[0022] In detail, an insert block 27 is fixedly installed on the bottom end of the limit plate 28, and the number of the insert blocks 27 is thirty. The insert block 27 is provided to facilitate insertion into the slot 21. A pull rod 25 is fixedly installed on the top end of the limit plate 28. The cross-sectional shape of the pull rod 25 is T-shaped. The pull rod 25 is provided to facilitate pulling the limit plate 28 to slide along the inner wall of the slide groove 26. The top end of the pull rod 25 passes through the top end of the bolt body 1. The number of the pull rods 25 is six. A through hole 210 is opened on the pull rod 25. The through hole 210 is provided to facilitate the insertion of the screw rod 24. The shape of the through hole 210 is a cylindrical hole. A spring 211 is fixedly installed on the top end of the limit plate 28. One end of the spring 211 is fixedly connected to the inner wall of the slide groove 26. The setting of the spring 211 facilitates the application of force to the limit plate 28.

[0023] In more detail, a threaded hole 29 is provided on the bolt body 1. The threaded hole 29 is provided to facilitate the installation of the screw rod 24. The screw rod 24 is connected to the inner thread of the threaded hole 29. The screw rod 24 is provided to facilitate insertion into the through hole 210, thereby achieving the purpose of limiting the pull rod 25. The gasket 23 is provided with slots 21 and mounting holes 22. The number of slots 21 is thirty. The slots 21 are provided to facilitate the insertion of the plug block 27. The number of mounting holes 22 is four. The mounting holes 22 are provided to facilitate the fixing of the gasket 23 to the bolt mounting surface with rivets. When the bolt is installed, the gasket 23 is first placed on the mounting surface, and fixed by passing the rivet through the mounting hole 22, and then the screw rod 2 is removed from the threaded hole 29. 4, then pull the pull rod 25, the pull rod 25 drives the limit plate 28 to slide along the inner wall of the slide groove 26, when the limit plate 28 slides, it will drive the plug block 27 to enter the slide groove 26, until the through hole 210 on the pull rod 25 moves out of the bolt body 1, and then insert the screw rod 24 into the through hole 210 to prevent the limit plate 28 from returning to its original position, and then pass the bolt body 1 through the center of the gasket 23 and threadedly connect it to the mounting surface until the nut on the bolt body 1 contacts and squeezes the buffer wear-resistant pad 3, at this time, pull the screw rod 24 out of the through hole 210, and the limit plate 28 will drive the plug block 27 to contact the gasket 23 under the action of the spring 211, and then fine-tune the bolt body 1 so that the plug block 27 is inserted into the slot 21, thereby realizing the limit fixation of the bolt.

[0024] Finally, the buffer wear pad 3 is made of rubber, which has excellent elasticity and energy absorption capacity, and can effectively absorb and disperse impact force. This property enables the rubber buffer block to quickly deform and absorb energy when impacted by external force, thereby reducing the vibration and impact of equipment or personnel, and rubber also has good wear resistance.
