[0024] The specific implementation process of the utility model is as follows: when in use, first place the interior panel on the workbench 4 and then turn the handle 10. The handle 10 drives the screw rod 7 to rotate, so that the screw rod 7 makes a threaded motion, and the screw rod 7 will drive the fixing plate 81 to move down. The fixing plate 81 drives the connecting seat 82 and the positioning ball 83 to move down, so that the positioning ball 83 contacts the interior panel and stops moving. Then the fixing plate 81 continues to move down, and the fixing plate 81 and the connecting seat 82 slide relative to each other.

[0025] When it is necessary to adjust the position of the positioning ball 83, the connecting frame 6 is pushed horizontally, and the connecting frame 6 drives the connecting plate 5 and the slide 91 to move. The slide 91 slides along the guide rod 92, and at the same time, the slide 91 drives the ball 94 to slide along the arc surface of the groove 93. The ball 94 will be squeezed and move in the vertical direction. The ball 94 will drive the connecting block 95 and the connecting rod 96 to move upward, and the connecting block 95 will squeeze the second spring 97 to separate the ball 94 from the groove 93. As the slide 91 translates, the ball 94 can be reset and inserted into the groove 93 at another position under the elastic action of the second spring 97. The position of the slide 91 can be adjusted, and then the horizontal position of the positioning ball 83 can be adjusted, which is convenient for positioning and use of interior trim panels of different sizes.
