The auxiliary cover sheet is located on both sides of the main cover sheet and is located below the main cover sheet when the paper box is closed. The width of the auxiliary cover sheet is usually smaller than that of the main cover sheet, and the function of the auxiliary cover sheet is to enhance the sealing performance (fill the gap between the main cover sheets) or assist in fixing.

[0003] When the paper box is closed, the distance between the upper surface of the paper box bottom plate and the lower surface of the auxiliary cover sheet is the internal height of the paper box. The internal height of the paper box is one of the most important parameters of the paper box. In the prior art, two persons are required to cooperate to measure the internal height of the paper box. One person presses the main cover sheet and the auxiliary cover sheet to prevent them from being lifted to simulate the closed state of the paper box, and the other person uses a tape measure to measure the height data from the upper surface of the paper box bottom plate to the lower surface of the auxiliary cover sheet to complete the measurement of the internal height of the paper box.

The stand 4 is in the shape of a round rod, and the stand 4 is vertically arranged on the base plate 3. The stand 4 is marked with a main scale 41 along the length direction thereof. The main scale 41 is marked from the bottom of the stand 4 upwards, and the scale represents the distance from the corresponding position to the lower bottom surface of the base plate 3. A first sleeve 5 and a second sleeve 6 are slidably arranged on the stand 4. The first sleeve 5 is fixed with a pressing rod 52. The second sleeve 6 is located below the first sleeve 5, and the second sleeve 6 is fixed with a measuring rod 62.

The height of the pressing rod 52 and the measuring rod 62 is adjusted, the pressing rod 52 is pressed on the upper surface of the main cover piece 1, and the main cover piece 1 is prevented from being buckled. If the paper box is too large, the second pressing rod 523 folded on the first pressing rod 522 can be unfolded, so as to increase the length of the pressing rod 52. In addition, since the stand 4 is a round rod, the pressing rod 52 can rotate in a plane, and the pressing rod 52 can be rotated to a suitable angle and then fixed. The measuring rod 62 is adjusted to be in contact with the bottom surface of the auxiliary cover piece 2. The end of the measuring rod 62 close to the stand 4 is provided with an auxiliary scale 8.
