During the oil change process, the two sets of flow meters 24 are provided to facilitate accurate measurement and control of the oil flow rate during the oil change process, so that the amount of new lubricating oil injected is the same as the amount of old lubricating oil extracted, ensuring that the amount of new oil added to the reducer is appropriate to avoid excess or deficiency, making the oil intake more accurate and controllable. The design of the telescopic hose 23 increases flexibility, making it easy to connect the oil nozzle 25 to the reducer refueling port at different positions and heights, thereby improving the versatility and practicality of the device. The control panel 5 facilitates real-time observation of the oil flow rate monitored by the flow meter 24 and the working status of the oil pump 21, thereby facilitating accurate control of the oil change amount and adjustment of the oil change speed.
