Small-sized circuit breaker operation mechanism

Disclosed is a small-sized circuit breaker operation mechanism. The small-sized circuit breaker operation mechanism comprises a shell (1); a circuit breaker handle (2) is mounted in a shell mounting groove (101); a shaft rod part (301) of a linkage rotary shaft (3) is mounted in a mounting axial hole (102) of the shell (1); the circuit breaker handle (2) is arranged on a rotary shaft part (302) of the linkage rotary shaft (3) in a sleeving manner; and the linkage rotary shaft (3) is connected with a movable contact mechanism (5) through a connecting rod (4). When the circuit breaker handle stops at any position, the circuit breaker handle can be manually operated to be switched on or switched off to enable the circuit breaker to be in the switched-on or switched-off position clearly, so that the on-off safety of the circuit breaker can be improved. 种小型断路器操作机构，它包括外壳(1)，断路器手柄(2)装在外壳安装槽(101)内，联动转轴(3)的轴杆部(301)装在外壳(1)的安装轴孔(102)中，断路器手柄(2)套装在联动转轴(3)的转轴部(302)，联动转轴(3)通过连杆(4)与动触头机构(5)连接，本发明使断路器手柄停在任意位置时，可手动操作断路器手柄进行闭合或
