[0027] Reference Figure 2 - Figure 5The compacting assembly 3 includes an electric threaded rod 31 fixedly mounted on the top of the display frame 1, and a threaded sleeve 32 is threadedly connected to the surface of the electric threaded rod 31. There are two threaded sleeves 32 and they are symmetrically arranged on the left and right sides of the surface of the electric threaded rod 31. The threads inside the two threaded sleeves 32 are arranged in opposite directions. When the electric threaded rod 31 is driven to rotate, the two threaded sleeves 32 will be driven to move in opposite directions. A vertical rod 33 is fixedly mounted on the bottom end of the threaded sleeve 32, and an elastic rod 34 is fixedly mounted on the rear end of the vertical rod 33. A pressing plate 35 is fixedly mounted on the rear end of the elastic rod 34, and a roller 36 is rotatably connected to the bottom end of the vertical rod 33. A bottom groove 37 is opened at the bottom end of the display frame 1, and rounded corners are arranged on the left and right sides of the pressing plate 35. The roller 36 is rotatably connected to the inside of the bottom groove 37. When the pressing plate 35 moves, the rounded corners arranged on the edge thereof will not cause damage to the poster when it contacts the poster.

[0028] Reference Figure 6 - Figure 7 The limiting component 4 includes an inner groove 41 opened inside the display frame 1, and a slider 42 is slidably connected inside the inner groove 41. A friction rod 43 is fixedly connected to one end of the slider 42 near the edge of the display frame 1. There are four inner grooves 41 and they are respectively located at the four corners of the display frame 1. The display frame 1 is provided with a vertical groove inside the inner groove 41, and the friction rod 43 is slidably connected inside the vertical groove. The position of the slider 42 is limited by the friction force between the friction rod 43 and the vertical groove. A groove body 44 is opened inside the slider 42, and a return spring 45 is fixedly installed inside the groove body 44. A sliding rod 46 is fixedly installed at one end of the return spring 45 near the outside of the groove body 44. An abutment plate 47 is provided at the rear end of the sliding rod 46, and a buffer spring is fixedly installed between the sliding rod 46 and the abutment plate 47. The sliding rod 46 and the vertical rod 33 are adapted to contact, and the elastic force of the buffer spring will push the abutment plate 47 so that the abutment plate 47 abuts against the four corners of the poster to limit the poster.

[0029] Working principle: After the operator places the poster inside the display frame 1, the slider 42 is pushed to slide inside the inner groove 41, so that the slider 42 drives the sliding rod 46 and the abutment plate 47 to move accordingly, so that the abutment plate 47 points to the corner of the poster. At this time, the abutment plate 47 is pushed close to the poster under the action of the elastic force of the buffer spring, so that the abutment plate 47 limits the corner of the poster, and then the four corners of the poster are limited by four abutment plates 47 in the same way;
