As preferably, above-mentioned connecting rod is provided with articulated elements, and the operating grip of articulated elements and circuit breaker is hinged.Simple by the articulated elements syndeton, as to make things convenient for parts such as connecting rod processing and manufacturing.
As preferably, described impeller is a roller.Overhead gage on roller and the connecting rod rolls with lower baffle plate and contact, can handled easily, avoid member to wear and tear.
The output shaft of above-mentioned motor circumferentially fixedly installs connecting plate.
As preferably, described cage is provided with support, and support is put on the shelf and is provided with guide rod, and described connecting rod cooperates to slide up and down with guide rod by guide hole and is connected.Support is a metal sheet, and is simple in structure like this, use reliable, the convenient manufacturing.
As preferably, the metal sheet that described connecting rod, overhead gage, lower baffle plate and guide hole are formed in one.Simple in structure like this, use reliable, the convenient manufacturing.
Above-mentioned circuit breaker is the high breaking circuit breaker; Above-mentioned motor is a permagnetic synchronous motor.
The utility model is owing to adopted above technical scheme; the creationary operating mechanism that has used idler-wheel connecting-rod to promote; realized electric operating and manual operation automatic switchover by structural design in protector inside; thereby when carrying out manual operation, just can not drive motor so again and rotate the assurance fail safe, have advantages such as simple and reasonable, that use is reliable, easy to operate.Solved because the protector volume structure that electromechanical integration is brought is bigger usage space demanding shortcoming and make problem such as the easy fault of operating mechanism because of frequent movement.
