Embodiment 1

[0030] See also Figure 1-Figure 3 In order to solve the problem that the card slot cannot adapt to the size of the card, this embodiment provides the following technical solutions, an adjustment mechanism is set, and the size of the card slot can be changed by the adjustment mechanism to correspond to cards of different sizes. Specifically disclosed is: a support base 1 is horizontally placed on the ground, and a longitudinally arranged display board 2 is fixedly installed on the upper surface of the support base 1. A teaching card 3 printed with an e-commerce teaching statistical table is installed on the front outer surface of the display board 2, and the teaching card 3 is attached to the outer surface of the display board 2 through positioning blocks 4 on its upper and lower sides, and an adjustment mechanism for changing its installation position is set behind the positioning block 4, and the adjustment mechanism includes a mounting column 5 fixedly installed on the rear surface of the positioning block 4, and the mounting column 5 is engaged with the mounting hole 6 opened on the front surface of the display board 2, and the mounting holes 6 are evenly distributed from top to bottom with equal intervals.

[0031] When using the device to teach e-commerce related content, first, the printed teaching card 3 is attached to the front outer surface of the display board 2 using the positioning block 4. When the positioning block 4 is installed, the mounting column 5 behind it is inserted into the mounting hole 6 to form a snap-fit ​​structure. The mounting holes 6 are evenly distributed from top to bottom with equal intervals, so the mounting columns 5 and the mounting holes 6 at different positions cooperate to form different intervals, thereby adapting to the use of teaching cards 3 of different sizes. Embodiment 2

[0032] See also Figure 4-Figure 6In order to solve the problem of chalk dust flying everywhere, this embodiment provides the following technical solutions, a cleaning mechanism is set, firstly the chalk dust is collected, and then the cleaning mechanism cleans and collects the chalk dust, specifically disclosed: a writing board 7 for writing with chalk is fixedly installed in the middle position of the front outer surface of the display board 2, and a receiving plate 8 is fixedly installed between the lower surface of the display board 2 and the upper surface of the support base 1, and a cleaning mechanism for cleaning chalk dust is arranged inside the receiving plate 8, a negative pressure air pump 10 is fixedly installed on the upper surface of the support base 1, and the negative pressure air pump 10 is connected to the receiving plate 8 through an externally installed connecting hose 11 A connecting structure is formed between them, and the cleaning mechanism includes a filter plate 9 fixedly mounted on the upper end of the inner side of the receiving plate 8 and a dust scraper plate 12 above the filter plate 9, and the lower surface of the dust scraper plate 12 is in contact with the upper surface of the filter plate 9, and a linear slider 13 is fixedly mounted above the dust scraper plate 12 to drive it to move, and a transmission screw 15 rotatably connected to the display board 2 is installed inside the linear slider 13 through a thread, and the linear slider 13 forms a sliding structure with a limiting slide groove 14 opened on the front side of the lower end of the display board 2, and the transmission screw 15 is driven by a small motor 16 fixedly mounted on the side of the display board 2.

[0033] During the teaching process, the teacher can use chalk to write on the writing board 7 to achieve the purpose of auxiliary teaching. When erasing chalk words, the negative pressure air pump 10 above the support base 1 is turned on, and the negative pressure air pump 10 forms a negative pressure inside the receiving plate 8 through the connecting hose 11, thereby adsorbing the fallen chalk dust downward to prevent the chalk dust from flying around (the chalk dust is temporarily retained in the receiving plate 8 under the filtering effect of the filter plate 9). Then the small motor 16 is turned on to drive the transmission screw 15 to rotate. During the rotation process, the transmission screw 15 drives the linear slider 13 installed with a thread passing through its outside to slide inside the limiting slide groove 14, so that the linear slider 13 drives the scraper plate 12 to move synchronously, and the dust temporarily stored inside the receiving plate 8 is scraped into the collection buckets 17 on the left and right sides for storage. Embodiment 3

[0034] See also Figure 7 This embodiment provides the following technical solution, which specifically discloses that: collecting buckets 17 for collecting chalk dust are installed on the left and right sides of the receiving plate 8, and mounting buckles 18 that are engaged with the receiving plate 8 are fixedly installed on the upper surface of the collecting bucket 17.
