The screen 2 is installed between the frames 1. Both ends of the surface of the frame 1 are opened with a plurality of positioning holes 3-2. A pressure plate 3-3 is installed in the bottom groove 3-1. A plurality of plug blocks 3-4 are arranged on the bottom surface of the pressure plate 3-3. The plug blocks 3-4 are plugged and connected in the positioning holes 3-2. The pressure plate 3-3 is fixedly connected to the bottom groove 3-1 by bolts.

[0032] In the present embodiment, in order to realize the effect that the screen plate 2 can be disassembled and replaced separately, a fixing component 3 is designed, a bottom groove 3-1 is opened at the bottom of the frame 1, the screen plate 2 is placed between the frames and in the bottom groove 3-1, a positioning hole 3-2 is opened on the surface of the screen plate 2, a pressure rod is installed in the bottom groove 3-1, the pressure rod is connected in the bottom groove 3-1 by bolts, and is pressed on the surface of the screen plate 2, an insert block 3-4 is arranged at the bottom of the pressure plate 3-3, the insert block 3-4 is inserted in the positioning hole 3-2, and is used to position and install the screen plate 2 so that it will not fall off.

[0033] Furthermore, the docking assembly 4 includes an outer groove 4-1, which is opened on the outer surface of the frame 1, and connecting holes 4-2 are opened on the opposite end surfaces of the outer groove 4-1. A connecting piece 4-3 is inserted and connected in the outer groove 4-1, and a pair of long cavities 4-4 are opened at both ends of the connecting piece 4-3. A round rod 4-5 is movably connected in the long cavity 4-4, and the round rod 4-5 is inserted and connected in the connecting hole 4-2. A spring 4-6 is installed in the long cavity 4-4. The round rod 4-5 has the same diameter as the connecting hole 4-2 to form a seamless connection structure.

[0034] In this embodiment, in order to achieve the effect of interconnecting multiple screens 2, a docking assembly 4 is designed, an outer groove 4-1 is opened on the outside of the frame 1, and connecting holes 4-2 are opened at both ends of the outer groove 4-1. A connecting piece 4-3 is also provided, and a long cavity 4-4 is opened at both ends of the connecting piece 4-3. The movable set inside the long cavity 4-4 is connected to a round rod 4-5, and a spring 4-6 is arranged inside. The round rod 4-5 can be retracted into the long cavity 4-4, and the connecting rod 5-3 is plug-connected with the connecting hole 4-2 through the round rod 4-5, so as to connect multiple screens 2 to each other.
