A stable fastener for automotive interior installation includes: a hexagonal block 5. On one external side of the hexagonal block 5, a threaded post 4 is fixedly installed. Threaded grooves 6 are provided inside both the threaded post 4 and the hexagonal block 5. Mounting holes 7 are provided on the external side of the threaded post 4, and the number of the mounting holes 7 is two. Steel balls 8 are installed inside both of the two mounting holes 7. A second baffle 12 is slidably installed inside the threaded groove 6. On one external side of the second baffle 12, a tapered block 11 is fixedly installed. One end of the tapered block 11 is fixedly installed with a first baffle 10. The threaded post 4 is fixed to the vehicle. During the driving process of the vehicle, vibrations are likely to occur, and the vibrations are likely to cause the threaded post 4 to become loose. If not tightened in time, the interior trim will fall off, which is relatively dangerous during the driving process. Through the movement of the tapered block 11, the steel balls 8 are effectively pushed outwards of the mounting holes 7, thereby locking the threaded post 4 to the vehicle, preventing the threaded post 4 from becoming loose, and thus avoiding the loosening of the interior trim, improving safety.

[0020] One end of the first baffle 10 is fixedly installed with a screw rod 9. The screw rod 9 is adapted to the threaded groove 6. A hexagonal hole 13 is provided at one end of the screw rod 9. Insert a hexagonal tool into the interior of the hexagonal hole 13 and rotate the hexagonal tool to drive the screw rod 9 to rotate. The rotation of the screw rod 9 drives the tapered block 11 to move. The first baffle 10 and the second baffle 12 effectively play a blocking role to prevent the steel balls 8 from falling off, improving practicability.

[0021] One end of the threaded post 4 penetrates through a mounting member 1. On one external side of the mounting member 1, a mounting groove 2 is provided. The steel balls 8 are in contact with the tapered block 11. The hexagonal block 5 is located inside the mounting groove 2.

If it is not tightened in time, the interior trim may fall off, which is quite dangerous during driving. Insert a hexagonal tool into the interior of the hexagonal hole 13 and rotate the hexagonal tool to drive the screw rod 9 to rotate. The rotation of the screw rod 9 drives the conical block 11 to move. The first baffle 10 and the second baffle 12 effectively play a blocking role to prevent the steel balls 8 from falling off, improving the practicality. Through the movement of the conical block 11, the steel balls 8 are effectively pushed outwards from the installation hole 7, thereby tightening the threaded post 4 to the vehicle, preventing the threaded post 4 from loosening, and further avoiding the loosening of the interior trim, improving safety.
