Only the passage of the smooth pad 108 is required to achieve rapid clamping of the external pipeline. The design structure is simple, which solves the problem that the clamping connection part needs to be pressed by the staff to align with the external pipeline during clamping, the connection process is subject to large resistance, and the clamping connection part cannot be quickly clamped.
