a heat shrink fixed exhaust pipe, including a connecting tube, an exhaust soft tube, an exhaust soft tube having one end mounted on the connecting tube, a connecting tube and an exhaust soft tube between the exhaust soft tube and the connecting tube The overlap is completely covered and a ring-shaped heat shrinkable sleeve can be heated. The ring-shaped heat shrink sleeve is subjected to heat shrinkage, and the exhaust soft tube is finally compressed on the outer wall of the connecting tube and the end face of the connecting tube, thereby achieving a fixed connection.
