Composite slow-release miniature overflow gutter inlet shaft

The utility model discloses a composite slow-release miniature overflow gutter inlet shaft which comprises a first shaft connecting buckle A end, a slow-release shaft, a hidden shaft A and a hidden shaft B. The slow-release shaft is connected to the lower portion of the first shaft connecting buckle A end, and shaft slow-release holes are formed in the periphery of the outer wall of the slow-release shaft. A second shaft connecting buckle B end is arranged below the hidden shaft A. A hidden shaft B is connected to the lower portion of the hidden shaft A. Through the arrangement of the shaft slow-release hole and the slow-release shaft, part of rainwater is preferentially and slowly discharged into the overflow well through the slow-release shaft at the initial stage of rainfall, and when the rainfall is increased, the shaft slow-release hole and the slow-release shaft discharge water at the same time, so that the drainage capacity of the micro overflow well is improved, and the number of the micro overflow we
