The transmission of gag lever post 12, first gag lever post 15 is spacing to the first isolation rotatable lamella 3, output drive plate 7 respectively, mechanism is in isolation
Conjunction state；Isolation isloation state is to rotate counterclockwise the isolated operation axle 10 of the state of isolation conjunction by operation handle, energy storage bullet
Spring 1 slowly compresses, and rear mistake " dead point " drives the second isolation rotatable lamella 5, actuating sleeve 21, transmission by isolating rotatable lamella connecting shaft 19
Card wheel 6 is overall to be rotated counterclockwise, and because the thumb wheel 34 on output drive plate 7 is stuck in the neck of transmission card wheel 6, therefore it is driven card
Wheel 6, which rotates counterclockwise, drives output shaft 9, output drive plate 7, shaft insulation 28, moving contact piece 27 this entirety to rotate clockwise, and arrives
Up to isolation point position when because effect of inertia, trend that the oriented grounding static contact 26 of moving contact piece 27 moves, just because of left side
Limiting bracket 22 top withstand output drive plate 7 rotate clockwise, mechanism is rested on isolation isloation state.
3rd, conjunction state is grounded to ground connection isloation state, refers to Figure 17 to Figure 23.Ground connection conjunction state is maintained by the 3rd
The transmission of support limit bar 14, second gag lever post 16 is spacing to the first ground connection rotatable lamella 2, output drive plate 7 respectively, is in mechanism
Ground state；Ground connection isloation state is to rotate 8 hour hands clockwise of ground connection operating shaft of the state of ground connection conjunction by operation handle, storage
Energy spring 1 slowly compresses, and rear mistake " dead point " passes through spring pedestal fixed block 20 and drives the second ground connection rotatable lamella 4, the and of actuating sleeve 21
Transmission card wheel 6 is overall to be rotated clockwise, and because the thumb wheel 34 on output drive plate 7 is stuck in the neck of transmission card wheel 6, therefore pass
Move card wheel 6 and rotate clockwise this overall counterclockwise turn of drive output shaft 9, output drive plate 7, shaft insulation 28 and moving contact piece 27
It is dynamic, when reaching the position of ground connection point because effect of inertia, trend that the oriented isolation static contact 25 of moving contact piece 27 moves, it is positive because
For the limiting bracket 22 on right side top withstand output drive plate 7 rotate counterclockwise, mechanism is rested on ground connection isloation state.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
