[0002] Grinding and polishing machines are used in many industries. They are often used to prepare metal samples, polymer samples, ceramic samples or similar samples for further experiments, such as metallographic experiments. During the grinding process, consumables such as sandpaper and flannel need to be fixed on the grinding disc, and the prepared grinding liquid can be added to the flannel. The sample will generate heat during the grinding process, so the sample needs to be cooled and cleaned. The known Chinese utility model patent CN215281450U provides a grinding and polishing machine for detecting the pressure of a handheld sample. It uses a rotary water nozzle set on a base, which can rotate or adjust the water volume so that the liquid outlet enters or leaves the grinding and polishing station to complete the cooling and cleaning of the sample. However, during the rotation of the grinding disc, the rotary water nozzle will interfere with the grinding head on the grinding and polishing machine or the sample will not be cleaned properly, which is inconvenient to use. Therefore, it is urgent to modify the existing rotary water nozzle part. Utility Model Content
