By setting the adjustment structure 3, all the operating levers 2 can be automatically and simultaneously pulled. In an emergency, the power supply can be quickly cut off to protect the safety of equipment and personnel, enhance the responsiveness of the system, and in a narrow space environment, the operating lever 2 can be conveniently switched, which improves the flexibility of the operator. Sliding holes 311 are provided on both sides of the fixed seat 302. The center of the sliding hole 311 is coaxial with the axis of rotation of the rotating shaft 303. The inner wall of the sliding hole 311 is slidably connected with a sliding rod 312. One end of the sliding rod 312 is fixedly connected to one side of the connecting plate 304. During the rotation of the connecting plate 304, the sliding rod 312 fixed on the connecting plate 304 will slide along the inner wall of the sliding hole 311, thereby improving the rotation of the connecting plate 304.

The connecting plate 304 drives the driving plate 305, and then the driving plate 305 pushes the operating rod 2 during the rotation. When the operating rod 2 is opened or closed, the electric push rod 309 is started again to drive the gear block 310 to separate from the gear hole 306. At this time, the coil spring 314 can quickly drive the driving plate 305 away from the operating rod 2. When the lever 304 is unlocked, the lever 304 is unlocked and the handle 312 is unlocked, and the handle 312 is unlocked. The stability of the sliding rod 312 during movement is improved. In addition, the rubber pad 316 can increase the softness of the side of the driving plate 305 close to the operating rod 2, thereby preventing the driving plate 305 from squeezing and damaging the operating rod 2. The protective cover 315 can cover and protect the servo motor 308, thereby preventing the servo motor 308 from being damaged by collision. Finally, by providing a reinforcing rib 317 made of aluminum alloy at the connection between the fixed plate 301 and the circuit breaker body 1, the strength of the connection between the fixed plate 301 and the circuit breaker body 1 is improved.
