Preferably, the angle between the bearing of trend of described first connecting portion and the bearing of trend of described second connecting portion is acute angle.
Preferably, the angle between the bearing of trend of described first connecting portion and the bearing of trend of described second connecting portion is less than 60 °.
Preferably, the angle between the bearing of trend of described first connecting portion and the bearing of trend of described second connecting portion is 58 °.
Preferably, described first connecting portion has the first end away from connecting body, first end of described first connecting portion is provided with manhole, and described second connecting portion has the first end away from connecting body, and the first end of described second connecting portion is provided with manhole.
Preferably, the length of described first connecting portion is not more than the length of described second connecting portion.
Preferably, the length of described first groove is not more than the length of described second groove.
Beneficial effect: compared with prior art, it has following beneficial effect to the utility model:
The utility model primary cut-out connecting rod, due to bearing of trend and second connecting portion of the first connecting portion bearing of trend all with the axes normal being connected body, and between the bearing of trend of the bearing of trend of the first connecting portion and the second connecting portion, be angularly arranged so that connecting rod is in the process of action, the power that first connecting portion and the second connecting portion bear can equably to being connected body conduction, make connecting rod integral stress equalization, thus structure is more stable not yielding, fixed, improve useful life, and then improve the dependability of primary cut-out, ensure that the working effect of primary cut-out.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of specification, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
