The left side of the elastic steel bar 23 is fixedly connected to a rubber fitting block 25, and the left side of the rubber fitting block 25 is movably connected to the right side of the fixed ring seat 21. The pull rod 24 is manually pulled to the right, causing the elastic steel bar 23 to produce elastic deformation to the right, so that the static friction between the rubber fitting block 25 and the fixed ring seat 21 disappears, and then the fixed ring seat 21 is manually rotated to adjust the elevation angle of the whiteboard in the inner cavity of the whiteboard positioning frame 26, and then the pull rod 24 is released, and the deformation of the elastic steel bar 23 is reset to complete the locking of the overall elevation angle of the whiteboard positioning frame 26.

[0023] As an implementation method in this embodiment, Figure 3 As shown, a whiteboard positioning frame 26 is fixedly installed on the left side of the rotating shaft 22, a rubber strip 261 is fixedly connected to the back of the inner wall of the whiteboard positioning frame 26, a bolt member 262 is threadedly connected to the front of the whiteboard positioning frame 26, the back of the bolt member 262 extends into the inner cavity of the whiteboard positioning frame 26 and is rotatably connected to a circular plate 263, a circular rubber pad 264 is fixedly connected to the back of the circular plate 263, the whiteboard is inserted into the inner cavity of the whiteboard positioning frame 26, and the bolt member 262 is rotated to move the circular plate 263 backward, thereby completing the fixing of the whiteboard, and through the cooperation of the circular rubber pad 264 and the rubber strip 261, the problem of serious squeezing damage to the whiteboard during the fixing process can be avoided.

[0024] As an implementation method in this embodiment, Figure 4-5 As shown, the height adjustment mechanism 3 includes a square tube 31, and an extended square column 32 is detachably connected to the inner wall of the square tube 31. A through hole 33 is opened on the right side of the square tube 31 and the extended square column 32. A pin 34 is movably inserted in the inner cavity of the through hole 33. A magnetic block 35 is fixedly installed on the inner wall of the pin 34. The left side of the magnetic block 35 is movably connected to the right side of the square tube 31.

[0025] Working principle: During use, the two structures cooperate to support the whiteboard. First, the whiteboard is inserted into the inner cavity of the whiteboard positioning frame 26, and then the bolt 262 is rotated to drive the circular plate 263 to move backward to complete the fixing of the whiteboard. If the elevation angle of the whiteboard needs to be adjusted, the pull rod 24 is manually pulled away from the fixed ring seat 21, and then the fixed ring seat 21 is manually rotated to adjust the elevation angle of the whiteboard in the inner cavity of the whiteboard positioning frame 26.

[0026] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
