Extension spring 1a holds operation rotating shaft 100 also by the driving lever 13, as shown in figure 13, further to lock the reversing plate 3 and institute
State operation rotating shaft 100.
Now, as needed separating brake again, as shown in Figure 12, Fig. 5, give the power transmission again of solenoid 5, solenoid 5 it is electric when suck
Dynamic iron core 7, dynamic iron core 7 drive the drive pin 10 to move along another described guiding hypotenuse 33 of reversing plate 3 by STATEMENT OF FEDERALLY SPONSORED 9
Then reversing plate 3 is driven to rotate counterclockwise, operating shaft 100 is and then rotated counterclockwise, and first connecting rod 24 is connected in operating shaft 100
On, such as from terms of 2 side of contact mechanism, first connecting rod 24 to rotate clockwise, therefore first connecting rod 24 just by the second bearing pin 27,
Second connecting rod 25, the 3rd bearing pin 28 drives gland 29 and disconnecting link 23 to rotate counterclockwise along the first bearing pin 26, and disconnecting link 23 drives dynamic touching
21 depart from static contacts 22, realize separating brake.Now operate rotating shaft 100 that other driving lever 13 can be driven to touch other microswitch 12 to touch
Point makes 5 power-off of solenoid, after 5 power-off of solenoid, as shown in figure 3, reseting pressuring spring 6 drives dynamic iron core 7 to reset, described first
Extension spring 11 drives the drive pin 10 to coordinate on another locating slot 34 of reversing plate 3 to position the reversing plate 3 and described
Operation rotating shaft 100；Second extension spring 1a holds operation rotating shaft 100 also by the driving lever 13 simultaneously, further to lock described changing
To plate 3 and the operation rotating shaft 100.
The above is only a preferred embodiment of the invention, the change that those skilled in the art is made to be equal to by claim
Both fall within the protection domain of this case.
