The structure in receiving space that plate and two positioning cams are surrounded is：The position limiting structure includes a cylindric first boss
601 and a strip stopper slot 602, the first boss is fixedly arranged on the limited block towards the side of second connecting plate, institute
State the middle part that stopper slot is fixedly arranged on side of second connecting plate towards the first boss, the length direction of the stopper slot
Line direction with two positioning cams is consistent, the first boss along the stopper slot width stop, along the limit
Slide and be placed in the stopper slot in position slot length direction.So, by the cooperation of boss and stopper slot, limited block can be determined
Position is in the receiving space that two positioning cams, the first connecting plate and the second connecting plate are surrounded.Limited block plays important control
The effect of double axis of rotation, stopper slot provides zone of action and spacing for cylindric limited block.
Preferably, the spacing trench bottom forms an ellipticity spacing hole 603, the long axis direction of the spacing hole and two
The line direction of the positioning cam is consistent, and the first boss passes through the stopper slot, and along the short axle side of the spacing hole
To stop, along the long axis direction slip cap of the spacing hole in the spacing hole.So, matching somebody with somebody by spacing hole and boss
Close, further limited block can be carried out spacing, play more preferable position-limiting action.
Preferably, the ultimate range that the first boss is slided in the spacing hole is equal to the limited block in two institutes
State the ultimate range slided between breach.In such manner, it is possible to further be carried out to limited block spacing, more preferable position-limiting action is played.
Preferably, the position limiting structure is also included by first connecting plate middle part both sides towards the positioning cam bending
The two relative catch 604 for being formed, the positioning cam backstop is between two catch.So, by two catch
Further limited block can be carried out spacing, play more preferable position-limiting action.
Preferably, each shaft core is corresponded to, a closing cam 70 is provided with, the closing cam is positioned at second connection
Side from backboard to the positioning cam, each closing cam with respect to shaft core can circumferential stop axially slidably, it is described to close
Close cam and the relative face of second connecting plate is provided with the first raised 701 and second groove 301 that size matches, it is described
First projection can circumferentially slide in and out first groove.During specific implementation, can be convex towards closure in the second connecting plate
First groove is set on the one side of wheel, it is recessed with first towards setting size on the face of the side of the second connecting plate in closing cam
The projection that groove matches, by the mutual cooperation of raised and the first groove, realizes automatic closing function of the product in set angle；
Preferably, two shaft cores have been respectively fixedly connected with support 80 near one end of first connecting plate, for being embedded in
Need in the part and matrix that rotate, if two shaft cores near one end of the closing cams be arranged with successively pad 90 and
Dry butterfly shell fragment 100, first connecting plate, positioning cam, the second connecting plate, closing cam, butterfly shell fragment and pad lead to
The locking positioning of nut 110 is crossed in two shaft cores, for realizing the function that close-fitting is positioned.
Preferably, noise reduction pad 120, the closing cam direction are provided between the closing cam and the butterfly shell fragment
