The covering plate 8 is movably sleeved on the surface of the corresponding fitting strip 9.

[0029] During specific operation, the main shell panel 101 on the interior trim body 1 is sleeved on the column body 201 of the B-pillar body 2, and the side shell panels 102 on both sides of the main shell panel 101 are forced to slide along the surfaces of the side skirt panels 202 on both sides of the column body 201, so that the engaging strips 9 on the side shell panels 102 can finally engage with the covering sleeve panel 8, thereby preliminarily fixing the interior trim body 1 on the B-pillar body 2.

[0030] See also Figure 4 , Figure 5 and Figure 6 A locking piece 3 is provided at the middle position of one side of the interior decoration body 1 close to the B-pillar body 2. The locking piece 3 includes two fixing seats 301 fixedly provided on one side of the main shell plate 101 close to the B-pillar body 2 and symmetrically on the left and right. A locking bolt 302 is threadedly provided on the fixing seat 301. The locking bolt 302 is movably plugged into the main shell plate 101. The two locking bolts 302 are commonly threadedly connected to the same connecting plate 303. Two symmetrical threaded sleeves 304 are fixedly provided on one side of the column body 201 close to the locking piece 3. The threaded sleeves 304 correspond to the locking bolts 302 one by one.

[0031] During specific operation, after the side shell plate 102 is pressed to a predetermined position, the end position of the locking bolt 302 is aligned with the end of the threaded sleeve 304, and then the two locking bolts 302 are rotated simultaneously from the rear side of the main shell plate 101, so that the two locking bolts 302 are screwed into the threaded sleeve 304, further fixing the main shell and the column body 201.

[0032] See also Figure 5 , Figure 6 and Figure 7A connecting member 4 is provided between the locking member 3 and the left and right sides of the interior decoration member body 1. The connecting member 4 includes two rotating rods 401 respectively rotatably provided on the left and right sides of the interior decoration member body 1, and a connecting frame 402 with a U-shaped structure is fixedly provided on the rotating rods 401.
