Installation time, while solving the problems, such as that two parts, in the main engine plants' fit quality that may deposit of assembling, reduce main engine plants
Assembly cost；Riveting process in assembly uses all directions round button riveter skills, instead of six side's sleeving and riveting techniques so that splicing sleeve with
Pulling-out force after pressure hose riveting brings up to more than 8000N by 5000N, the pulling-out force after shaft core and cylinder lever connecting rod riveting by
8000N brings up to more than 11000N, at the same avoid junction stress and deformation it is uneven caused by clamping stagnation, it is stuck situations such as
Appearance；Rocking arm is provided with hole, and the end on the hole and control stick is welded again after being coordinated, it is ensured that rocking arm with
Control stick weld strength reaches more than 5000N；Flexible axle is changed to hemisphere radial type and connects with base junction by fixed connection, solution
Shaft core of having determined and the premature wear of the caused shaft core of splicing sleeve friction, improve the service life of flexible axle shaft core；Also, it is pressure-resistant soft
Pipe uses sandwich construction with shaft core, and their cooperation can greatly reduce resistance and idle stroke, improves load efficiency and uses the longevity
Life.
To sum up, operating mechanism, the part of pushing-pulling flexible shaft two are combined into a module by control rod assembly of the present invention, and reduction is assembled into
This, it is to avoid there is assembling matching problem, in combination with all directions round button riveter skill enhancing junction pulling-out forces, it is ensured that use the longevity
Life；Pressure hose coordinates with shaft core sandwich construction, reduces resistance and idle stroke.
