The inner cavity of the base 1 is fixedly installed with a cooling pipe 29, and there are two anti-skid transmission belts 19, which are respectively movably sleeved on the surfaces of the blanking rotating plate 20 and the rotating tube 27. The bottom end of the plug-in base 1 is a rectangular cavity, and two circular holes are provided at the bottom end of the plug-in base 1.

[0035] Then, the plug connector 22 is cooled and dissipated through the cooling pipe 29, and then the rotating pipe 27 is driven to rotate through the transmission shaft 18, and then the three-head conveying roller 26 is driven to rotate through the rotating pipe 27. Through the rotation of the three-head conveying roller 26 and the squeezing of the connecting pipe 28, the cooling water in the inner cavity of the cooling box 23 is transported along the connecting pipe 28 to the inner cavity of the cooling pipe 29 through the negative pressure in the inner cavity of the connecting pipe 28, and then the cooling water is made to flow in the inner cavities of the cooling pipe 29 and the conveying sleeve 30, so that the cooling water absorbs the heat generated when the plug connector 22 is connected to the wire, and flows back to the inner cavity of the cooling box 23 for heat dissipation.
