[0002] As the furniture industry increasingly demands higher assembly efficiency and connection stability, traditional furniture connection methods such as screws and nails often suffer from complex installation and unstable connections. Especially in modern quick-assembly furniture, self-tapping screws have become a common solution for quickly fixing furniture together to simplify the assembly process and improve connection strength. However, existing self-tapping screws have relatively simple structures and typically can only be fixed inside the furniture using a screwdriver, resulting in a limited operating method. Furthermore, screwdrivers are difficult to use with harder materials. Therefore, there is a need for a furniture connection self-tapping screw that can be fixed using multiple methods, including using a Torx wrench or a screwdriver, to adapt to different situations.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figures 1 to 4 This utility model provides an integrated self-tapping screw for furniture connections, comprising a stud 1, a screw tip 2 fixedly connected to the lower surface of the stud 1, a connecting circular plate 3 fixedly connected to the lower end of the inner annular surface of the stud 1, a fixing bracket 4 fixedly connected to the upper surface of the connecting circular plate 3, a connecting plate 5 fixedly connected to the upper surface of the fixing bracket 4, a connecting device 6 provided on the upper surface of the connecting plate 5, and an adjustment device 7 provided on the upper side of the connecting device 6. The fixing bracket is made of high-strength material and can effectively support the structure of the stud 1, making it stable.

[0022] The connecting device 6 includes a fixing block 601, a slot 602, a rotating hole 603, and a nut 604. The fixing block 601 is fixedly connected to the upper surface of the connecting plate 5. The slot 602 is fixedly disposed on the upper surface of the fixing block 601, the rotating hole 603 is fixedly disposed at the center end of the slot 602, and the nut 604 is fixedly connected to the upper surface of the fixing block 601. The nut 604 is made of a high-strength material, and the outer surface of the nut 604 is coated with a lubricating coating to facilitate connection with the plum blossom tube 707.

[0023] The adjusting device 7 includes a positioning rod 701, a rotating rod 702, a rotating column 703, a threaded rod 704, a threaded sleeve 705, a cover plate 706, a perforated tube 707, a connecting tube 708, a rotating handle 709, and an adjusting handle 710. The positioning rod 701 is movably connected to the inner annular surface of the rotating hole 603. The rotating rod 702 is fixedly connected to the upper surface of the positioning rod 701, the rotating column 703 is fixedly connected to the upper surface of the rotating rod 702, and the threaded rod 704 is fixedly connected to the upper surface of the rotating column 703. The threaded sleeve 705 is threadedly connected to the annular surface of the threaded rod 704, the cover plate 706 is fixedly connected to the outer annular surface of the threaded sleeve 705, and the perforated tube 707 is fixedly connected to the lower surface of the cover plate 706. The connecting tube 708 is fixedly connected to the upper surface of the cover plate 706, the rotating handle 709 is fixedly connected to the annular surface of the connecting tube 708, the adjusting handle 710 is fixedly connected to the upper surface of the threaded rod 704, the positioning rod 701 is made of a smooth material, and the size of the positioning rod 701 can be equal to the opening size of the rotating hole 603.

[0024] Working Principle: When using this product, especially when dealing with hard materials where screwdrivers are difficult to apply, first place the screw tip 2 on the surface of the furniture where the screw needs to be driven in. Then, use the adjusting handle 710 to rotate the threaded rod 704. The rotating threaded rod 704 can move within the threaded sleeve 705. By continuously rotating the adjusting handle 710, the threaded rod 704 moves upward, which in turn moves the rotating column 703 upward. The upward movement of the rotating column 703 moves the rotating rod 702 downward, which in turn moves the positioning rod 701 upward. The positioning rod 701, rotating rod 702, and rotating column 703 all move upward simultaneously under the influence of the threaded rod 704, retracting into the Torx tube 707. Finally, the Torx tube 707 is used to fix the screw in place. On the cap 604, rotate the rotating handle 709 to drive the plum blossom tube 707 to rotate, thereby driving the stud 1 to rotate. The rotation of the stud 1 drives the screw tip 2 into the furniture to fix the furniture. If facing some narrow positions, or if it is necessary to drive the screw completely into the device, the plum blossom tube 707 cannot be used. In this case, the above method can be used again to rotate the adjusting handle 710 in the opposite direction. This will cause the positioning rod 701, the rotating rod 702 and the rotating column 703 to move downwards under the drive of the threaded rod 704 and protrude from the plum blossom tube 707. After protruding, the positioning rod 701 can be put into the rotating hole 603, and the rotating rod 702 will also be inserted into the slot 602. Then, by rotating the adjusting device 7, the nut 604 is rotated to drive the screw in.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
