[0002] A relay is an electrical appliance that connects or disconnects a circuit based on changes in physical quantities such as voltage, current, temperature, speed or time. The main functions of a relay are protection and control. Although there are many types of relays, they can generally be divided into two categories: protection relays and control relays. Common relays include thermal relays, electromagnetic relays, time relays, temperature relays and speed relays. As an electronic control device, relays have been widely used in automated control circuits, and the gap and overtravel between the moving and static reeds in the relay are one of the very important performance parameters of relay products.

In addition, as the size of relay products is getting smaller and smaller, the control of these performance parameters is becoming more and more stringent. Due to the rapid increase in production capacity, the traditional manual adjustment method can no longer meet the needs of large-scale production. Therefore, a machine capable of adjusting the relay adaptive parameters is needed to greatly improve the actual production efficiency. Utility Model Content
