[0002] With the development of society and the improvement of people's living standards, almost every family has a private car for the convenience of self-driving travel. However, the emergence of a large number of private cars has led to very congested traffic, which has brought trouble to people's travel. Therefore, people in urban areas usually choose bicycles, motorcycles or electric bicycles to travel to alleviate traffic congestion. The brake lines of bicycles, motorcycles and electric bicycles need to be oiled with an oiling machine during maintenance to avoid accelerated damage of the brake lines due to excessive friction. The oil pipes need to be cut during processing for use.
