And when the device is in use, if there is a water leakage at the connection of the water pump 5, the water drops fall into the inner cavity of the collection tank 91, which can make the expansion block 92 expand when encountering water. Then the movable plate 93 can move upward.

S2: During the processing, the water pump (5) can be started to provide cooling liquid to the spindle body (2). After the cooling liquid is sprayed out, impurities in the cooling liquid can be filtered through the filter (20). S3: When the coolant enters the inner cavity of the guide tube, the worm wheel (73) can be rotated.
