Left feather key and right feather key in mandrel are located in female hinge in the keyway of left and right sleeve, and the middle feather key in mandrel will be disengaged from son
The keyway of hinge upper bush and enter in power bin and compressed spring.Around central axis subpage piece and release button, group hinge
In another keyway when being aligned with the keyway in female hinge, the spring in power bin can push mandrel to the right by middle feather key
Mobile and until in the keyway that middle feather key enters subpage on piece, feather key and keyway can cooperate mandrel to lock son jointly at this time
Hinge and female hinge.
When dismantling or assemble subpage piece and female hinge, removes button and push mandrel to the left, right side and mother when mandrel
When the right side of hinge upper bush is concordant, the left feather key in mandrel will remove the keyway of left sleeve in female hinge to the left.When from the heart
When removing left feather key on axis, mandrel, middle feather key and right feather key can be taken out along the sleeve and keyway on subpage piece and female hinge
Out.It is finally separating subpage piece and female hinge can be taken off spring in power bin.
The utility model has the beneficial effects that being carried out by primary and secondary hinge of the built-in limit self mechanism to hinge automatic
Limitation locking.

Specific embodiment
In Fig. 1, Fig. 2, Fig. 4, Fig. 5, Fig. 8, Fig. 9, Tu10Zhong, subpage piece 3 and female hinge 4 are Rectangular Plate Structure, subpage
Piece 3 is longitudinally disposed with female hinge 4 and forward laps, and is connected separately with the set of left and right two in the left and right ends of female 4 lower edge of hinge
Cylinder, is connected with a sleeve in the middle position of 3 lower edge of subpage piece.A left side of the sleeve connection in female hinge 4 on subpage piece 3
Between right sleeve and it is coaxially disposed.Keyway 5 is offered on the hole wall of female 4 or so sleeve of hinge, in the hole of 3 sleeve of subpage piece
If offering arterial highway keyway 5 corresponding with the keyway 5 in female hinge 4 on wall, the keyway 5 is parallel with the axis of sleeve.
The right end hole of left sleeve is set as power bin 7 in female hinge 4, and the left end hole of 3 upper bush of subpage piece is set as power bin 7, power
