[0002] High-voltage circuit breakers play a controlling role in high-voltage circuits and are one of the important electrical components in high-voltage circuits. High-voltage circuit breakers are special electrical appliances that connect or disconnect high-voltage circuits under normal or fault conditions. The breaking capacity of high-voltage circuit breakers can be made very high during the manufacturing process.

The main structure of high-voltage circuit breakers is roughly divided into the current guide part, arc extinguishing part, insulation part, and operating mechanism part.

However, the distances between the four threaded holes at the four corners of the bottom of high-voltage circuit breakers of different specifications are different, so the base cannot adapt to high-voltage circuit breakers of different specifications.

[0023] In order to fix the circuit breaker body 2 on the mounting block 7, the four corners of the bottom surface of the circuit breaker body 2 are respectively fitted with the top surfaces of the four mounting blocks 7, and the four corners of the bottom of the circuit breaker body 2 are threadedly connected with fastening bolts 16, and the lower ends of the four fastening bolts 16 are respectively threadedly connected in the adjacent threaded holes 8.

[0024] In order to enable the second bidirectional screw 5 to drive the adjacent connecting plate 10 to move when the front and rear sides move, the left and right sides of the facing surfaces of the two connecting plates 10 are fixedly connected with fixing plates 17, and the front and rear fixing plates 17 are movably sleeved on the surfaces of the adjacent second bidirectional screw 5 respectively.

When adjusting the distance between the left and right mounting blocks 7, the distance between the left and right mounting blocks 7 after adjustment can be determined by observing the scale on the second scale 24 corresponding to the movement of the second pointer 25, thereby facilitating the adjustment of the four mounting blocks 7 to a suitable distance, without the need to use a ruler to measure repeatedly each time, which is more convenient to use.
