Circuit breakers are widely used in the industrial field and are generally used for infrequent circuit switching. Common circuit breaker operating mechanisms are divided into manual circuit breaker operating mechanisms, automatic circuit breaker operating mechanisms, and manual and automatic combined circuit breaker operating mechanisms.

[0003] At present, a Chinese patent with publication number CN115763174A discloses a circuit breaker operating mechanism, including a manual energy storage component, an automatic energy storage component, a manual release component, an automatic release component, a chain switching component and a rocker component arranged on a support seat, characterized in that: the rocker component is rotatably connected to the support seat, a main shaft is arranged on the support seat, the main shaft passes through the rocker component, and the rotation of the main shaft drives the rocker component to swing back and forth with the support seat as the center.

A connecting through hole 45 is provided on the rotating block 41 along the vertical direction, and the connecting through hole 45 passes through the opposite ends of the rotating block 41. The rotating block 41 is set in the rotating groove 51 of the connecting plate 5, and the mounting through hole 52 on the connecting plate 5 is connected with the connecting through hole 45 on the rotating block 41. The connecting through hole 45 and the mounting through hole 52 are both provided with a rotating shaft 6 . The rotating block 41 is rotatably disposed in the rotating groove 51 via the rotating shaft 6 . The rotating groove 51 extends from a side of the rotating block 41 away from the rotating shaft 6 .

[0035] Reference Figure 3 , Figure 4 and Figure 6 , the length of the rotating block 41 is smaller than the length of the rotating groove 51, and a hemispherical adjusting block 46 is fixedly connected to the top of the rotating block 41. Two adjusting grooves 53 are parallelly provided on the inner top wall of the rotating groove 51. When the adjusting block 46 is embedded in the adjusting groove 53, the adjusting block 46 fits with the inner wall of the adjusting groove 53. A receiving groove 47 is provided at the bottom end of the rotating block 41. The receiving groove 47 is coaxial with and connected to the connecting through hole 45, and the diameter of the receiving groove 47 is larger than the diameter of the connecting through hole 45. A tightening spring 7 is sleeved on the rotating shaft 6, one end of the tightening spring 7 is tightened against the inner bottom wall of the rotating groove 51, and the other end extends into the receiving groove 47 of the rotating block 41 and is tightened against the inner bottom wall of the receiving groove 47.

[0039] The implementation principle of a switching device of an electric operating mechanism in the embodiment of the present application is: before installation, the rotating block 41 is first turned so that the adjustment block 46 is embedded in the corresponding adjustment groove 53. The first marking point 8 and the second marking point 9 set on the bottom surface of the support seat 1 facilitate the operator to intuitively observe the position state of the pressing rod 43. Since the output end position of the pressing rod 43 can be directly adjusted, the device can be applied to circuit breakers with switches in different positions, without the need to re-customize the tooling, thereby expanding the scope of application of the device.
