[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The current transformer mounting base can move relative to the base and the copper rod mounting base can be raised and lowered relative to the base, thereby enabling the position adjustment of both the current transformer mounting base and the copper rod mounting base to accommodate different current transformer bodies and copper rod bodies. Then, clamping is performed by clamping arms, realizing universality for different current transformer bodies and copper rod bodies, reducing manufacturing costs and reducing additional placement space.

[0021] 2. The first base plate and the second base plate are used together to support the transformer body. The first base plate and the second base plate can be brought close to each other to adjust the distance between the first longitudinal positioning block and the second longitudinal positioning block, thereby adapting to transformer bodies of different lengths.

[0022] 3. When the first base plate and the second base plate are close to each other, the first comb tooth can be inserted into the second comb groove and the second comb tooth can be inserted into the first comb groove, thus ensuring that the first base plate and the second base plate always support the transformer body.

[0023] 4. The two lateral positioning blocks can move closer or further apart to adjust their spacing, thus adapting to transformer bodies of different widths.

[0024] 5. The mounting block can be connected to the first threaded part of the first adjusting rod through the first threaded hole. When the first adjusting rod rotates, it drives the mounting block to rise and fall relative to the base, thereby adapting to the docking positions of the current transformer body and the copper rod body at different heights.

[0025] 6. The second threaded part of the second adjusting rod is sequentially threaded to the second threaded hole of a nut and passes through the clamping arm and is threaded to the second threaded hole of another nut. When the second adjusting rod rotates, it rises and falls relative to the clamping arm, thereby driving the current transformer clamping block to rise and fall relative to the clamping arm, thus adapting to the current transformer body of different heights.

[0026] 7. The copper rod clamping block can be connected to the third threaded part of the third adjusting rod through the third threaded hole. When the third adjusting rod rotates, it drives the copper rod clamping block to rise and fall relative to the clamping arm, thereby adapting to copper rod bodies of different heights.
