As shown in Figures 1-2, the rocker assembly for a circuit breaker of the utility model includes a rocker body, one end of the rocker body is used to be rotatably connected to one end of a connecting rod 1, the other end of the connecting rod 1 is used to be rotatably connected to the control end of the opening and closing mechanism in the circuit breaker, and the other end of the rocker body is used to be rotatably connected to an operating handle; the rocker body includes a first rocker 2, a second rocker 3 and an adjusting member 4, the two ends of the adjusting member 4 are respectively adjustably connected to one end of the first rocker 2 and one end of the second rocker 3, the adjusting member 4 is used to adjust the distance between the first rocker 2 and the second rocker 3 to adjust the length of the rocker body, the other end of the first rocker 2 is used to be rotatably connected to the operating handle, and the other end of the second rocker 3 is used to be rotatably connected to one end of the connecting rod 1.

The first screw rod 41 and the second screw rod 42 are respectively provided at both ends of the adjusting member 4, and the first screw rod 41 and the second screw rod 42 are coaxially arranged. The first rocker arm 2 is provided with a first threaded hole 21 at one end, and the first screw rod 41 is threadedly connected to the first threaded hole 21. The second rocker arm 3 is provided with a second threaded hole 31 at one end, and the second screw rod 42 is threadedly connected to the second threaded hole 31. The direction in which the second screw 42 and the second threaded hole are threadedly connected is opposite to the direction in which the first screw 41 and the first threaded hole 21 are threadedly connected. After adopting this structure, since the direction in which the second screw and the second threaded hole are threadedly connected is opposite to the direction in which the first screw and the first threaded hole are threadedly connected, when the adjusting member is rotated, under the cooperation of the first screw and the first threaded hole, and under the cooperation of the second screw and the second threaded hole, the first rocker arm and the second rocker arm can be moved away from or close to each other, so that the overall length of the rocker arm body can be adjusted, that is, when the adjusting member is rotated to one side, the length of the rocker arm body can be shortened, and when the adjusting member is rotated to the other side, the length of the rocker arm body can be lengthened.

A regular hexagonal annular protrusion 43 is provided in the middle of the adjusting member 4, and the annular protrusion 43 is used to be inserted into a wrench to facilitate the wrench to rotate the adjusting member 4; by providing a regular hexagonal annular protrusion in the middle of the adjusting member, when the adjusting member needs to be rotated, the wrench can be inserted into the annular protrusion and the adjusting member can be rotated by the wrench, so that the adjusting member can be easily rotated, that is, the overall length of the rocker body can be easily adjusted.
