1. A floating joint and retainer connection device with pressure relief structure, comprising:
a fixed retainer having a first side and a second side located opposite to each other and internally defining a receiving space located between the first and the second side; the first side being an open side and the second side being a closed side provided with a through hole; and the through hole being communicable with the receiving space;
an adaptor joint having an engaging end and a fitting end, and including a buffering section located and extended between the engaging end and the fitting end; the fitting end of the adaptor joint being extended into the receiving space of the fixed retainer to project outward from the through hole; and the adaptor joint including a shoulder portion formed at a junction of the engaging end and the buffering section;
a slidable washer being fitted on an outer surface of the fitting end of the adaptor joint;
an elastic element being fitted around the outer surface of the fitting end of the adaptor joint and located between the second side of the fixed retainer and the slidable washer;
a fixing element being fitted on the outer surface of the fitting end of the adaptor joint, such that the adaptor joint is limited from moving axially relative to the fixed retainer but radially displaceable relative to the fixed retainer;
an abutting spacer being fitted on around the buffering section of the adaptor joint and having one side formed into an axially protruded section for abutting against the slidable washer; and
a spring being fitted on an outer surface of the buffering section with two ends pressing against one side of the abutting spacer opposite to the axially protruded section and the shoulder portion of the adaptor joint, respectively.
