When the device is not in use, the two support plates 116 are rotated to be stored in the storage groove 117, thereby reducing the occupied space and facilitating home use.

[0034] Second embodiment:

[0035] Based on the first embodiment, please refer to Figure 7 and Figure 8 , Figure 7 is a schematic diagram of the installation structure of the locking column of the second embodiment, Figure 8 2 is a schematic diagram of the installation structure of the button of the second embodiment. The locking member 108 of this embodiment includes a locking spring 202 , a locking column 201 and a button 205 . The locking column 201 includes a column 203 and a ball 204 .

[0036] According to this specific embodiment, the locking spring 202 is connected to the sliding frame 103 and is located inside the sliding frame 103; the locking column 201 is connected to the locking spring 202 and is arranged on the locking spring 202; a locking groove is also arranged on the outer shell 101. When the teacher pulls the sliding frame 103 upward, the sliding frame 103 moves upward, and at the same time drives the locking column 201 to move. When the locking column 201 is aligned with the locking groove on the outer shell 101, the locking column 201 extends into the locking groove under the action of the locking spring 202, thereby fixing the sliding frame 103 and the whiteboard 104.

[0037] Among them, the column 203 is connected to the locking spring 202, and is slidably connected to the sliding frame 103, and is located at one end of the locking spring 202; the ball 204 is rotationally connected to the column 203, and is located on the side of the column 203 away from the locking spring 202; through the rotation of the ball 204, the friction between the locking column 201 and the housing 101 is reduced, making it convenient for the teacher to pull out the sliding frame 103 and the whiteboard 104.

[0038] Secondly, the button 205 is slidably connected to the shell 101 and is arranged on the shell 101; the button 205 is arranged at the locking groove. When the whiteboard 104 needs to be retracted into the shell 101, the button 205 is pressed and the locking column 201 is driven to move. When the locking column 201 moves out of the shell 101, the sliding frame 103 and the whiteboard 104 can descend under the action of gravity and then be retracted into the shell 101.

[0039] Third embodiment:

[0040] Based on the first embodiment, please refer to Fig. 9 , Fig. 9 3 is a schematic diagram of the installation structure of the buffer spring of the second embodiment. The buffer component 110 of this embodiment includes a buffer spring 301 , a buffer plate 302 and a damper 303 .

[0041] According to this specific embodiment, the buffer spring 301 is connected to the outer shell 101 and is located inside the outer shell 101; the buffer plate 302 is connected to the buffer spring 301 and is located at one end of the buffer spring 301; the number of the buffer plates 302 is consistent with the number of the sliding frames 103, and a plurality of the buffer springs 301 are arranged on one buffer plate 302. When the sliding frame 103 and the whiteboard 104 descend under the action of gravity, the sliding frame 103 falls on the buffer plate 302, and the impact force is buffered by the buffer spring 301 to avoid damage to the outer shell 101 or the whiteboard 104.

[0042] The two ends of the damper 303 are respectively connected to the shell 101 and the buffer plate 302, and the damper 303 is located inside the shell 101; the reciprocating movement of the buffer plate 302 is limited by the damper 303 to prevent the reciprocating movement of the buffer spring 301 from causing the sliding frame 103 to reciprocate up and down.

[0043] When using the auxiliary teaching device for online teaching of the present invention, when the teacher writes on the blackboard, the handle above the sliding frame 103 is pulled to drive the sliding frame 103 and the whiteboard 104 to move out of the shell 101. During the movement of the sliding frame 103, the locking column 201 is driven to rise. When the locking column 201 is aligned with the locking groove on the shell 101, the locking column 201 extends into the locking groove under the action of the locking spring 202, thereby locking the sliding frame 103 and the whiteboard 104. At this time, the teacher can write on the blackboard through the whiteboard 104; when one of the whiteboards 104 is full of writing, the teacher presses the button 205 to allow the full whiteboard 104 to fall into the shell 101. The whiteboard 104 can be stored in the housing 101, and then the other whiteboard 104 can be pulled out. Not only does it not need to erase the writing on the whiteboard 104, but the blackboard writing can also be saved, which is convenient for reviewing the previous blackboard writing. When the teaching is over, all the sliding frames 103 and the whiteboards 104 are put into the housing 101, and then the threaded rod 105 is rotated to drive the moving plate 106 and the erasing board 107 to move, so that the erasing board 107 is in contact with the whiteboard 104. In this way, when the teacher pulls out the sliding frame 103 and the whiteboard 104 next time, the erasing board 107 can erase the writing on the whiteboard 104, thereby avoiding wasting time on erasing the blackboard writing and facilitating the review of the previous blackboard writing content.
