Adopt and above-mentionedly to arrange further again, second back-moving spring is arranged between the upper end of lever and shell, the arm of force produced when lever rotates around the first axle body due to lever upper end is the longest, therefore the restoring force of the second back-moving spring can be made maximum, thus making circuit breaker energy quick acting switching-off, service behaviour is better; This second back-moving spring mounting means, it is firm to locate, and can not come off.
Further setting more of the present utility model: described snap close is that plastics are made, and the first axle body is that metal material is made, and snap close is directly set on the first axle body.
Adopt and above-mentionedly further to arrange again, this snap close, the first axle body set-up mode, make snap close easier for installation, and the frictional force between snap close and the first axle body is little, and snap close can Rapid reset, threads off quicker with tripping.
Further setting more of the present utility model: the sidewall of described the second axle body is provided with annular boss, and annular boss is positioned at inside the outline of tripping, and described tripping and annular boss are conflicted.
Adopt and above-mentionedly further to arrange again, the annular boss of setting can make tripping not need directly to contact with lever, substantially reduces contact-making surface, thus reduces frictional force, effectively improve the movement velocity of tripping; And annular boss can strengthen the intensity of the second axle body, extend its useful life.
