In figure: the first fixed disk of 1-, the second fixed disk of 2-, 3- cylindrical connector, 4- mounting hole, 5- rotary shaft, 6- empennage,
The first plane of 7-, the second plane of 8-.
Specific embodiment:
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment
It is only used for explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.
In addition, the description for being related to " first ", " second " etc. in the present invention is used for description purposes only, and cannot understand
For its relative importance of indication or suggestion or implicitly indicate the quantity of indicated technical characteristic.Define as a result, " first ",
The feature of " second " can explicitly or implicitly include at least one of the features.In addition, the technical side between each embodiment
