[0002] With the development of steel technology, the application of steel can be seen everywhere, and self-tapping screws are often needed when installing and connecting steel. Self-tapping screws, also known as quick-thread screws, are quick-install fasteners made of steel with galvanized and passivated surface. When connecting, first make a threaded bottom hole for the connected part, and then screw the self-tapping screw into the threaded bottom hole of the connected part.
[0003] Existing self-tapping screws can only be used to limit the vertical angle between the self-tapping screw and the steel member when performing steel connection work, making it difficult for the self-tapping screw to achieve multi-angle thread connection work, resulting in a reduced scope of use of the self-tapping screw.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Reference Figure 1-3, an anti-deviation self-tapping screw for connecting steel materials, comprising a self-tapping screw body 1, a screw head 2 connected to the top of the self-tapping screw body 1, and a reserved groove 7 opened on the inner side of the screw head 2, a first rod 3 is placed on the inner side of the left reserved groove 7, and a connecting rod 4 is fixed on the upper front of the first rod 3, a second rod 5 is placed inside the right reserved groove 7, the outer sides of the first rod 3 and the second rod 5 are both sleeved with studs 8, and the studs 8 are threadedly connected to the inner side of the reserved groove 7. By removing the studs 8, people can disassemble the rods along the reserved groove 7. The first rod 3 and the second rod 5 are A limit plate 6 is placed at the bottom of the second rod body 5, and a placement groove 9 is opened on the inner side of the limit plate 6. A movable ball head 10 is movably connected inside the placement groove 9. The right movable ball head 10 is connected to the second rod body 5, and the left movable ball head 10 is connected to the first rod body 3. The limit plate 6 has a semicircular ring structure, and the inner diameter of the limit plate 6 is larger than the outer diameter of the self-tapping screw body 1. The limit plate 6 is tightly attached to steel parts with different inclination angles, thereby limiting the downward moving self-tapping screw body 1, making it less likely to deviate. Springs are sleeved on the outer sides of the first rod body 3 and the second rod body 5;
[0021] The second rod body 5 forms a detachable structure with the connecting rod 4 through bolts, and the connecting rod 4 is distributed vertically with the first rod body 3. After the bolts are removed, the connecting rod 4 can be connected to the slots of different heights on the second rod body 5, thereby completing the inclination angle of the limit plate 6 connected to the bottom of the rod body. The second rod body 5 forms a movable structure with the limit plate 6 through the movable ball head 10. After the first rod body 3 and the second rod body 5 have a height difference, and a rotation operation is performed between the movable ball head 10 at the bottom of the rod body and the limit plate 6, the limit plate 6 will tilt, which is convenient for the self-tapping screw to perform subsequent connection work. The middle part of the connecting rod 4 is an arc-shaped structure, and the middle part of the connecting rod 4 is set to an arc structure, which is convenient for people to twist the screw head 2 and reserve operating space for it.
[0022] Working principle: When in use, the staff first adjusts the angle of the limit plate 6 according to the angle of the steel part to be connected. During this period, people can bolt the connecting rod 4 connected to the front of the first rod body 3 to the hole grooves at different heights above the front of the second rod body 5, so that the limit plate 6 connected to the bottom of the rod body through the movable ball head 10 is tilted, and then it is pressed against the surface of the steel part. Then, the staff twists the screw head 2, and the limit plate 6 can prevent the self-tapping screw body 1 from deviating until the self-tapping screw completes the connection work.
[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
