The inner side of the second rotating disk 201c is threadedly engaged with the outer wall of the second telescopic rod 201b. When the second rotating disk 201c is rotated, the second telescopic rod 201b is raised or lowered accordingly.

[0040] Furthermore, the second supporting assembly 200 includes four second supporting members 201, which are arranged in groups of two and are respectively arranged on both sides of the middle first supporting member 101, and the two sides are used to place the pillar porcelain bottle porcelain sleeve and the arc extinguishing chamber porcelain sleeve respectively.

[0041] The placement block 202 is fixedly arranged on the upper side of the second telescopic rod 201b. The placement block 202 is in the shape of a semicircular ring with an upward opening and cooperates with the support porcelain bottle porcelain sleeve and the arc extinguishing chamber porcelain sleeve.

[0042] When in use, place the circuit breaker pole in the clamping plate 102a and the placement block 202, rotate the first rotating disk 101b and the second rotating disk 201c, and adjust the height of the first telescopic rod 101c and the second telescopic rod 201b so that the hole on the pole matches the hole on the clamping plate 102a and the placement block 202. The circuit breaker pole is clamped and fixed, and the connecting bolts between the crank arm box, the support porcelain bottle, the moving contact, the arc extinguishing porcelain bottle, and the static contact are unscrewed. The five parts can be disassembled, and the support porcelain bottle porcelain sleeve and the arc extinguishing porcelain bottle porcelain sleeve are removed from the pole. The second support assembly 200 is moved away, and the internal structure can be inspected and repaired. The internal structure of the circuit breaker can also be directly observed and the movement of the internal parts can be intuitively seen, so that students can understand the working principle of the circuit breaker more intuitively.
