[0002] When assembling steel structures, bolt sets are used for fastening. Existing bolt sets generally consist of bolts and nuts. After the bolt set is fastened to the steel structure, the steel structure will shake and vibrate due to external environmental factors during use, which will cause the bolts and nuts to loosen. This will make the connection structure of the steel structure unstable. Therefore, a bolt fastening device is needed.

[0003] Current steel structure bolt fastening equipment is not able to secure steel structures well during use, and is prone to loosening due to vibration. Furthermore, current steel structure bolt fastening equipment is inconvenient to operate. Summary of the Invention

The fastening assembly includes fastening plates, the inner walls of which are movably sleeved with the outer walls of the screws, and gaskets are fixedly connected to the opposite surfaces of the two fastening plates. A magnet is fixedly connected to one side of the opposite surface of each of the two gaskets, and the magnetic poles of the opposite surfaces of the two magnets are the same. The inner walls of the left and right portions of the fastening plate are rotatably connected with locking blocks, and a limiting component is attached to the side of the two locking blocks that are far apart from each other. The limiting component is installed in the inner cavity of the fastening plate.

[0005] Preferably, a second magnet is fixedly connected to the other side of the opposite surface of each of the two gaskets, and the magnetic poles of the opposite surfaces of the two second magnets are the same.

[0006] Preferably, the outer walls of the bolt head and nut on opposite sides are provided with limiting grooves, and the outer wall of the locking block engages with the inner wall of the limiting groove.

[0007] Preferably, the limiting component includes a connecting plate, the outer wall of the connecting plate being slidably connected to the inner cavity of the fastening plate, limiting posts being fixedly connected to both the left and right sides of the connecting plate, the opposite faces of the two limiting posts overlapping the opposite sides of the two locking blocks, the front and rear portions of the outer walls of the two limiting posts being respectively locked into the inner cavity of the fastening plate, a return spring being fixedly connected to the front of each of the two limiting posts, the outer walls of the two return springs being movably sleeved into the inner cavity of the fastening plate, the front of the two return springs being respectively fixedly connected to the inner cavity of the fastening plate, and a locking groove being formed on the front of the middle part of the locking block, with the limiting post being slidably connected to the locking groove.
