[0032] Reference Figure 1-3 There are two pull rods 7 slidingly connected inside the public notice board 3. The function of the pull rod 7 is to pull the pull rod 7 to drive the connecting rod 8 to rotate. The outer bottom of the pull rod 7 is rotatably connected with a connecting rod 8. The function of the connecting rod 8 is to rotate and drive the limit block 9 to slide. The end of the connecting rod 8 away from the pull rod 7 is rotatably connected to the limit block 9. The function of the limit block 9 is to limit the pull rod 7. The bottom of the limit block 9 is fixedly connected with a spring 10. The function of the spring 10 is to provide power during the reset movement.

[0033] Reference Figure 3 , by pulling the pull rod 7 and placing the mounting block 4 on the notice board 3 to be assembled inside the positioning hole 6, pulling the pull rod 7 drives the connecting rod 8 to rotate, and the rotation of the connecting rod 8 drives the limit block 9 to slide, and the limit block 9 slides to squeeze the spring 10. The mounting assembly includes two mounting blocks 4. The function of the mounting blocks 4 is to position the assembled notice board 3 by engaging with the positioning hole 6. The left side of the mounting block 4 is fixedly connected to the right side of the notice board 3. Its function is to fix the mounting block 4, so as to facilitate the assembly of the notice board 3. A fixing hole 5 is opened inside the mounting block 4. The function of the fixing hole 5 is to fix the mounting block 4 by engaging with the pull rod 7.

[0034] Reference Figure 1-3 When the mounting block 4 is completely engaged with the positioning hole 6, by loosening the pull rod 7, the spring 10 is reset due to the extrusion, thereby pushing the limit block 9 to slide, and the sliding of the limit block 9 drives the connecting rod 8 to rotate so that the pull rod 7 slides and engages with the fixing hole 5 to fix the mounting block 4. The engagement between the mounting block 4 and the positioning hole 6 is used to facilitate the positioning of the combined notice column 3. The pull rod 7 penetrates the notice column 3 and engages with the fixing hole 5. Its function is to facilitate the fixing of the mounting block 4 through the pull rod 7, and then fix the combined notice column 3. The end of the spring 10 away from the limit block 9 is fixedly connected to the inner wall of the notice column 3, and the spring 10 is fixed to prevent the spring 10 from rotating.

[0035] Reference Figure 1 , Figure 2 and Figure 4The four corners of the bottom of the bottom plate 1 are fixedly connected to a shell 12, and the function of the shell 12 is to limit the items inside it. The bottom of the shell 12 is fixedly connected to a cone foot 13, and the function of the cone foot 13 is to support the bottom plate 1. Two through holes 17 are provided on the outside of the shell 12, and the function of the through holes 17 is to facilitate the penetration of the supporting feet 16. The inside of the shell 12 is rotatably connected to a screw rod 14, and the function of the screw rod 14 is to rotate and drive the slider 15 to slide.

[0036] Reference Figure 4 The outer side of the screw rod 14 is threadedly connected with a slider 15. The function of the slider 15 is to slide and drive the supporting feet 16 to rotate. The upper outer side of the slider 15 is rotatably connected to two supporting feet 16. The function of the supporting feet 16 is to support the base plate 1 and increase the friction force. The slider 15 slides and drives the supporting feet 16 to rotate along the through hole 17. When the through hole 17 is rotated to contact the ground and the handle 18 cannot be rotated, the base plate 1 is fixed. There are four rotating shafts 11 rotatably connected inside the base plate 1. The function of the rotating shaft 11 is to rotate and drive the screw rod 14 to rotate.

[0037] Reference Figure 4 The bottom of the rotating shaft 11 is fixedly connected to the upper part of the screw rod 14, and its function is to facilitate the rotation of the rotating shaft 11 to drive the screw rod 14 to rotate. By placing the notice board 3 on the ground and turning the handle 18, the handle 18 rotates to drive the rotating shaft 11 to rotate, the rotating shaft 11 rotates to drive the screw rod 14 to rotate, and the screw rod 14 rotates to drive the slider 15 to slide. The upper side of the rotating shaft 11 is fixedly connected with the handle 18, and the function of the handle 18 is to facilitate the rotation of the rotating shaft 11. The support foot 16 passes through the through hole 17 and is arranged inside the through hole 17, and its function is to facilitate the support foot 16 to support the bottom plate 1.

[0038] Working principle: When the notice board 3 needs to be used to publicize data, the notice board 3 is placed on the ground and the handle 18 is turned. The handle 18 rotates to drive the shaft 11 to rotate. The shaft 11 rotates to drive the screw rod 14 to rotate. The screw rod 14 rotates to drive the slider 15 to slide. The slider 15 slides and drives the support foot 16 to rotate along the through hole 17. When the through hole 17 rotates to contact the ground and the handle 18 cannot rotate, the bottom plate 1 is fixed. After the bottom plate 1 is fixed, the data can be publicized. When there is too much data, the notice board 3 cannot display the data. When the announcement is fully carried out, pull the pull rod 7 and place the installation block 4 on the announcement column 3 that needs to be assembled inside the positioning hole 6. Pull the pull rod 7 to drive the connecting rod 8 to rotate. The rotation of the connecting rod 8 drives the limit block 9 to slide. The sliding of the limit block 9 squeezes the spring 10. When the installation block 4 is fully engaged with the positioning hole 6, release the pull rod 7, and the spring 10 is reset due to the squeezing, thereby pushing the limit block 9 to slide. The sliding of the limit block 9 drives the connecting rod 8 to rotate, so that the pull rod 7 slides and engages with the fixing hole 5 to fix the installation block 4.
