[0002] The leakage protection circuit breaker has overload, short circuit and leakage protection functions, that is, it has the functions of a circuit breaker and a leakage protector. Therefore, the leakage protection circuit breaker is a commonly used protection device in electrical circuits, and is widely used in mobile electrical equipment and handheld power tools; electrical equipment installed in humid, highly corrosive and other harsh places; electrical construction machinery and equipment at construction sites; socket circuits in buildings such as schools, enterprises, and residences; underwater lighting equipment in swimming pools, fountains, and baths; power supply lines and equipment installed in water; electrical medical equipment in hospitals that directly contact the human body, etc.

[0010] In the above structure, the second torsion spring can be further limited by providing a limiting column, thereby further improving the stability of the second torsion spring.

[0011] The utility model is further configured that a sleeve hole adapted to the second fixing column is opened in the axial direction of the limiting column.
