Using the installation buckle for automobile interior, the installation holes on the interior parts will not be squeezed and polished during the entire insertion and removal process, which is conducive to improving the stability of interior installation.

[0026] Specifically, the rotary drive mechanism 9 includes a gear 901, a driving rod 903, a driven rod 904 and a first connecting block 913. The gear 901 is movably connected to the side wall of the straight slot 11 through a rotating rod 902. The driving rod 903 and the driven rod 904 are respectively arranged on the top surface and the bottom surface of the straight slot 11 and are respectively fixed with a plurality of first racks 905 and a plurality of second racks 906 on one end surface close to the gear 901. A first inclined groove 907 is formed at one end of the driving rod 903 and a second circular groove 909 is formed at the other end. One end of the driven rod 904 extends to the outside of the straight slot 11 and is fixed with a bearing block 911. A second connecting block 912 is fixed on the side of the bearing block 911. The first connecting block 913 is fixed to the top of the limiting flap 13 and is movably connected to the second connecting block 912 through a rotating shaft 914. A plurality of round rods 908 are fixed to the inner wall of the ring 12. The number of round rods 908 and the second circular grooves 909 are the same and correspond one to one. The other end of the round rods 908 is located in the second circular groove 909 and connected to it through a second spring 910.

[0029] Furthermore, the maximum distance between the two first arc plates 18 is smaller than the outer diameter of the limiting ring 12, and the maximum distance between the two second arc plates 20 is also smaller than the outer diameter of the limiting ring 12, so as to prevent the first arc plates 18 and the second arc plates 20 from being too large to be inserted and installed.

[0030] Furthermore, the bottom ends of the plurality of movable rods 19 are all fixed with limiting blocks 22 to prevent the movable rods 19 from being disconnected from the first arc-shaped plate 18 .

[0031] Furthermore, the number of the straight slots 11 and the limiting flaps 13 are the same and correspond one to one, so that the limiting flaps 13 can be rotated.

[0032] Furthermore, a washer 23 is provided between the support rod 14 and the limiting flap 13 , and the washer 23 is slidably connected to the slide rod 17 to prevent the limiting flap 13 from sliding back and forth on the slide rod 17 and affecting the stability of the installation of the female buckle 2 .

[0033] The working principle of the present invention is as follows: when the female buckle 2 is removed and installed, the screw rod 102 is first threadedly connected with the driving ring 8 so that it drives the driving ring 8 to move downward and squeeze the multiple driving rods 903 to move outward. At this time, the multiple first racks 905 are meshed with the gear 901 to make the gear 901 rotate and meshed with the multiple second racks 906. Finally, the multiple driven rods drive the limiting petals to rotate for removal and installation; when the female buckle 2 needs to be pulled out, the screw rod 102 is rotated in the opposite direction so that it drives the driving ring 8 to move upward and no longer squeezes the driving rod 903. The multiple driving rods 903 are reset under the elastic action of the second spring 910. At this time, the driven rod 904 drives the limiting petal 13 to reset, and the female buckle 2 can be pulled out.

[0034] During the entire insertion and removal process, the mounting holes on the interior trim will not be squeezed or polished, which is beneficial to improving the stability of the interior trim installation.

[0035] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention.
