Square opening position forms one first recess, and the first recess end forms spacing circular arc, at the top of lever by spacing block set with
Handle is formed and compressed, and the spacing circular arc split in the fit circular arc and support below lever, the mosaic is provided with " work " word axle,
Being somebody's turn to do " work " word axle includes middle-end part and both sides positive stop end, and mosaic is circumferential spacing with being somebody's turn to do " work " word axle middle-end part composition, and
Mosaic is formed with being somebody's turn to do the axial limiting of " work " word axle middle-end part by both sides positive stop end；The second recess is formed at housing,
Second recess include the contact surface of housing first, housing first close on face, the contact surface of housing second, housing second close on face with
The contact surface of housing the 3rd, place forms a filling block below support, and the filling block closes on including the contact surface of support first, support first
Face, the contact surface of support second, support second close on face and the contact surface of support the 3rd, the contact surface of support first and housing first
Contact surface fits, and the contact surface of support second fits with the contact surface of housing second, and the contact surface of support the 3rd connects with housing the 3rd
Contacting surface is with fitting, and support first closes on face and housing first and closes on face and mutually close on it and is shaped as reversely consistent, support second
Close on face and housing second close on face mutually close on its be shaped as it is reversely consistent.
Above-mentioned moulded case circuit breaker, it is described by handle, lever, support and housing coordinate and position restriction,
The intensity of support can more preferably be ensured, being threaded off and closed a floodgate due to moulded case circuit breaker is both needed to handle motion, handle and lever phase
Even, connection of the support between bridge composition lever and housing；Because the mating surface that support is fixed at housing is pair
Support is axially fixed with housing, and its radial direction is not fixed, fine clearance therebetween also be present, passes through the fine clearance
When can reduce dropout or close a floodgate, there is the excessive probability that damage is caused to moulded case circuit breaker of propulsive thrust, could be applicable to
The fine setting of moulded case circuit breaker.
The utility model is further arranged to, and handle two sides opening position is provided with support, and support shape at two sides
Shape is identical.
Above-mentioned moulded case circuit breaker, handle two sides opening position are provided with equal support, and support at two sides
Shape is identical, can ensure the reasonability of structure by the setting, and this is simple in construction, and intensity is good.
