Beschreibung
Zusammenfassung:	The invention provides a sealing plug and a sealing structure of a workpiece, which comprises the sealing plug, wherein a saw-tooth-shaped bulge is arranged on a peripheral wall of the sealing plug; and when the sealing plug is mounted in a hole in an interference manner, the saw-tooth-shaped bulge has elastic deformation and/or plastic deformation, so as to seal the hole. According to the sealing plug provided by the invention, the saw-tooth-shaped bulge is arranged on the peripheral wall of the sealing plug; when the sealing plug is mounted in the hole to be sealed in the interference manner, the saw-tooth-shaped bulge is extruded to have the elastic deformation and/or the plastic deformation, and then is tightly fitted with a hole wall, so that the hole is sealed and the sealing effect is good; in an assembling process, only the sealing plug needs to be plugged into the hole to be sealed and the sealing plug is very convenient and is not easy to deform; and meanwhile, the sealing plug is simple in structur
