Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, an instantaneous mechanism for a circuit breaker includes a lower iron core 1, the surface of the lower iron core 1 is rotatably connected with an upper armature 2 through a bearing, the upper armature 2 and the lower iron core 1 are both in a U shape, the surface of the lower iron core 1 is fixedly connected with a fixed frame 3, the surface of the upper armature is fixedly connected with a contact plate 4, and the surface of the upper armature 2 close to the fixed frame 3 is in contact with the surface of the fixed frame 3 far away from the lower iron core 1.

Through-hole 5, two through-hole 5 is linked together all seted up on the surface of fixed frame 3 and lower iron core 1 for the adapting unit that pegs graft gives whole day dress preliminary location.
