Abstract: A damping spindle mechanism includes a spindle, a sleeve, a housing and a blade. The sleeve is coupled to the spindle; the housing is disposed with a chamber, one section of the spindle threaded with the sleeve is assembled in the chamber of the housing to form a closed chamber; the close chamber is filled with damping oil and is separated to a first chamber body and a second chamber body by the sleeve; the sleeve is disposed with a first passage connecting the two chamber bodies in the axial direction; wherein the blade is of ring shape or arc shape coupled to the internal wall surface of the housing, the blade is disposed with a deformable first thin wall. When the blade moves towards the second chamber body, the first thin wall deforms towards the internal wall surface of the housing.
