Slots 22 are provided on both sides of the mounting plate 21. Two groups of mounting cards 31 are respectively clamped in these slots 22, providing a basis for subsequent rotation operations. The mounting cards 31 are rotatably connected to the mounting plate 21, endowing the entire device with a certain degree of flexibility and adaptability. Multiple groups of mounting holes 32 are provided on the mounting cards 31, and bolts can pass through the mounting holes 32, enabling the mounting position and angle to be adjusted according to actual needs, providing convenience for the entire device in different installation environments. Multiple groups of fixing components are provided on both sides of the mounting plate 21, and the fixing components ensure the stable installation of the device. A wire groove 13 is provided at the top of the high-insulation ceramic body 11, which is used to neatly accommodate and guide wires, avoiding the chaotic distribution of wires, and improving the neatness and safety of the circuit layout.

[0025] As Figure 2 、 3 shown, the fixing component includes a suction cup 41. Multiple groups of connecting plates 23 are provided on both sides of the mounting plate 21. A connecting sleeve 24 is provided on the connecting plate 23, and the suction cup 41 is connected to the bottom of the connecting sleeve 24. This not only ensures the stable combination between the suction cup 41 and the connecting plate 23, but also provides a basis for the suction cup 41 to effectively exert its adsorption function. The suction cup 41 can be in close contact with the installation surface, thereby generating a strong adsorption force and enhancing the fixing effect of the entire device.

[0026] The fixing component further includes a rotating rod 42. Two groups of connecting cards 25 are provided on the connecting plate 23. The rotating rod 42 is located between these two groups of connecting cards 25. Connecting holes are provided on both the rotating rod 42 and the connecting cards 25. A connecting shaft passes through the connecting holes, enabling a rotatable connection between the rotating rod 42 and the connecting cards 25. This allows the rotating rod 42 to rotate freely within a certain range, thereby providing the possibility to adjust the position and angle of the suction cup 41.

[0027] A connecting rod 43 is further provided on the suction cup 41, and the connecting rod 43 is also rotatably connected to the rotating rod 42. By controlling the rotating rod 42, a negative pressure cavity is generated between the suction cup 41 and the ground, enabling the device to be firmly fixed on the ground.

[0028] As Figure 2 、 4As shown, the corresponding surfaces of the fixed base 12 and the mounting plate 21 are provided with mounting grooves 14, and the two groups of mounting grooves 14 cooperate with each other to form an I-shaped slide. The I-shaped slide block 33 is clamped in this I-shaped slide.

During the operation of the device, the heat generated inside can be quickly dissipated to the outside environment through the heat dissipation slots 18, effectively reducing the internal temperature, avoiding performance degradation or failures that may be caused by overheating, and ensuring the long-term stable operation of the device.

[0032] Specific usage and function of this embodiment:

[0033] During use, align the fixed base 12 at the bottom of the high-insulation ceramic body 11 with the mounting plate 21, engage the I-shaped slider 33 into the I-shaped chute, and use a fixing bolt to pass through the fixing hole for fixation. Snap the mounting clip 31 into the card slots 22 on both sides of the mounting plate 21, adjust the angle of the mounting clip 31 through the rotating shaft 35, select a suitable mounting hole 32 according to the actual installation environment, and use bolts to fix the mutual inductor at the designated position. Place the wire to be measured into the wire groove 13 at the top of the high-insulation ceramic body 11, ensuring that the wires are neatly arranged to avoid chaotic distribution. When fixing the device, connect the suction cup 41 to the connecting plates 23 on both sides of the mounting plate 21 through the connecting sleeve 24. Rotate the rotating rod 42 and the connecting rod 43 to adjust the position and angle of the suction cup 41 so that it is in close contact with the installation surface, forming a negative pressure cavity to enhance the fixing effect of the device. For the limiting plate 15 on one side of the fixed base 12, according to the direction and layout of the connecting wire, rotate the limiting plate 15 to a suitable angle and position, and snap both ends of the roller 34 into the limiting groove 16 to ensure that the connecting wire is located between the rollers 34 so that it can slide smoothly during movement or when stressed. During the operation of the device, the installation cavity 17 inside the high-insulation ceramic body 11 can protect key components, and the generated heat will be dissipated to the outside through the heat dissipation grooves 18 to ensure the long-term stable operation of the device.

[0034] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments.
