[0002] Retrofit circuit breaker units play a vital role in electrical system retrofits. With the continuous advancement of technology and the upgrading of electrical equipment, retrofitting electrical systems has become a common practice. As key devices for circuit safety, retrofit circuit breaker units can promptly cut off power in the event of abnormal conditions such as overloads and short circuits, protecting electrical equipment and personnel.

[0003] However, current retrofit circuit breaker units have numerous drawbacks. First, they typically require tools like screwdrivers and wrenches to tighten and remove wires, making the operation extremely cumbersome and inconvenient. This inconvenience also hinders quick assembly and disassembly of wires. In some emergency situations, wires need to be quickly disassembled and assembled to restore circuits or perform repairs, but current retrofit circuit breaker units cannot meet this need. This not only wastes time but can also have serious impacts on production and daily life.

[0004] In summary, the current retrofit circuit breaker unit has shortcomings such as cumbersome operation, waste, and poor convenience, and is in urgent need of improvement and innovation. Therefore, we have developed a retrofit circuit breaker unit. Utility Model Content

[0034] See also Figures 1 to 4 As an embodiment of the present utility model: in actual use, the movable push rod 26 is driven to rotate by rotating the square frame 204, and the movable push rod 26 drives the rectangular block 203 to rotate through the docking round block 29, so that the rectangular block 203 is aligned with the rectangular opening 28, and then the movable push rod 26 is pulled forward by rotating the square frame 204, so that the docking round block 29 and the rectangular block 203 are pulled out from the circular opening 27 and the rectangular opening 28 respectively.
