The lower column 1021 is a hollow rectangular parallelepiped with an opening at the top. The lower part of the upper column 1022 is slidably connected to the interior of the lower column 1021. A slider is installed on the lower side wall of the upper column 1022, and a slide groove is provided on the inner wall of the lower column 1021. The sliding of the upper column 1022 is achieved by the slider and the slide groove.

[0036] A plurality of first plug holes 1023 are provided along the vertical direction on two opposite side walls of the lower column 1021, and a plurality of second plug holes 1024 are provided along the vertical direction on two opposite side walls of the upper column 1022. When the height of the column 102 is adjusted, after the upper column 1022 is moved to a suitable position, the limiting rod 1025 is inserted into the first plug hole 1023 and the second plug hole 1024, and the limiting rod 1025 is threadedly connected to the first plug hole 1023 and the second plug hole 1024 to fix the upper column 1022. The number of limiting rods 1025 can be set as needed.

[0037] The position of the upper column 102 can be adjusted manually, or an electric lifting device can be installed inside the lower column 1021 to adjust the movement of the upper column 1022 using the electric lifting device.

[0039] Example 3

[0040] A working platform for an online detection device of a tobacco production line. The technical solution in this embodiment is basically the same as that in Embodiment 2, except that the structure of the mounting frame 6 in this embodiment is different.

A connecting plate 604 is fixed to the side wall of the bottom plate 602, and the connecting plate 604 is slidably connected to the side wall of the lower column 1021 of one of the columns 102. A slide groove 1026 is provided on the side wall of the lower column 1021 of one of the columns 102, and the connecting plate 604 is slidably connected in the slide groove 1026. When in use, the sliding connecting plate 604 can be adjusted according to the height of the transmission belt 8 to adjust the position height of the top plate 601 so that the height of the material test tray 7 is consistent with that of the transmission belt 8.

Through holes are respectively provided on the four corners of the bottom plate 602, and the bolts 605 are threadedly connected in the through holes. The bottom of the bolts 605 is fixed to the supporting plate 606.

[0043] When adjusting the height of the material test tray 7, slide the connecting plate 604 to move the bottom plate 602 upward, turn the bolt 605 to make the bottom of the support plate 606 fit closely with the ground, and support the mounting frame 6. The connecting plate 604 can ensure that the material test tray 7 moves only in the vertical direction and does not move in the horizontal direction when adjusting the height, and ensure that the center point of the instrument mounting seat 3 and the dividing point of half of the radius of the material test tray 7 are always on the same straight line during the adjustment process.
