1. A three ball pin-type coupling, comprising:
a first connector and a second connector which are non-rotatably connected;
the first connector comprises a three shaft pin assembly, three raceway assemblies and a cage assembly;
the three shaft pin assembly comprises a shaft and three ball rings which surround the shaft and are arranged at intervals in a circumferential direction of the shaft; each said ball ring is connected to one of the raceway assemblies; the cage assembly defines a position of the raceway assemblies in the circumferential direction;
the raceway assemblies are configured to provide an elastic force between the ball ring and the cage assembly; and
when the ball ring displaces relative to the cage assembly in the circumferential direction, two sides of the raceway assembly in the circumferential direction remain abutted against the cage assembly.
