The machine base 1 is equipped with an adjustment unit 13 for adjusting the angle of the viewing plate 2. The two ends of the moving rod 4 are fixedly connected to the second moving plate 14. The upper part of the viewing plate 2 is provided with a first moving groove 15 that is adapted to the second moving plate 14. The upper part of the viewing plate 2 is also provided with a first adjustment groove 16 that communicates with the first moving groove 15. The upper part of the second moving plate 14 is fixedly connected with a first stud 17 that passes through the first adjustment groove 16. The side of the first stud 17 is threaded with a first limiting nut 18. The side of the moving rod 4 is provided with a second moving groove 20 that is adapted to the first moving plate 5. The upper part of the first moving plate 5 is fixedly connected with a second stud 19. The upper part of the moving rod 4 is provided with a second adjustment groove 21 that communicates with the second moving groove 20 and is adapted to the second stud 19. The side of the second stud 19 is threaded with a second limiting nut 22.

[0032] The specific implementation method in this embodiment is as follows: When it is necessary to use this device to inspect printing machine samples, firstly, the two moving rods 4 are moved on the inspection plate 2 according to the size of the printing machine sample. The distance between the two moving rods 4 is slightly larger than the width of the sample. When the moving rods 4 move, the second moving plate 14 moves in the first moving groove 15, and at the same time, the first stud 17 moves in the first adjusting groove 16. After the position of the moving rods 4 is adjusted to a suitable position, the first limiting nut 18 is tightened to limit and fix the position of the second moving plate 14. The position of the first moving plate 5 is moved according to the length of the sample. The first moving plate 5 moves in the second moving groove 20, and at the same time, the second stud 19 moves in the second adjusting groove 21. Several first moving plates 5 are moved to a position that matches the sample length. The sample is positioned correctly, and the second limiting nut 22 is tightened to limit and fix the position of the first moving plate 5. The clamping frame 6 is pulled away from the first moving plate 5. At this time, the insertion block 10 moves in the insertion slot 11, and the elastic band 12 is stretched. Then, the pulling rod 8 is pulled away from the clamping frame 6. At this time, the elastic sheet 9 is compressed, and the corner of the sample is placed in the clamping frame 6. The pulling rod 8 is released, and the elastic force of the elastic sheet 9 squeezes the pressing plate 7 to clamp the sample. At the same time, the clamping frame 6 is released, and the contraction force of the elastic band 12 drives the clamping frame 6 closer to the first moving plate 5, flattening the sample for easy inspection. In addition, there are several clamping frames 6, which can clamp and flatten multiple samples, making it easy for inspectors to compare the samples.

[0034] Please see Figure 2 , Figure 5 , Figure 6 and Figure 7 This embodiment includes the above-described embodiment, wherein the adjustment unit 13 includes an adjustment seat 23 slidably connected to the upper part of the machine base 1. The upper part of the machine base 1 has a sliding groove 24 adapted to the adjustment seat 23. A connecting rod 26 is rotatably connected between the upper part of the adjustment seat 23 and the lower part of the sample plate 2. A rotating groove 27 is provided on the front side of the machine base 1. An adjustment screw 25 is rotatably connected in the sliding groove 24, with one end extending into the rotating groove 27. The adjustment screw 25 passes through the adjustment seat 23 and is threadedly connected to it. The adjustment screw 25 is located in the rotating groove 27. A polygonal-shaped limiting sleeve 33 is fixedly connected to one side of the moving groove 27. A rotating disk 28 is fitted on the side of the limiting sleeve 33.

When the angle of the viewing plate 2 needs adjustment, hold the rotating rod 34 and push the rotating disk 28 towards the sliding groove 24. The rotating disk 28 slides on the side of the limiting sleeve 33. When the limiting groove 30 disengages from the limiting block 31, the rotating disk 28 can be rotated by the rotating rod 34. When the rotating disk 28 rotates, it drives the adjusting screw 25 to rotate, and when the adjusting screw 25 rotates, it drives... The movable adjustment seat 23 slides in the sliding groove 24. When the adjustment seat 23 moves, the angle of the connecting rod 26 changes, thereby adjusting the angle of the viewing sample 2. When the angle of the viewing sample 2 is adjusted to a suitable position, the rotating rod 34 is released. At this time, the tension of the spring 32 pushes the rotating disk 28 to move towards the limiting block 31. The limiting groove 30 engages with the limiting block 31, and the baffle 29 limits the rotating disk 28, thereby limiting the angle of the viewing sample 2, making it convenient for the viewing personnel to adjust the angle of the viewing sample 2.
