[0029] In the embodiment, the adjusting mechanism comprises a connecting plate 5 connected with the bottom end of the fixed plate 1, a connecting frame 6 connected with the connecting plate 5, a first worm wheel 9 fixedly connected with the connecting frame 6 through a connecting shaft 13, a fixed block 7 connected with the top end of the lifting platform 4, a first worm 8 connected with the fixed block 7, the first worm 8 is meshed and connected with a second worm wheel 14, the connecting frame 6 is provided with an extension column on the left and right sides of the bottom end, the first worm 8 penetrates the fixed block 7 and the extension column in sequence and is rotationally connected therewith, the connecting plate 5 is in the shape of “U”, the top end thereof is fixedly connected with the fixed plate 1, and the bottom end thereof is fixedly connected with both ends of the connecting shaft 13, the lifting platform 4 is provided with a through hole, the through hole is connected with a guide column 12 penetratingly, the bottom end of the guide column 12 penetrates the top end of the support platform 3 and is fixedly connected with the support platform 3, the top end of the lead screw 11 is located in the lifting platform 4 and is rotationally connected with the lifting platform 4, the bottom of the lead screw 11 is located in the support platform 3 and is threadedly connected with the support platform 3, the top end of the lead screw 11 is connected with the second worm wheel 14, and the front end of the lifting platform 4 is connected with a second worm 10 penetratingly and the second worm 10 is meshed and connected with the second worm wheel 14.

[0030] The "U"-shaped design of the connecting plate 5 increases the stability and reliability of the connection with the fixing plate 1, effectively disperses the stress, ensures smooth transmission of force between the fixing plate 1 and the subsequent adjusting components, makes the connection of the entire structure more firm and facilitates the conduction of force, enables the angle adjustment of the fixing plate 1 to be realized through the connecting frame 6 and the internal worm and gear mechanism, the internal connecting frame 6 is fixedly connected with the first worm wheel 9 through the connecting shaft 13, which provides a space frame for the installation and rotation of the first worm wheel 9, the first worm wheel 9 is fixed in the connecting frame 6 through the connecting shaft 13, the first worm 8 is connected with the fixing block 7 and engages with the first worm wheel 9, and the first worm wheel 9 can be slowly and stably driven to rotate by rotating the first worm 8, thereby realizing the fine adjustment of the angle of the fixing plate 1. Secondly, the worm and gear transmission has self-locking property, and when adjusted to the appropriate angle, even without additional locking device, the worm wheel can remain at the current position without external force driving the worm to reverse, preventing the angle of the fixing plate 1 from accidentally changing. The first worm 8 penetrates and rotates the fixing block 7 and the extension column in sequence, and the extension column provides an additional support point for the first worm 8, further enhancing the stability of the first worm 8 during rotation, reducing the possibility of bending deformation, and ensuring the smoothness and reliability of transmission. The guiding column 12 provides precise guidance for the lifting movement of the lifting platform 4, preventing the lifting platform 4 from deviating or rotating during the lifting movement driven by the lead screw 11, ensuring that the lifting platform 4 can only move vertically along the axis of the guiding column 12, thereby ensuring the positional accuracy of the combined mutual inductor during height adjustment, avoiding the deviation of the installation position of the combined mutual inductor or collision with other components due to unstable movement of the lifting platform 4. The lead screw 11 is rotatably connected at the top end inside the lifting platform 4 and at the bottom end inside the support platform 3 and is threadedly connected with the support platform 3. This connection allows the support platform 3 to remain relatively stationary while the lifting platform 4 moves up and down along the axis of the lead screw 11 when the lead screw 11 rotates due to the action of the threads. The second worm wheel 14 connected to the top end of the lead screw 11 and the second worm 10 engaged with the second worm wheel 14 and penetrating the front end of the lifting platform 4 form another worm and gear transmission pair for controlling the rotation of the lead screw 11. By rotating the second worm 10, the second worm wheel 14 and the lead screw 11 can be rotated to achieve precise adjustment of the height of the lifting platform 4. Similarly, the self-locking property of the second worm wheel 14 also helps to lock the position of the lifting platform 4 after adjusting to the appropriate height, preventing accidental lowering due to gravity or external factors, and ensuring the stability of the installation height of the combined mutual inductor.

[0031] Working principle:

[0032] When it is necessary to adjust the angle of the fixed plate 1 to adapt to special installation requirements, the operator rotates the first worm 8, since the first worm 8 is engaged with the first worm wheel 9 fixed in the connecting frame 6 through the connecting shaft 13, the rotation of the first worm 8 will drive the first worm wheel 9 to rotate slowly around the connecting shaft 13, since the connecting plate 5 is in the shape of "U", the bottom end is fixedly connected with the both ends of the connecting shaft 13, and the top end is fixedly connected with the fixed plate 1, so the rotation of the first worm wheel 9 will change the included angle of the fixed plate 1 relative to the adjusting mechanism, the precise fine adjustment of the angle of the fixed plate 1 is realized, and since the self-locking property of the worm and worm wheel transmission, after the angle is adjusted, even if there is no additional locking device, the fixed plate 1 can also remain stable, and will not change the angle due to slight interference from the outside, the first worm 8 penetrates through the fixed block 7 and the extension columns at the bottom ends of the left and right sides of the connecting frame 6 in sequence and is rotationally connected, the extension columns provide better support and stability for the first worm 8, and guarantee the stability and reliability of transmission during the whole angle adjustment process;
