Because the inner barrel water outlet needs to be positioned accurately relative to the position of the ejector rod fixed on the outer barrel to ensure the sealing effect, a positioning pin driving mechanism for positioning the inner barrel in the circumferential direction is added, when the water outlet needs to be opened, the positioning pin stretches out, the inner barrel slowly rotates until the positioning pin is clamped into a unique positioning hole at the bottom of the inner barrel, at the moment, the position is the position of the inner barrel bottom water outlet aligned with the ejector rod, and the ejector rod stretches out and jacks up the water outlet.
