The elastic gasket 9 is made of elastic material and can provide a certain pre-tightening force during installation. When the equipment is working, if vibration occurs, under the elastic effect of the elastic gasket 9, the fixing bolt 6 can be prevented from rotating, causing the connection between the fixing bolt 6 and the fixing nut 10 to become loose, thereby playing a role in preventing vibration and loosening.
