[0018] according to Figure 1 ~ Figure 4 The specific structure of the present invention will be described in detail. The eccentric self-locking nut includes a lower body 1 with an eccentric boss at the upper part and an upper body 2 with an eccentric hole at the lower part. The upper and lower bodies 2, 1 and the connecting bolt 10 have the same internal threads and are on the same axial centerline. on. The eccentric boss of the lower body 1 and the eccentric hole of the upper body 2 are tightly connected and fixed by a thin-walled sleeve 4 with a frustum. In order to meet the needs of different elastic deformations and the size of the friction coefficient formed, the thin-walled sleeve with frustum 4 can be made of metal or non-metallic materials in an integral structure, a split structure, or a combined structure composed of at least two sleeves. . The main function of the above-mentioned connection and fixation has two points: one is to generate a certain initial frictio...
