The anchor bolt provided by the utility model can selectively use a plurality of force-bearing members for connection according to the need of connection strength, and has good versatility and economy. Although this kind of anchor bolt has the effect of improving its versatility and economy, it is lacking in anti-pullout. Since this kind of anchor bolt does not have an anti-pullout structure, when strong winds occur, the anchor bolt will shake, thereby causing the fixed structure to loosen. Utility Model Content

The threaded connection design of the screw rod 6 and the rotating plate 9 has the effect of driving the slide plate 8 to slide in the bolt body 1 through the rotating plate 9 when the screw rod 6 is rotated. The surface of the rotating plate 9 is rotatably connected with a spur 10, and the spur 10 is slidably connected to the limiting groove 5. A sliding groove 11 is provided on the surface of the spur 10, and the limiting rod 7 is slidably connected to the sliding groove 11. The sliding design of the limiting rod 7 and the sliding groove 11 has the effect of limiting the spur 10 when the spur 10 moves.

[0025] Embodiment 2

[0026] See also Figure 1-5A fixing hole 12 is provided on the bottom surface of the bolt body 1, and a limiting hole 13 is provided on the bottom of the bolt body 1. An insert rod 14 is fixedly installed on the surface of the drill bit 4, and the insert rod 14 is slidably connected to the limiting hole 13. The sliding design of the insert rod 14 and the limiting hole has the effect of limiting the drill bit 4 when installing the drill bit 4. An insert strip 15 is inserted inside the drill bit 4, and the design of the insert strip 15 has the effect of facilitating the disassembly and replacement of the drill bit 4. The insert strip 15 is slidably connected to the drill bit 4, and a fixing rod 16 is fixedly installed on the surface of the insert strip 15, and the fixing rod 16 is threadedly connected to the fixing hole 12. The threaded connection design of the fixing rod 16 and the fixing hole 12 has the effect of facilitating the disassembly and assembly of the drill bit 4.

[0027] Working principle: when using the bolt body 1, first install the bolt body 1, and then rotate the rotating block 3 after the bolt body 1 is installed. The rotating block 3 will drive the screw rod 6 to rotate. When the screw rod 6 rotates, it will drive the slide plate 8 to slide inside the bolt body 1 through the rotating plate 9. When the slide plate 8 moves, it will drive the spur 10 to rotate. When the spur 10 rotates, it will slide on the surface of the limit rod 7 through the slide groove 11. After the spur 10 is unfolded, the bolt body 1 can be fixed. The rotating block 3, screw rod 6, rotating plate 9, slide plate 8, spur 10, limit rod 7, slide groove 11 and limit groove 5 make it easy to unfold the spur 10, thereby improving the pull-out resistance of the bolt body 1, thereby preventing the fixed structure from shaking in strong wind weather. When replacing the bolt, it is only necessary to rotate the inserting strip 15, which will drive the fixing rod 16 to rotate. After the fixing rod 16 is rotated out of the fixing hole 12, the inserting strip 14 can be pulled out of the limiting hole 13 through the drill bit 4, and then a new drill bit 4 is inserted into the limiting hole 13 through the inserting rod 14. After the inserting rod 14 is inserted, the inserting strip 15 is inserted into the drill bit 4, and then the inserting strip 15 is rotated, which will drive the fixing rod 16 to rotate until the fixing rod 16 is connected to the fixing hole 12 through a thread. The fixing hole 12, the limiting hole 13, the limiting rod 7, the inserting strip 15 and the fixing rod 16 have the effect of disassembling and assembling the drill bit 4 when the drill bit 4 is seriously damaged, thereby avoiding the need to replace the bolt body 1 when the drill bit 4 is damaged, thereby reducing the maintenance cost.
