Specifically, when cooling or cleaning is required, the electromagnet is energized to generate magnetic force to attract the blocking block to overcome the force of the blocking spring, so that the blocking block is away from the bottom of the shower pipe, thereby opening the water channel, and the water flows through the shower pipe to the vicinity of the installation head, effectively cooling and cleaning the tool. When cooling or cleaning is not required, the electromagnet is powered off, and the blocking spring pushes the blocking block to reset, re-blocking the shower pipe to prevent water leakage. At the same time, the electromagnet can also adsorb the tool when it is started, thereby improving the stability of the tool installation. This design not only improves the efficiency of cooling and cleaning, but also avoids waste of water resources and ensures the stable operation of the machine tool.
