Position；Mechanism output shaft 3 is broken due to the active force without permanent magnet mechanism push rod 21, the balance of power, continues to turn along counterclockwise
It is dynamic until separating brake in place, realize manual brake separating.
According to electric switch-on, electronic separating brake and manual brake separating process, closing by hand procedure is specific as follows：Carry out
Closing by hand is operated, and only need to up and down reciprocatingly pull hand sympodium 12, and closing connecting lever 27 by the hand on hand sympodium 12 promotes mounted in main shaft
Transmission crank arm 28 on 11, and then main shaft 11 is rotated in the clockwise direction, stretching combined floodgate spring 8 while main shaft 11 is rotated.
When combined floodgate spring 8 is stretched to certain position（Cross middle position）, combined floodgate spring resets rapidly, releases energy, and is mounted in main shaft during this
Also rapid edge is rotated clockwise cam 25 on 11；Meanwhile, cam 25 promotes rapidly permanent magnet mechanism push rod 21 to left movement, and leads to
Cross permanent magnet mechanism push rod 21 and promote output shaft 3 along rotating clockwise certain angle, and then switch is closed a floodgate, mechanism combined floodgate spring 8
And main shaft 11 rotates back into initial position, closing by hand action is completed.
