When rotation is required, the buckle corresponding to the second fixed shaft 506 of the connecting rod 507 is released and rotated away from the corresponding second pressure plate 502. Then the connected GCB arc-extinguishing chamber can be flipped over. The operation is simple and easy to use.

[0033] The lower sleeve 503 is topped with an upper sleeve 504. The lower sleeve 503 and the upper sleeve 504 are combined to form a circular space.
