Beschreibung
Zusammenfassung:	The invention relates to the technical field of mechanical connection structures and particularly discloses a fastening structure. The fastening structure comprises a bolt and a washer which are matched for use, the bolt is provided with a spherical protrusion, and the spherical protrusion is provided with an outer spherical surface; the washer sleeves the spherical protrusion, is of a hollow structure and is provided with an inner spherical surface, and the inner spherical surface is matched with the outer spherical surface so that the washer can freely rotate to fit the matching face of a connected part. The bolt and the washer are matched through a spherical surface so that the washer can freely rotate, the flange face of the washer fits that of the connected part accordingly, the axialforce of a double-screw bolt acts on the connected part through the washer, and the connected part is fastened. According to the fastening structure, the demand for the perpendicularity of the matching face of the connected
