Secondly, the connecting plate 8 is connected to the connecting frame 5 through the movable rod 7, and the two connecting plates 8 are connected to the two magnets 10. The two magnets 10 are attracted to the nut 3, and the attraction provided by the magnet 10 is more uniform and lasting, thereby improving the anti-slip reliability.

[0025] Embodiment 2, as Figure 2-Figure 4As shown, the outer walls of the two connecting plates 8 are each provided with a hole 2 11, the inner walls of the two holes 2 11 are each movably inserted with a movable rod 2 12, the outer walls of the two movable rods 2 12 are each fixedly sleeved with a connecting plate 2 13, the tops of the two connecting plates 2 13 are each provided with a threaded hole 2 14, the top of the stud bolt body 1 is provided with two threaded holes 3 15, the inner walls of the two threaded holes 3 15 are both threadedly connected with a screw 16, the outer walls of the two connecting plates 8 are each fixedly installed with a group of connecting plates 3 17, the outer walls of the two groups of connecting plates 3 17 are each provided with a fixing plate 18, the outer walls of the two fixing plates 18 are each provided with a threaded hole 4 19, the inner walls of the two threaded holes 4 19 are both threadedly connected with a screw 20, the opposite sides of the two groups of connecting plates 3 17 are each fixedly installed with a spring 21, and the inner walls of the two springs 21 are each fixedly installed with a damper 22.

[0026] The effect achieved by the entire embodiment 2 is that, first, the connecting plate 2 13 is connected to the connecting plate 1 8 through the movable rod 2 12, and the connecting plate 2 13 can be rotated through the movable rod 2 12, and secondly, the threaded hole 2 14 is aligned with the threaded hole 3 15, and the screw 16 is used to be rotated into the threaded hole 2 14 and the threaded hole 3 15 at the same time, so that the two connecting plates 1 8 can clamp and fix the nut 3, and prevent the nut 3 from slipping to a certain extent, and at the same time, the threaded hole 4 19 is aligned with the threaded hole 1 9, and then the screw 20 is passed through the threaded hole 4 19 and the threaded hole 1 9 at the same time to connect the connecting plate 3 17 with the connecting plate 1 8, and secondly, the two springs 21 can play a role of buffering and shock absorption, reduce the direct impact between the bolt and the nut 3, thereby protecting the connecting parts from damage to prevent the nut 3 from slipping.

[0027] Among them, the damper 22 is a prior art, and its components and operating principles are public technologies, which will not be explained in detail here.

[0028] Working principle: first, when the device is in normal use, a gasket 2 is first put on the outer wall of the stud bolt body 1, and then the two nuts 3 are rotated on the outer wall of the stud bolt body 1. The gasket 2 can be selected with a gasket 2 with teeth or corrugations, which can increase the friction between the contact surface, thereby improving the anti-loosening performance of the stud bolt body 1 and reducing the loosening of the nut 3 caused by vibration and other reasons. Secondly, two connecting blocks 4 are fixedly installed on the outer wall of the stud bolt body 1. The two connecting blocks 4 are fixedly connected to the two connecting frames 5, and the connecting plate 8 is connected to the connecting frame 5 through a movable rod 7. The connecting plate 8 can be rotated through the movable rod 7. At the same time, magnets 10 are arranged on the opposite sides of the two connecting plates 8. The two magnets 10 can attract the nuts 3, which can increase the friction between the nuts 3 and the stud bolt body 1 and improve the stability and reliability of the connection. The sliding of the nuts 3 will cause the stud bolt body 1 to slip, and the setting of the magnets 10 can reduce this risk to a certain extent and extend the stud bolt body 1. The service life of the body 1 is extended. Secondly, the outer wall of the two connecting plates 18 is provided with a hole 211. The two connecting plates 213 are connected to the connecting plate 18 through the movable rod 212, and the connecting plate 213 is rotated by the movable rod 212, and the connecting plate 213 is tightly attached to the top of the stud bolt body 1, so that the threaded hole 214 is aligned with the threaded hole 315, and then the two screws 16 are simultaneously rotated into the threaded hole 214 and the threaded hole 315 to strengthen the fixation of the nut 3, and then the fixing plate 18 and the connecting plate are fixed. 1 and 8 are attached to each other, so that the threaded hole four 19 is aligned with the threaded hole one 9, and then the screw two 20 is simultaneously rotated into the threaded hole four 19 and the threaded hole one 9, so that the two groups of connecting plates three 17 are fixed to the connecting plate one 8. At the same time, springs 21 are fixedly installed on the opposite sides of the two groups of connecting plates three 17. The elasticity of the spring 21 can slow down the vibration of the stud bolt body 1, thereby reducing the loosening and vibration of the nut 3. The spring 21 can reduce the fatigue damage of the stud bolt body 1 and extend the service life of the stud bolt body 1.
