[0025] During the use of the present invention, first hold the mounting seat 7 so that the mounting seat 7 drives the rotating seat 3 to rotate in the rotating opening 2. The rotating seat 3 can drive the square block 6 to rotate during the rotation. Due to the sliding connection between the square block 6 and the square opening 5, the square block 6 will drive the threaded block 39 to rotate during the rotation, so the threaded block 39 can rotate in the thread groove 4. When the user stops rotating, the column mounting seat 7 can be smoothly fixed with the help of the thread self-locking ability of the thread groove 4 and the threaded block 39, so that the mounting seat 7 can be adjusted to a suitable angle with the base 1. Then the user can rotate the threaded rod 36. Since the threaded rod 36 threads penetrate the mounting seat 7, when the threaded rod 36 rotates, it will move relative to the mounting seat 7. At the same time, since the threaded rod 36 is rotationally connected to the mounting column 11, and the sliding block 10 fixedly connected to the mounting column 11 is slidably connected to the sliding groove 9 The threaded rod 36 can drive the mounting post 11 to slide closer to or away from the base 1 in the mounting opening 8, so that the mounting post 11 can be smoothly installed and fixed at a suitable position away from the base 1, and then the threaded hole 15 on the rotating ring 14 can be aligned with the corresponding implant welding nail on the sheet metal, and then the threaded tube 40 can be rotated, so that the threaded hole 15 and the implant welding nail are threadedly connected together, so that the installation and fixing work of the threaded tube 40 on the sheet metal is successfully completed, and then the fixing screw 38 can be rotated, and the rotating ring 14 is squeezed by the rotation of the fixing screw 38 in the threaded notch 37, and then the fixing work of the rotating ring 14 and the threaded tube 40 is completed. In this way, the installation and fixing work of the base 1 can be completed with the help of the existing implant welding nail. At this time, the position of the base 1 is different from the implant welding nail, so the subsequent installation work will not be affected by the interference problem of the existing implant welding nail;

[0026] Then, the mounting plate 28 can be rotated as required, so that the mounting plate 28 can be rotated to a suitable position with the help of the rotation of the rotating block 27 in the rotating groove 26, and then the fixing bolt 32 is rotated, and the top seat 16 is squeezed by the rotation of the fixing bolt 32 in the threaded hole 31 and the thread locking, and then the fixing work of the connecting block 30 and the mounting plate 28 is successfully completed, and then the adhesive pad 29 can be adhered to the specified position of the interior trim panel, so that the top seat 16 and the base 1 are aligned at this time. At this time, the alignment position of the top seat 16 and the base 1 is specially set by the user, and there will be no problem of being unable to align and install due to interference problems during installation. Then, the interior trim panel can be aligned and spliced ​​on the sheet metal, so that the limit block 34 is inserted into the limit groove 33, and multiple fixing grooves 17 and multiple storage grooves 1 9 are aligned respectively, and then a magnet can be used to place it on the side surface of the interior trim panel away from the top seat 16 and align it with the top seat 16, so that the magnetic disk 25 can be attracted by the magnetic force of the magnet, so that the magnetic disk 25 drives the fixing seat 18 to overcome the elastic force of the storage spring 20 and insert it into the fixing groove 17. Then, due to the setting of the engaging groove 23, the engaging block 22 loses its restriction and will be inserted into the engaging groove 23 under the elastic force of the engaging spring 24, completing the fixing work of the fixing seat 18 in the fixing groove 17, the fixing work of the base 1 and the top seat 16, and the installation and fixing work of the interior trim panel and the sheet metal parts. At the same time, it will no longer be affected by the interference problem, and there is no need to damage the interior trim panel and the sheet metal parts. When disassembling, only the device will be damaged, and the interior trim panel and the sheet metal parts will not be affected, which is very beneficial to users.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
