Branch quick connection device of water distributing and collecting device and water distributing and collecting device

The invention provides a branch quick connecting device of a water distributing and collecting device and the water distributing and collecting device, and relates to the technical field of heating devices. Through the arrangement of the special-shaped mounting opening, the positioning part on the branch can be clamped into the special-shaped mounting opening for limiting, due to the arrangement of the corner, the positioning part on the branch can be prevented from being separated from the special-shaped mounting opening, efficient and stable mounting of the branch and the branch quick connecting device is achieved, the problem of over-screwing does not exist in the process, and the mounting efficiency is improved. And the pipe orifice of the pipeline can be prevented from being damaged in the mounting process. Besides, the quick connecting piece core body is contained in the quick connecting piece shell, the quick connecting piece core body is provided with a plurality of first grooves, and the quick connec
