Fig. 2 is circuit breaker transmission device partial structural diagram of the present invention.
In figure：1st, box of the circuit breaker shell 2, drive rod 3, pin III 4, pin II 5, connecting lever component 6, support 7, pin I 8, tune
Whole silk 9, insulated tension pole component 10, curved connecting plate 11, bearing pin 12, direct-connected plate.
Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, and described is to the present invention
Explain rather than limit.
As depicted in figs. 1 and 2, breaker includes transmission device, transmission device to a kind of embodiment of breaker in the present invention
Including circuit breaker case 1, the support 6 welded together with circuit breaker case 1, originally preferably in case as depicted in figs. 1 and 2, branch
The top of frame 6 is provided with the circular port with the input that is used as power, and its bottom is provided with the chute as power output, and top circular port
Linked together by pin shaft II 4 and connecting lever component 5, the upper end of connecting lever component 5 is connected by pin III with drive rod, and its lower end passes through
Pin I 7 is connected with adjustment silk 8, and pin I 7 is as in the chute of the bottom of support 6；Pass through between adjustment silk 8 and insulated tension pole component 9
It is threaded togather；The connecting lever component 5 includes two curved 10, bearing pins, 11, two direct-connected plates 12 of winning in succession, and three sets
Put meet it is claimed below：Curved connecting plate 10 is linked together with direct-connected plate 12 by bearing pin 11, and two curved connecting plates 10 are as upper end
And with one heart, two direct-connected plates 12 can freely rotate as lower end and concentric, curved connecting plate 10 with direct-connected plate 12 along bearing pin 11.
In practical operation in use, when driving input power to drive the level of drive rod 2 to left movement, the upper end of connecting lever component 5
