The connecting shell 25 can be rotated to adjust the lateral angle of the display screen body 210. The universal wheel 32 is moved, and the handle 35 is twisted to drive the second rotating disk 34. The second rotating disk 34 drives the threaded cylinder 36. The threaded cylinder 36 rotates to screw out the threaded rod 37. The threaded rod 37 drives the connecting plate 38. The connecting plate 38 is limited by the limiting rod 39. At the same time, the connecting plate 38 drives the rubber pad 310 to descend, so that the rubber pad 310 contacts the ground and generates friction with the ground, thereby positioning the position of the positioning device.

[0029] Through the above steps, the first rotating disk 22 is rotated inside the box body 1, so that the connecting shell 25 is rotated to adjust the lateral rotation angle of the display screen body 210, and the direction of the display screen body 210 can be adjusted. The spring 24 pushes the block 23 to position the angle of the display screen body 210 to solve the problem that the lateral angle of the display screen is fixed, and it is inconvenient for the teacher to observe the display screen when lecturing at an angle to the side of the display screen.
