One end of the connecting rod 7 is fixedly connected to the bottom of the mounting plate 2, and the connecting rod 7 extends to the bottom of the mounting shell 1 and is fixedly connected to the push plate 9. The outer wall of the push plate 9 is movably connected to the fixed shell 8, and the top of the fixed shell 8 is fixedly connected to the bottom of the mounting shell 1. The bottom of the push plate 9 is fitted with an elliptical rotating wheel 19, and both sides of the outer wall of the elliptical rotating wheel 19 are fixedly connected to the rotating rod 20, and the outer walls of the ends of the two rotating rods 20 that are away from each other are rotatably connected to the inner wall of the fixed shell 8 through a bearing;
[0023] In the specific implementation process, it is worth pointing out that, under the cooperation of the connecting rod 7, the push plate 9 and the elliptical rotating wheel 19, the rotating rod 20 is used to drive the elliptical rotating wheel 19 to rotate, so that the push plate 9 is pressed, so that the push plate 9 drives the connecting rod 7 to move, so that the clamping plate 3 is moved out of the inside of the mounting shell 1, and the clamping plate 3 is opened under the action of the torsion spring 21, so that it can clamp the mutual inductor, and the mutual inductor is connected to the connecting line 11 through the wiring terminal 5, so as to calibrate it;
[0024] Furthermore, the two terminals 5 are connected to each other on one side thereof, and the connecting wire 11 is extended to the lower side of the connecting rod 7 and fixedly connected to the inner wall of the fixed shell 8, and the connecting wire 11 is extended to the outer wall of the fixed shell 8 and a connecting socket 14 is installed;
[0025] In the specific implementation process, it is worth pointing out that, with the cooperation of the connecting wire 11, the connecting rod 7 and the wiring socket 14, the detection device is inserted into the wiring socket 14, and after the transformer is clamped, the transformer is calibrated through the cooperation of the wiring terminal 5;
[0026] Furthermore, limit wheels 6 are installed on both sides of the inner wall of the installation shell 1, and the outer wall of the limit wheel 6 is attached to the outer wall of the clamping plate 3. The bottom of the fixed shell 8 is fixedly connected with a handle 13;

[0028] Specifically, when using the clamping assembly for transformer calibration, hold the handle 13, extend the clamping assembly toward the transformer, and open the clamping plate 3 at an appropriate distance from the transformer, use the rotating rod 20 to drive the elliptical rotating wheel 19 to rotate, squeeze the push plate 9, so that the push plate 9 drives the connecting rod 7 to rise and fall, so that the mounting plate 2 drives the clamping plate 3 to move out of the mounting shell 1, and when the clamping plate 3 is moved out, the clamping plate 3 will be opened close to the limiting wheel 6 under the action of the torsion spring 21, thereby clamping the transformer and connecting it to the terminal 5, and the detection device is inserted into the wiring socket 14, so that the transformer is calibrated through the connecting line 11.
[0029] Embodiment 2: By Figure 1-4 It can be seen that the bottom of the fixed shell 8 is fixedly connected with a servo motor 12, the output end of the servo motor 12 extends to the inside of the fixed shell 8 and is fixedly connected with a driving rod 15, the outer wall of the driving rod 15 is fixedly connected with a driving gear 16, the outer wall of the driving gear 16 is meshedly connected with a driven gear 17, and the outer wall of the driven gear 17 is fixedly connected to the outer wall of the rotating rod 20, wherein the model of the servo motor 12 is not limited;
[0030] In the specific implementation process, it is worth pointing out that, under the cooperation of the servo motor 12, the driving rod 15 and the driving gear 16, the servo motor 12 is used to drive the driving rod 15 to rotate, thereby driving the elliptical rotating wheel 19 to rotate through the meshing of the driving gear 16 and the driven gear 17, thereby pushing the push plate 9;
[0031] Furthermore, a spring 10 is fixedly connected to the top of the push plate 9, the top of the spring 10 is fixedly connected to the top of the inner wall of the fixed shell 8, the inner wall of the spring 10 is sleeved on the outer wall of the connecting rod 7, and a block 18 is provided below the push plate 9, and the outer wall of the block 18 is fixedly connected to both sides of the inner wall of the fixed shell 8;
[0032] In the specific implementation process, it is worth pointing out that, under the cooperation of the spring 10, the push plate 9 and the clamping block 18, when the elliptical wheel 19 rotates to the bottom of the push plate 9 at the narrow position, the push plate 9 will move downward due to the elasticity of the spring 10, so that the clamping plate 3 will contract and clamp the mutual inductor. When the push plate 9 moves, it will be blocked by the clamping block 18 to prevent it from falling off.
[0033] Specifically, on the basis of the above embodiment, when the servo motor 12 is used to drive the elliptical wheel 19 to rotate, the clamp 3 will be extended, and when the protruding end of the elliptical wheel 19 is downward, the push plate 9 will move downward under the action of the spring 10, so that the clamp 3 will shrink and clamp the mutual inductor, and when the push plate 9 moves downward, it will be blocked by the block 18 so that it will not affect the rotation of the elliptical wheel 19.
