Orbiting scroll plate driving assembly and scroll compressor

An orbiting scroll plate driving assembly, comprising:

• a main shaft,
• a tail driving shaft, and
• an eccentric shaft sleeve, the tail driving shaft being eccentrically connected to the main shaft, and the eccentric shaft sleeve being rotatably sleeved on the tail driving shaft;
• wherein the orbiting scroll plate driving assembly further comprises a limiting portion, the limiting portion is disposed on the tail driving shaft, the limiting portion comprises an annular body, and the annular body is disposed on an end of the tail driving shaft,
• the limiting portion is provided with a first limiting portion groove, the eccentric shaft sleeve is provided with a first eccentric shaft sleeve protrusion, the first eccentric shaft sleeve protrusion is correspondingly inserted into the first limiting portion groove, and a circumferential size of the first limiting portion groove is larger than a circumferential size of the first eccentric shaft sleeve protrusion;
• and
• an outer diameter of the annular body is less than or equal to an outer diameter of the tail driving shaft.
