It is further provided that: the operating handle is provided with installation reinforcing ribs for installing the elongated handle, and the elongated handle is provided with an installation block.

Through the above technical solution, the installation of the reinforcing rib can increase the bending strength of the operating handle, and also serve as a mounting bracket for the extended handle when the hinged rotation plane of the operating handle and the circuit breaker body is perpendicular to the hinged rotation plane of the operating handle and the extended handle. In use, the installation block on the extended handle is the installation part matched with the installation reinforcement rib.

It is further provided that: the operating groove on the operating handle is obliquely U-shaped.

Through the above technical solution, when the operator is operating the high operating handle at the bottom, the operating rod can be easily snapped into the oblique U-shaped operating groove.

It is further provided that: the operating groove on the elongated handle is barb-shaped.

Through the above technical solution, when the hinged rotation plane of the operating handle and the circuit breaker body is parallel to the hinged rotation plane of the operating handle and the extension handle, it is necessary to rotate the extension handle from the top of the The position-limiting protrusion bears against the top of the supporting rib, so the operating slot is set into an undercut shape, which can turn over a considerable angle without the operating rod falling off from the operating slot.

It is further provided that: the operating groove on the elongated handle is obliquely U-shaped.

Through the above technical scheme, when the hinged rotation plane of the operating handle and the circuit breaker body is perpendicular to the hinged rotation plane of the operating handle and the extension handle, since the rotation plane of the extension handle forms a small angle with the horizontal plane, even if it is an oblique U-shaped The operation rod will not easily fall out of the operation groove, and the oblique U-shaped groove can make the operation rod snap into the operation groove more easily.

To sum up, the beneficial effect of the utility model is that the operating rod can be easily snapped into the operating groove, and the turning force arm can be increased by extending the handle to reduce the force required for turning.
