[0043] The working principle and use process of the utility model are as follows: when using the device, the mounting seat 1 2 can be first mounted on both sides of the splicing seat 1 so that the engaging seat 21 is engaged in the engaging groove. At this time, the inclined surface of the clamping block 20 is squeezed when the engaging seat 21 slides into the engaging groove, and it will slide into the telescopic cavity 1. At this time, the spring 1 is squeezed, and when the engaging seat 21 is engaged to a suitable position, the clamping block 20 is not squeezed by external force, and the elastic potential energy of the spring 1 will make the clamping block 20 slide and engage in the limiting groove 3 19, thereby completing the installation of the mounting seat 1 2 on both sides of the splicing seat 1. After the mounting seat 1 2 is spliced ​​on both sides of the splicing seat 1, the sliding rod 2 18 is slid, so that the slide plate drives the plugging rod 2 31 to slide into the telescopic cavity 5 32. The engaging block 26 is engaged into the connecting groove, and then the sliding rod 218 is released. At this time, the elastic potential energy of the spring 4 causes the inserting rod 213 to slide into the connecting groove and slide into the engaging block 26, thereby completing the installation of the movable seat 15. The user can adjust the position of the placement seat 10 according to the size of the poster, so that the sliding block 9 installed on one side of the placement seat 10 slides in the sliding groove 13. When the sliding block 9 slides to the appropriate position, the bolt is inserted into the slot 25 and the sliding block 9, and then the bolt is turned to thread the bolt into the limiting card slot 23 at the appropriate position. The position of the relatively installed mounting seat 2 is adjusted according to the width of the poster, and the mounting seat 2 can be relatively pulled. At this time, the sliding rod 1 drives the fixed seat to slide in the telescopic cavity 44, and the card block 1 slides. During the movement, it is squeezed to slide into the telescopic cavity three. At this time, the spring two is in a contracted state. When the mounting seat 2 drives the sliding rod one to slide to the appropriate position, the card block one is not squeezed by external force, and the elastic potential energy of the spring two will be embedded in the limiting card slot two at the appropriate position, thereby limiting and fixing the position of the adjusted mounting seat 2. When it is necessary to adjust the device according to the height of the poster, the squeezing rod can be pressed to make the squeezing rod squeeze the mounting plate, and the mounting plate makes the spring three shrink, and at the same time the insertion rod one is disconnected from the card slot. At this time, the user presses the squeezing rod with the index finger, and then pinches the rotating block 27 with the thumb and middle finger to make the rotating block 27 rotate. The rotating rotating block 27 makes the connecting rod drive the rotating seat 30 to rotate. At this time, the rotating The movable seat 30 drives the rotating rod 29 and the gear 28 to rotate. When the gear 28 rotates, the rack 5 meshing with it will slide upward. When the rack 5 slides to a suitable height, the user first releases the squeezing rod. At this time, the elastic potential of the spring three can make the mounting plate drive the insertion rod 1 to slide toward one side of the rotating seat 30, and it can be engaged in the card slot at a suitable position. At this time, the rotation of the gear 28 can be limited, and the limited gear 28 limits and fixes the height of the rack 5, thereby completing the height adjustment of the device. By adjusting the position of the mounting seat 1 2 and the splicing seat 2 14, the four sides of the poster are respectively engaged in the placement seat 1 10, the placement seat 2 11, and the placement seat 3 12. At this time, rotating the screw can make the clamping plate clamp and fix the four sides of the poster.
