When the first housing 21 and the second housing 22 are for closing entire state, because the recess 1132 of the first cam part 113 of projection 1331 pairs of cylinder 11 sides of its second cam part 133 of cam member 13 does chimeric, allow the second housing 22 keep and lock and entire state is closed to the first housing 21, therefore the locking means not needing other other.

When relative for second housing 22 first housing 21 is opened by self-closing entire state gradually, flange component 124 and hinge-rod 12 will do a little rotation, the protuberance 1331 of its second cam part 133 of cam member 13 of together rotating with hinge-rod 12 can from cylinder 11 bottom it on 112 internal surfaces the recess 1132 of the first cam part 113 depart from, climb (being equivalent to the slip between the first cam part 113 its rake 1133 and its rake 1333 of the second cam part 133) toward protuberance 1131, now cam member 13 112 sequentially to depart from (with reference to Fig. 6) bottom it from cylinder 11 because of the elastic force of opposing elastic mean 14 its saucerspring 14a ~ 14e.In this case to more open the second housing 22 again, need use the surface friction drag (forming friction torque afterwards) between the first cam part 113 its rake 1133 and its rake 1333 of the second cam part 133 and friction pads 15 that crimp than elastic mean 14 and cylinder 11 bottom it outside 112 between the larger strength of surface friction drag.Again, if decontroled by the second housing 22 in this case, under the elastic force of its saucerspring of elastic mean 14 14a ~ 14e, the second housing 22 will return back to and close entire state.

Second housing 22 is opened into required angle, when the protuberance 1331 of the second cam part 133 contacts with the protuberance 1331 of the first cam part 113, frictional force is produced under the flat of the upper surface of both two protuberances 1331,1331 temporarily contacts and slides, by the frictional force of this frictional force and friction pads 15, even if let go in unlatching way, the second housing 22 still can be allowed to maintain arbitrarily angled unlatching to the first housing 21 and static maintenance.

When again the second housing 22 being opened into larger angle, under the state of opening completely, the protuberance 1331 of its second cam part 133 of cam member 13 can arrive at the nested position of its next recess 1132 of the first cam part 113, again by the restoring force of the saucerspring 14a ~ 14e of elastic mean 14, protuberance 1331 is embedded in recess 1132 automatically via absorption function, allows the second housing 22 be locked to opening state.In the present embodiment, this opening angle is 180 degree.

When closed the second housing 22 opened completely, via sequence of operation contrary to the above, be namely returned to and initial close entire state.Even form the momentary status before closing entire form in addition, because the protuberance 1331 of the second cam part 133 is the recess 1132 automatically embedding the first cam part 113 by the restoring force of the saucerspring 14a ~ 14e of elastic mean 14, therefore still there is absorption action when closing entire operation.
