[0054] like Figure 2 As shown, a positioning block 10 is provided on one side of the positioning flip plate 9; the positioning block 10 enables faster location of the notch for positioning, making installation more convenient.

[0055] like Figure 2 As shown, a groove 4 is provided on the mounting strip, and a positioning slide plate 5 is provided in the groove 4. The groove 4 is located on the side of the positioning flip plate 9 away from the positioning block 10. After the positioning slide plate 5 is set, it can slide and fasten one side of the LCD display on the mounting strip. Then, the fixing flip plate 8 is used to fix other loose and unfixed components, so that the LCD screen can be fixed securely and prevent damage.
