Beschreibung
Zusammenfassung:	The taper sleeve is a cylindrical part, the two ends of the taper sleeve are a closed end and an open end respectively, the outer side rotation surface of the cylinder wall of the taper sleeve comprises a first outer side surface and a second outer side surface which are connected in a left-right mode, and the inner side rotation surface of the cylinder wall of the taper sleeve comprises a first inner side surface and a second inner side surface which are connected in a left-right mode. The outer first surface and the outer second surface are respectively a cylindrical surface and a conical surface, the diameter of the cylindrical surface is smaller when the cylindrical surface is closer to the open end, the inner first surface and the inner second surface are conical surfaces, the diameter is larger when the cylindrical surface is closer to the open end, and the taper of the inner first surface is smaller than that of the inner second surface; the taper sleeve pin shaft assembly comprises a pin shaft and the
