one end of the first connecting rod is hinged to the side of the first push sleeve away from the nail head, one end of the first connecting rod is hinged to the arc plate away from the first push sleeve, one end of the second connecting rod is hinged to the side of the second push sleeve away from the nail tail, and one end of the second connecting rod is hinged to the arc plate.

[0014] By adopting the above technical solution, in the process of the first push sleeve moving toward the second push sleeve, the first push sleeve pushes the first connecting rod to move, and the first connecting rod pushes the arc plate to move in the direction away from the nail rod. In the process of the second push sleeve moving toward the first push sleeve, the second push sleeve pushes the second connecting rod to move, and the second push rod pushes the arc plate to move in the direction away from the nail rod. The first connecting rod and the second connecting rod are set to realize the connection between the first push sleeve and the second push sleeve and the arc plate, and the first connecting rod and the second connecting rod play a supporting role.

[0015] Optionally, an elastic pad is fixedly provided on the side of the baffle facing the nail head.

[0016] By adopting the above technical solution, the elastic pad is compressed when the baffle moves toward the nail head. The setting of the elastic pad makes it difficult for debris to enter the gap between the nail head and the annular sleeve, thereby facilitating the rotation of the annular sleeve relative to the nail head.

[0017] Optionally, an anti-slip groove is provided on a side of the annular sleeve facing away from the nail head.

[0018] By adopting the above technical solution, during the process of rotating the annular sleeve, the anti-slip groove increases the friction between the tool and the annular sleeve, thereby facilitating the rotation of the annular sleeve.

[0019] Optionally, the nail head is provided with a square groove in the middle of the cross groove.

[0020] By adopting the above technical solution, when the annular sleeve is rotated relative to the nail head, the nail head can be fixed by means of a tool that reaches into the square groove, so that the nail head is not easy to rotate during the rotation of the annular sleeve.
