The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model constitutes and to consist essentially of a pair of corresponding member, and this two member comprises that respectively a pedestal 10,10 ', one controll block 20,20 ', a positioning block 30,30 ', two springs 40,40 ' and adjust screw 50,50 ' etc.

Pedestal 10,10 ' comprises on a middle body and two flanks, 101,101 ', two flanks 101,101 ' respectively establishes locating hole 102,102 '; Middle body comprises a box body 103,103 ', and both walls 104,105,104 ', 105 ', a tip hole 106,106 ' and pin 107,107 ' are in both walls 104,105,104 ', 105 ' the inboard corresponding chute 108,108 ' that is provided with.

Controll block 20,20 ' is a L type blocks, which is provided with 201,201 ', second tip hole, first tip hole, 202,202 ' a pair of protruding tip 203,203 ' and first groove, 204,204 ', second groove 205,205 '.

Locating piece 30,30 ' has 301,301 ', two positioning convex rods 302,302 ' of a projection for being located at the member in the box body 103,103 '; Locating piece 30,30 ' is arranged in the box body 103,103 '.

Two springs 40,40 ' are in order to be placed on the nose bar 302,302 '.

Adjust screw 50,50 ' and be fixed in pedestal 10,10 ' downside, have two screws 501 ', in order to withstanding on spring 40,40 ' below, to adjust spring 40,40 ' elasticity.

Controll block 20, the protruding tip 203,203 ' of 20 ' mat are arranged on the chute 108,108 ', and mat pin 107 ', 107 is arranged on relative pedestal 10 ', 10 box body 103 ', 103 top positions; Between relative two controll blocks 20,20 ' second tip hole 202,202 ', locate mutually with a pin 80.

On the flank 101,101 ' of two pedestals 10,10 ' opposite face screw 70,70 ' is set, mat screw 70,70 ' precession or back-out can be controlled the smooth of relative slot between two pedestals 10,10 '.

Mat spring 40, an end of 40 ' are butted on to be adjusted on the screw 50,50 ', under nose bar 302,302 ' location, locating piece 30,30 ' protruding rail 301,301 ' are butted on first groove 204,204 ' or second groove 205,205 ', make the pedestal 10,10 ' of two phase doublings moving (change angle) be stable state under this two groove 204,204 ', 205, the 205 ' angle that is provided.

As Fig. 4, Figure 5 shows that mat screw 91 by locating hole 102,102 ' with the flat state of the utility model constructional device when plate body 90,90 ' is gone up, Fig. 6 then is the state of 180 ° of turnovers; When being flat state, it is minimum that the combination between plate body 90,90 ' is the gap, and external surface be can't see the state of hinge.
