Embodiment Construction
[0013] like figure 1 , figure 2 , image 3 As shown, an embodiment of a circuit breaker operating mechanism, the circuit breaker operating mechanism in this embodiment includes a mechanism chassis 10, on which the mechanism chassis 10 is rotatably equipped with a body crank arm 1, on which the mechanism chassis 10 is fixed A support 6 is installed, and a mechanism output shaft 7 is rotated on the support 6. The output shaft 7 of the mechanism is driven by the output crank arm 3 detachably installed on the support 6. The body crank arm 1 passes through the axial length The adjustable connecting rod 2 is in transmission connection with the output crank arm 3. The main body crank arm 1 forms a planar four-bar linkage mechanism through the axially adjustable connecting rod 2 and the output crank arm 3. The connecting rod 2 here consists of two axial The two ends of the connecting rod body 21 are respectively provided with connecting rod bodies 21 with opposite external threads,...
