The support rods 13 are inserted into the limiting grooves 12. One end of the support rod 13 inserted into the limiting groove 12 is rotatably connected to the first roller 14, and the first roller 14 is rollingly connected to the sub-board 112.

[0032] In this embodiment: when the cost drawing is large, force is applied to the two sub-plates 112 to pull the two sub-plates 112 in opposite directions, and the four first rollers 14 will roll inside the limiting groove 12 due to the pulling of the sub-plates 112 until they move to a suitable position.

[0033] Going further:

[0034] In an optional embodiment, each sub-plate 112 is fixedly connected to the inside with a first spring 15, one end of the first spring 15 away from the sub-plate 112 is fixedly connected to a cushion block 16, one end of the cushion block 16 away from the first spring 15 is rotatably connected to a second roller 17, and the second roller 17 is in contact with the display plate 11.

[0035] In this embodiment: while pulling the auxiliary plate 112, the second roller 17 will rotate on the surface of the display board 11 until the support rod 13 reaches the bending part of the limiting groove 12, and the first spring 15 will push the cushion block 16 toward the display board 11 due to elastic potential energy, and the display board 11 will be forced to move forward.

[0036] Going further:

[0037] In an optional embodiment, two insertion rods 19 are symmetrically fixedly connected to one side of the display board 11 away from the second roller 17, and the interior of each sub-plate 112 is fixedly connected to a limiting block 18. The insertion rod 19 is inserted in the limiting block 18, and one end of the insertion rod 19 inserted in the limiting block 18 is symmetrically fixedly connected to two second springs 111, and each second spring 111 is fixedly connected to a gasket 110 at one end away from the insertion rod 19.

[0038] In this embodiment: the display board 11 will be forced to move forward, and the insertion rod 19 connected to the display board 11 will be inserted into the interior of the limit block 18 with the gasket 110.

[0039] It should be noted that when the display board 11 needs to be folded, the two second springs 111 will shrink due to the squeezing of the limit block 18 on the gasket 110 until they are pulled out from the inside of the limit block 18, and then the two sub-boards 112 are moved closer to the center to achieve shrinkage.

[0040] Going further:

[0041] In an optional embodiment, it further includes a lifting assembly 2 disposed on the bottom surface of the display board 11;

[0042] The lifting assembly 2 includes a supporting shell 21 arranged below the display board 11, and a supporting column 22 is slidably connected inside the supporting shell 21.

The gear 24 is rotatably connected to the supporting shell 21, and a sliding rod 25 is slidably connected inside the gear 24. A rocker 28 is fixedly connected to the end of the sliding rod 25 away from the gear 24.

[0043] In this embodiment: the rocker 28 is rotated with the slide bar 25 as the axis, and the gear 24 sleeved on the surface of the slide bar 25 will rotate inside the tooth groove 23. Due to the shape of the tooth groove 23, the support column 22 and the gear 24 will engage with each other, so that the support column 22 will slide upward inside the support shell 21.

[0044] Going further:

[0045] In an optional embodiment, a card slot 26 is opened inside the supporting shell 21 , and a card block 27 is fixedly connected to the surface of the sliding rod 25 , and the card block 27 is inserted into the card slot 26 .

[0046] In this embodiment: when the device is used, after moving the support shell 21 to an appropriate position, pull the rocker 28, and the slide bar 25 connected to the rocker 28 will slide outward from the inside of the gear 24 until the block 27 connected to the slide bar 25 slides out from the inside of the slot 26, and then the rocker 28 can be turned. After reaching an appropriate height, push the rocker 28, and the slide bar 25 connected to the rocker 28 will drive the block 27 to slide into the inside of the slot 26, and the block 27 is limited by the slot 26 to achieve locking of the support column 22.

[0047] It should be noted that the clamping slot 26 and the clamping block 27 are both in a multi-tooth circular shape for easier clamping.

[0048] Going further:

[0049] In an optional embodiment, two slide grooves 211 are opened inside the support column 22, and an auxiliary rod 210 is inserted into the inside of each slide groove 211. The auxiliary rod 210 and the support column 22 are slidably connected. One end of each auxiliary rod 210 away from the support column 22 is fixedly connected to a positioning block 29, and the two positioning blocks 29 are fixedly connected to the two sub-plates 112.

[0050] In this embodiment, when the two sub-plates 112 are pulled, the positioning block 29 connected to the bottom surface of each sub-plate 112 will slide the auxiliary rod 210 inside the slide groove 211 to support the sub-plate 112.

[0051] It should be noted that the right auxiliary rod 210 is lower than the left auxiliary rod 210 . When the left auxiliary plate 112 is retracted, the left auxiliary rod 210 will be inserted into the right positioning block 29 , and no malfunction will occur.

[0052] The working principle and use process of the utility model are as follows: when using the device, after moving the support shell 21 to a suitable position, pull the rocker 28, and the slide bar 25 connected to the rocker 28 will slide outward from the inside of the gear 24 until the block 27 connected to the slide bar 25 slides out from the inside of the slot 26, and then turn the rocker 28 to make the rocker 28 rotate around the slide bar 25 as the axis, and the gear 24 sleeved on the surface of the slide bar 25 will rotate inside the tooth groove 23. Due to the shape of the tooth groove 23, the support column 22 and the gear 24 will mesh with each other, so that The support column 22 will slide upward inside the support shell 21, and after reaching a suitable height, the rocker 28 is pushed, and the slide bar 25 connected to the rocker 28 drives the block 27 to slide inside the slot 26, and the block 27 is limited by the slot 26 to lock the support column 22. When the cost drawing is large, force is applied to the two sub-plates 112 to pull the two sub-plates 112 in opposite directions. The four first rollers 14 will roll inside the limit slot 12 due to the pulling of the sub-plate 112 until they move to a suitable position. At the same time, the second roller 17 will rotate on the surface of the display board 11 until the support rod 13 reaches the bending part of the limit groove 12. The first spring 15 will push the cushion block 16 toward the display board 11 due to the elastic potential energy. The display board 11 will be forced to move forward, and the insertion rod 19 connected to the display board 11 will carry the gasket 110 into the interior of the limit block 18. Due to the special shape of the limit block 18, the second spring 111 will be compressed, and then the two gaskets 110 will fit the inner surface of the limit block 18 due to the elastic potential energy. The wall is used to fix the display board 11, so that cost drawings of different sizes can be displayed. When the two sub-boards 112 are pulled, the positioning block 29 connected to the bottom surface of each sub-board 112 will slide inside the slide groove 211 with the auxiliary rod 210 to support the sub-board 112. When it needs to be folded, the display board 11 is pressed hard, and the two second springs 111 will shrink due to the squeezing of the gasket 110 by the limit block 18 until they are pulled out from the inside of the limit block 18, and then the two sub-boards 112 are brought closer to the center to achieve shrinkage.
