The drive sleeve (6) is axially moveable, and moving direction is towards operation handle (4), at this time since top cap slot (3.2) and shell are convex
(10.1) cooperation is played, so top cap (3) will not be rotated together with drive sleeve (6)；
Automatic closing and closing by hand double mode:
When having a power failure suddenly in above-mentioned automatic closing process, or causing motor to stop operating suddenly due to fortuitous event,
It rotates about 90 ° of top cap (3) counterclockwise with straight screwdriver at this time, can not only carry out closing by hand under such state but also can be into
Row automatic closing；
Manual brake separating process:
After in-place closing, due to the elastic force of spring, drive sleeve (6) is mobile to the direction far from operation handle (4), and then makes a left side
End tooth (6.2.1) and handle teeth (4.1) separation；After left end tooth (6.2.1) and handle teeth (4.1) separate, manual operation operation
It is turned to sub-gate position by closing position, is achieved in manual brake separating by handle (4)；
Automatic brake separating process:
When miniature circuit breaker is in "on" position, when receiving sub-gate signal, miniature circuit breaker presses following procedure automatic brake separating:
Sub-gate signal is sent to motor (1), rotates motor (1)；Motor (1) rotation drives worm screw (2) rotation, and worm screw (2) turns
It is dynamic to drive worm gear (5) rotation；Worm gear (5) rotation drives drive sleeve (6) rotation；At this point, operation handle is in closing position, work as biography
When dynamic set (6) rotation, moving tooth (6.4) rotation for being fixed on drive sleeve is driven, moving tooth (6.4) will push driving lever and turn around axis when rotating
Dynamic, the other end of driving lever, which touches contact, to be made to switch separating brake, and the moving tooth (6.4) Yu driving lever of drive sleeve are in contact condition at this time,
Under this state, handle cannot realize closing by hand, and when motor rotates again, the moving tooth (6.4) of drive sleeve is separated with driving lever,
It is now in "on" position, can not only automatic brake separating have been carried out under such state but also manual brake separating can be carried out；It at this time simultaneously can be with
Meet automatic switching on and off condition.
