This utility model belongs to the technical field of filling equipment, specifically a lubricating grease filling device, including a filling barrel with a support rod fixedly connected to its outer side. By setting up a fixed pipe, an adjusting pipe, a sealing plate, a toothed plate, and gears, during filling, the packaging barrel is placed under the fixed pipe.
