Floating joint and retainer connection structure

A floating joint and retainer connection structure comprising:

• a fixed retainer having a first side and a second side and internally defining a first receiving space between the first and the second side;
• the first side being in an open state while the second side having a through hole provided thereat;
• and the through hole being communicable with the first receiving space;
• an adaptor joint having a guiding section and a pipe connecting section;
• the guiding section internally defining a second receiving space and having a free end in an open state with a beveled guiding surface formed along a rim of the free end;
• the pipe connecting section including a pipe fitting end and an engaging end, and internally defining a flow passage communicable with the second receiving space;
• and the pipe connecting section of the adaptor joint being extended through the first receiving space to project from the through hole of the fixed retainer;
• a retaining element fitted on around an outer surface of the pipe connecting section of the adaptor joint to limit the adaptor joint from moving axially relative to the fixed retainer while allowing the adaptor joint to move radially relative to the fixed retainer;
• and
• a first washer fitted on around the outer surface of the pipe connecting section of the adaptor joint with one side of the first washer attached to an outer surface of the second side of the fixed retainer.
