Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] Such as Figure 1 to Figure 5 As shown, the opening and closing holding mechanism of the circuit breaker includes a driving shaft 2, a sliding rod sleeve 5 connected with the driving shaft 2, and a central shaft 7 of a rotating pair formed by cooperating with the sliding rod sleeve 5. The rod shaft 6 constitutes a first sliding pair, and a spring 8 is sleeved on the rod shaft 6 .
[0024] Bracket 9, cooperating with bracket 9 to install shaft two 11 forming the second sliding pair, bracket 9 connects slide bar shaft 6 through column pin one 12, column pin one 12 cooperates with strip-shaped hole three 9-2 offered on the bracket 9 to form The third sliding pair.
[0025] The moving contact 14 installed on the bracket 9 , the static contact 15 cooperating with the moving contact 14 , and the limit gear 10 cooperating with the bracket 9 for limiting the distance ...
