The outlet port 2 1 2, 2 2 2 is configured to open the second flow path and the outflow end 1 2, and when the force is stopped and the pressing handle 4 is pulled, the steel ball 2 4 1 , 2 5 1 is subjected to the spring The elastic recovery force of 2 4 2, 2 5 2 resets and closes the high pressure and the low pressure outlet 2丄2, 2 2 2, and prevents the butter from being withdrawn again. [0012] According to the present invention, the outlet pressures of different heights and lows can be generated by two flow passages having different cross-sectional areas, and the movable pivot 6 can freely switch the pivotal position as needed to adjust the output state to conform to various uses. Demand, however, because the customary butter has less design of the drainage unit and the normally closed valve, the structure is simpler and the processing procedure is simpler, so the production cost can be reduced.
