The utility model describes the vibration linkage structure, and how to realize opening and closing of the switch by rotating the opening half shaft 1 is not described in detail here;

[0030] The interlock conversion paddle 3 is arranged above the opening trip springboard 2, and is provided with a second torsion spring 5 to provide a reset force. The interlock conversion paddle 3 and the opening trip springboard 2 can drive each other to rotate to achieve opening and closing; the interlock conversion paddle 3 is connected to the fuse tripping device to achieve interlocking with the fuse tripping device.
