Fig. 1 is axonometric chart when turning arm launches in this utility model；
Fig. 2 is axonometric chart when turning arm is folded in this utility model；
Fig. 3 is explosive view of the present utility model.
Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.This utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the anti-diastema folding device of a kind of aircraft, including two parallel fixed plates 101, are fixed on
Fix bar 102 between two fixed plates 101, gag lever post 105, compression spring 103 and turning arm 201；Fixed plate 101 is grown along it
Degree direction is provided with chute 107, chute 107 and is provided with the slide bar 104 slided along chute 107, and one end of gag lever post 105 is through fixation
Bar 102 and it is slidably connected with fix bar 102, the other end is fixedly connected with slide bar 104, and compression spring 103 is located on gag lever post 105
It is outer and be sandwiched between fix bar 102 and slide bar 104；One end of turning arm 201 is fixedly connected with horn, and it is flat that the other end is extended with two
Capable swivel plate 202, swivel plate 202 is rotatably connected with fixed plate 101, and swivel plate 202 is provided with and slide bar away from the side of horn
104 arc notch 203 for abutting；When slide bar 104 shifts to fix bar 102, slide bar 104 departs from arc notch 203, now revolves
Pivoted arm 201 rotates along rotating shaft 106, when slide bar 104 is shifted to arc notch 203 and is contacted with arc notch 203, arc notch
