[0020] The adjusting assembly 6 includes a strip frame 7, which is fixedly installed at the bottom center of the mounting top frame 1. The bottom of the strip frame 7 is an open structure. A bidirectional screw 8 is rotatably installed inside the strip frame 7, and one end of the bidirectional screw 8 extends to the outside of the strip frame 7. An adjusting block 9 is fixedly installed at the end of the bidirectional screw 8 located outside the strip frame 7. A locking screw 10 is movably installed through the end of the strip frame 7 away from the adjusting block 9, and one end of the locking screw 10 is fixedly connected to the end of the bidirectional screw 8 away from the adjusting block 9. A circular stop block 11 is fixedly installed at the end of the locking screw 10 away from the bidirectional screw 8. A locking nut 12 is threaded on the outside of the locking screw 10, and one side of the locking nut 12 contacts the outside of the strip frame 7.

[0021] A threaded sleeve 13 is symmetrically threaded inside the strip frame 7 and outside the bidirectional screw 8. A positioning slider 24 is symmetrically fixedly installed on the outside of the threaded sleeve 13. A positioning groove 25 is symmetrically opened through the outside of the strip frame 7, and the positioning slider 24 is slidably installed through the positioning groove 25. A first connecting shaft 14 is fixedly installed at the bottom of the threaded sleeve 13. A first movable strip 15 is rotatably installed on the first connecting shaft 14. A first movable shaft 16 is rotatably installed at the end of the first movable strip 15 away from the first connecting shaft 14. A connecting rod is fixedly installed at the bottom of the first movable shaft 16. The connecting frame 17 is fixedly installed on the top of the spring damper 5.

[0022] During use, the interaction of the mounting bracket 1, adjusting component 6, spring damper 5, and support bracket 3 enables the busbar seismic support to achieve adaptive multi-level adjustment of vertical height according to actual needs, ensuring better usability and practicality. Furthermore, the interaction of the positioning slider 24 and positioning groove 25 ensures better stability of the threaded sleeve 13 during movement, thereby ensuring the stable operation of the adjusting component 6.

[0023] Working principle: During operation, the mounting bracket 1 is first fixedly installed using mounting bolts that match the diameter of the mounting hole 2. Then, the locking nut 12 is loosened to release the positioning of the locking screw 10, thereby releasing the positioning of the bidirectional screw 8. Then, the adjusting block 9 is rotated to drive the bidirectional screw 8 to rotate. The bidirectional screw 8 drives the threaded sleeve 13 to move. The threaded sleeve 13 drives the positioning slider 24 to slide inside the positioning groove 25, which can ensure better stability of the threaded sleeve 13 during movement. At the same time, the threaded sleeve 13 drives the first connecting shaft 14 to move. The first connecting shaft 14 drives the first movable bar 15 to move. The first movable bar 15 pushes the connecting frame 17 downward through the first movable shaft 16. The connecting frame 17 drives the second connecting shaft. The second connecting shaft 18 moves downward, driving the second movable bar 19 to move. The second movable bar 19, through the second movable shaft 20, drives the positioning sleeve 21 to slide on the outside of the positioning slide rod 22, ensuring better stability of the connecting frame 17 during movement. At the same time, the connecting frame 17 drives the spring damper 5 to move downward, and the spring damper 5 pushes the support bracket 3 downward. After the support bracket 3 moves to the required height, the rotation of the adjusting block 9 is stopped, and then the locking nut 12 is tightened to reposition the bidirectional screw 8. This allows the busbar seismic support to achieve adaptive multi-level adjustment of vertical height according to actual needs during use, ensuring better use and thus facilitating better practicality.
