[0002] A limiter is a safety protection device that is mainly used to limit the range of motion or position of mechanical equipment. It can prevent the equipment from exceeding the predetermined working range, thereby avoiding equipment damage, accidents or personal injury. Limiters are widely used in various mechanical equipment, such as cranes, lifts, machine tools, automated production lines, etc. The working principle of limiters is generally based on the triggering of sensors or switches. When the mechanical equipment moves to the predetermined position, the sensor or switch in the limiter will be triggered, thereby sending a signal to the control system to stop the equipment or change the direction of movement. In this way, the limiter can effectively protect the safety of equipment and personnel.
[0003] As an important safety protection device in mechanical equipment, the normal operation of the limiter is of great significance to the stable operation of the equipment.

In order to solve this problem, the limiter needs to be lubricated regularly to reduce friction and extend its service life. However, the traditional oiling device is often large in size, which is not only inconvenient to operate, but also inconvenient to carry. In addition, there are oil leakage and overflow during oiling, which wastes oil and affects the oiling effect. Utility Model Content
