Being provided with pitman shaft installing hole and extension spring installing hole on blade, the two ends of pitman shaft are plugged on graphite vanes pitman shaft respectively and install
In hole, it is fixed in extension spring installing hole by one end, the extension spring that the other end is connected with pitman shaft, by two graphite vanes and connecting rod
Axle connects into entirety.
Further, the extension spring pin-and-hole being additionally provided with in graphite vanes with connecting bottom extension spring hole, one end of extension spring with
The extension spring installed by extension spring pin-and-hole is hung pin and is connected.
The other end of extension spring and the hangers on pitman shaft or connector mounting.
The good effect that this utility model produces due to employing said structure is significant: i.e. owing to using solid stone
Ink blade and a kind of brand-new mounting structure using extension spring graphite vanes to be fixed on pitman shaft, improve fault-resistant energy
Power, constitute tight entirety while, assembling is also easily simple.
