[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Depend on Figure 1-5The utility model comprises an embedded block 1 and a monitor 5. A square groove 2 is provided on the top of the embedded block 1. A mounting plate 3 matching its size is arranged in the groove 2. A vertical column 4 is fixedly installed at the middle position of the top of the mounting plate 3. The monitor 5 is fixedly installed on the side wall at the top of the column 4. Slots 6 are provided at the corners on both sides of the mounting plate 3. Plate grooves 7 are provided at the corners on both sides of the groove 2. A plug-in plate 8 is movably inserted in each plate groove 7. One end of the four plug-in plates 8 extends out of the plate groove 7 and is respectively inserted into the corresponding slots 6 on both sides of the mounting plate 3. Passages are provided on the tops of the four plug-in plates 8 at one end in the plate groove 7. Hole 9, a screw hole 10 connected to the four plate grooves 7 is opened at the top of the embedded block 1, and bolts 11 are threadedly inserted in the four screw holes 10. The four bolts 11 all penetrate the screw holes 10 and are respectively inserted in the through holes 9 on the corresponding plug plates 8. The embedded block 1 is poured with concrete to fix its position, and then the mounting plate 3 is placed in the groove 2 at the top of the embedded block 1, and then the connecting blocks 13 in the four notches 12 are moved so that one end of the four plug plates 8 are respectively inserted into the corresponding card slots 6 on both sides of the mounting plate 3. Finally, the bolts 11 are used to penetrate the screw holes 10 and inserted into the through holes 9 on the plug plates 8 to complete the fixed installation of the mounting plate 3.
