During filling, one end of the storage cylinder is closed, making it difficult to judge the amount of grease in the storage cylinder, resulting in the problem of too little grease in the storage cylinder after the filling operation is completed. Moreover, since the storage cylinder is sealed during use, the amount of grease stored in the storage cylinder cannot be intuitively judged during use. The amount of grease to be injected into the equipment depends on the operator's experience, resulting in the problem of insufficient grease injection in some equipment. Utility Model Content
