Portion, the division lever rotation are arranged between two straight line portions.
In the above scheme, the support plate is equipped with a fillet part, and the fillet part along itself vertical direction to extension
It stretches to form arc feet, the arc feet is fixed in the arc sections.
In the above scheme, the support plate extends outward to form plate, the number of the plate along itself vertical direction
Be two, and be separately positioned on the fillet part it is tangential on, the plate is fixed in the straight line portion.
In the above scheme, the support plate is equipped with symmetrical locating notch, the locating notch and the engaging slot
Shape is agreed with.
In the above scheme, the support plate is equipped with several fixation holes.
In the above scheme, the radian of the arc sections is identical as the radian of the bottom end of the stabilizer blade.
In the above scheme, the installation fixed with the shell is respectively provided on the left support and the right support
Frame, the engaging slot are arranged on the installing frame.
The present invention, timbering material plastics can eliminate breaker disjunction instead of the common metal material of similar product
The adverse effect that the magnetic loop that metallic support generates in journey moves towards electric arc；It can avoid the attached of the metallic particles that breaking course generates
, influence mechanism action performance；It can avoid unfavorable shadow of the vortex to breaker temperature rise model of galvanization metallic support generation
It rings；Plastic stent uses injection molding process, the simple easy processing of process, and precision high, overcomes the metallic support of cold-punching molding
Manufacturing procedure is more, defect that error is big；It is simultaneously the defect for avoiding plastic material lower hardness, part is embedding on plastic stent
Enter the support plate of piece of metal material, increased the hardness of plastic stent and division lever contact face, accelerates division lever and branch
The relative rotation speed of frame is conducive to improve breaker breaking capacity.
