Second actuator 22 promotes the second guide post 23, then promotes and loads lever 30 around loading in lever 30
The bearing in portion rotates, and then loads to two power bars；
When the transform linear motion of the first actuator 12 is that two power bar one end are around the other end (the i.e. first lining 51
Center) rotary motion, the actuating length of the i.e. first actuator 12 is corresponding with two power bar pendulum angles；Along with
The swing of two power bars, the second actuator 22 applies corresponding thrust or pulling force to two power rod member imposed loads；As
This just achieves the complex conditions loading and swinging.
Thus, this utility model is also rationally effectively combined by introducing enough kinematic pair quantity, as
Above-mentioned swing actuation mechanism 10, loading actuation mechanism 20, the design of loading lever 30 so that trial stem
50 (such as two power bars) are by while axial push-pull load, moreover it is possible to according to actually used Work condition analogue trial stem
The swing of 50；The most really, more effectively demonstrate the Anti-pull-press performance of two power rod members, also demonstrate
The fatigue behaviour of the rubber bushing at rod member two ends.Additionally, swung by Tensile or Compressive Loading and needs for similar
Rod member, this utility model is equally applicable.
Above disclosed only preferred embodiment of the present utility model, can not limit this with this certainly
The interest field of utility model, the equivalent variations therefore made according to this utility model claim, still belong to
The scope that this utility model is contained.
