In this embodiment, the side of the first box is connected to the side of the second box through an adjusting device, an allen wrench is inserted into the operation through hole 1211 of the rotating block 121 and pressed downward to overcome the elastic force of the elastic element 16, so that the rotating block 121 is switched from the rotation stop position to the driving position, the rotating block 121 is rotated, the rotating block 121 drives the rotating element 12 to rotate clockwise around the front-back direction (the Z-axis direction shown in fig. 19) in the first mounting hole 111, and the adjusting latch hook 13 rotates around the Z-axis, when the rotating block rotates by 90 °, the latch hook section 132 is matched with the latch slot 222 to enable the adjusting latch hook 13 to be in the locking position, thereby completing the connection and fixation of the first box and the second box.

The driving rod 143 of the first box is rotated clockwise or counterclockwise by the allen wrench, so as to drive the second driving block 142 to move in the front-back direction (the positive direction of the Z axis or the negative direction of the Z axis shown in fig. 19), and thus drive the adjusting latch hook 13 to move in the left-right direction (the positive direction of the X axis or the negative direction of the X axis shown in fig. 19). The second box body is driven to move in the left-right direction by the pushing force or the pulling force of the locking hook section 132 of the adjusting locking hook 13 on the first box body on the rod body 221 on the second box body, and finally the gap adjustment of the first box body and the second box body in the left-right direction is realized.

The adjusting rod 22 on the second box body is rotated clockwise or anticlockwise by using an allen wrench, so that the adjusting rod 22 moves along the front-back direction (the positive direction of the Z axis or the negative direction of the Z axis), and the adjusting locking hook 13 on the first box body is pushed or pulled to move back and forth along the front-back direction through the matching action of the locking groove 222 on the adjusting rod 22 on the second box body and the locking hook section 132 on the first box body, so that the first box body is driven to move relative to the second box body along the front-back direction, and finally, the height difference between the first box body and the second box body in the front-back direction is adjusted.

In addition, the number of the box bodies 1 is four, when the number of the adjusting devices is four, one box body above the first box body is a third box body, one box body above the second box body is a fourth box body, the side part of the third box body is connected with the side part of the fourth box body through another adjusting device, the driving rod on the third box body is rotated clockwise or anticlockwise through the hexagon socket wrench, the driving block is driven to move along the front-back direction (the positive direction of the Z axis or the negative direction of the Z axis shown in fig. 19), and therefore the adjusting lock hook is driven to move along the up-down direction (the positive direction of the Y axis or the negative direction of the Y axis shown in fig. 17). The fourth box body is driven to move along the up-down direction by the pushing force or the pulling force of the locking hook section of the adjusting locking hook on the third box body on the rod body on the fourth box body, and finally the gap adjustment of the third box body and the fourth box body in the up-down direction is realized.
