The restrained condition of corresponding micro-disconnected W dropout button trip positions it is pushed on pin 7-1.So, when driving circle hypodontia wheel 3 driving manual control circle to lack
When gear 2 is disengaged from after going to corresponding control handle W-1 open position, at the limit convex 9-1 on curved bar control position cam 9
In curved bar 7 end pin 7-1 being pushed into the constrained of the corresponding micro-disconnected dropout in arcuate groove upper end, therefore, micro-disconnected on dropout button drive
The trip shaft of micro-disconnected inside is also maintained at trip positions because curved bar 7 is restrained, time no longer as originally not having distribution to grasp micro-disconnected that
Sample, after working as manual combined floodgate, trip shaft necessarily enters snapped-in position, even if result makes now to carry out manual closing operation, also will
Control handle is made necessarily to return open position under the effect of micro-disconnected internal reset spring immediately owing to being snapped, i.e. hands
When pushing away micro-disconnected control handle to closing position, it is impossible to making control handle be maintained at closing position because of buckle, once external force is cancelled, hands
Handle can automatically return to open position, it is achieved that does not allow the function of micro-disconnected closing by hand after electronic separating brake.And when motor 6 orders about
Dynamic circle hypodontia wheel 3 engages with manual control circle hypodontia wheel 2 when going to closing position, due to spacing during cam 9 concomitant rotation of curved bar control position
Protruding 9-1 quickly departs from the constraint to curved bar 7, and recovery original function is entered buckle by trip positions by the most micro-disconnected trip shaft
Position, thus ensure reliable electric switch-on, therefore the ingenious cooperation of the present embodiment circle hypodontia wheel and curved bar control position cam ensures
After electronic separating brake while not allowing micro-disconnected closing by hand, but can be with electric switch-on.
