Switch knob, combined floodgate connecting lever by connecting plate connect keep connecting lever, keep connecting lever be fixed in rotary shaft, the both ends of rotary shaft with
Support unit is connected, and keeps being provided with holding connecting lever back-moving spring between connecting lever and rotary shaft；The output unit includes solid
The output toggle arm of roller is provided with due to the output shaft on support unit and surface, roller is engaged with the projection of cam.
Preferably, the support unit includes left plate, right plate and the support shaft being fixedly connected with both, hanging spring shaft,
One end of energy-stored spring is connected with hanging spring shaft, the other end and energy storage axis connection；Output shaft is connected by bearing with two blocks of side plates；Turn
The both ends of moving axis are connected with left plate, right plate respectively.
Compared with prior art, the utility model has the advantages that：
1. the utility model need not be electronic, the mode of manual energy storage, closing by hand can be fully relied on, in permanent magnetism open circuit
Device dead electricity overlong time can not electric switch-on when, complete manual energy storage, close a floodgate, ensure primary circuit power transmission；
2. by being closed a floodgate again after then passing through spring energy-storage, fully achieve with permanent-magnet electric close a floodgate similar in closing speed
And the time；
3. the utility model is in itself without the functions such as holding, sub-switching operation of closing a floodgate, the combined floodgate holding of breaker, sub-switching operation
Still reached by permanent magnet mechanism, this makes the utility model there was only less than half volume of conventional springs operating mechanism, and can
With with permanent magnet mechanism perfect cooperation, it is its small volume, simple in construction, convenient for installation and maintenance, cheap.
