According to the device, when a first gear seat moves a knocking rod to trigger an ejector rod, the ejector rod pushes a control button electrically connected with a liquid supply pump to enable the liquid supply pump to work, the liquid supply pump is guided to the gear seat needing to be lubricated through a lubricating guide groove, and a liquid control mechanism is effectively lubricated in good time; the pressing wheels on the adjusting frame extrude the cooling pipes according to the layout design of the cooling pipes, and the flowing sectional area of cooling liquid is changed so as to adjust the flow speed.
