The connecting screw 21 is passed through the first strip hole 111 and connected to the clip 2. At this time, it is not tightened, so that the clip 2 can still slide. The screw 4 is passed through the second through hole 112 to the inner cavity 11 and is threadedly connected to the connecting member 3, so that the main connecting member 3 is first fixed in the inner cavity 11, and the clip 2 is retracted into the inner cavity 11, and the main fixing member 1 is completely passed through the installation groove 900. Put it into the frame profile 99, and then pull the connecting screw 21 to make the clip 2 extend into the inner cavity 11. At this time, you can lock the connecting screw 21 to fix the clip 2, and then turn the screw 4 to make the screw 4 pass through the back of the main fixing part 1 and press against the inner side of the frame profile 99. Since the frame profile 99 and the screw 4 are pressed against each other, the screw 4 cannot continue to move, and then as the screw 4 is turned, the main fixing part 1 is lifted up, so that the extended clip 2 is tightly pressed against the back of the installation surface of the frame profile 99. At this time, the main fixing part 1 is installed.

The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
