The top of the base plate 1 is fixedly connected to the placement frame 2, and the top of the placement frame 2 is slidably connected to the display screen 3, the top front side and left and right sides of the base plate 1 are fixedly connected to pairs of air cylinders 6, the long board 4 is fixedly connected between the output ends of the paired air cylinders 6 on the front side, the short board 401 is fixedly connected between the output ends of the paired air cylinders 6 on the left and right sides, and the needle 5 is fixedly connected between the paired short boards 401, the top front side of the base plate 1 is fixedly connected to the power supply 502, and the connecting line 501 is fixedly connected between the power supply 502 and the needle 5, the bottoms of the long board 4 and the short board 401 are fixedly connected to soft air bags 8, and the placement frame 2 is provided with an injection mechanism.

[0029] like Figure 3-Figure 6 As shown, the air injection mechanism includes a hose 7, a short fan 9 and a connecting frame 10. The short fan 9 is fixedly connected to the bottom of the placement frame 2, and a pair of connecting frames 10 are fixedly connected to the front side and the left and right sides of the bottom of the placement frame 2. The hose 7 is slidably connected between the pairs of connecting frames 10. One end of the hose 7 is connected to the short fan 9, and the other end of the hose 7 is connected to the adjacent soft air bag 8.

[0030] like Figure 7 and Figure 8 As shown, it also includes a bevel frame 11, a rounded plate 12, a connecting shaft 13 and a torsion spring 14. The rounded plate 12 distributed axially is fixedly connected to the rear side of the top of the long plate 4. The connecting shaft 13 is rotatably connected to the rear side of the rounded plate 12. A pair of torsion springs 14 are fixedly connected between the rounded plate 12 and the connecting shaft 13. The bevel frame 11 is fixedly connected between the axially distributed connecting shafts 13.

[0031] like Fig. 9 and Fig.10 As shown, it also includes a long fan 15, an air duct 16, a thick plate 1601 and a sensor 17. The long fan 15 is fixedly connected to the top rear side of the bottom plate 1, and the thick plates 1601 are fixedly connected to the left and right parts of the rear side of the placement frame 2.

[0034] When the worker needs to detect the lighting of the FOG LCD screen, the entire fixture can be powered on first. At this time, since the sensor 17 is not blocked by the bevel frame 11, the sensor 17 will start the long fan 15 to spray air from the air duct 16 and clean the dust on the surface of the placement frame 2. Then the display screen 3 is placed on the placement frame 2. At this time, the long fan 15 is still in the on state, so the gas sprayed from the air duct 16 will also clean the dust and other impurities on the surface of the display screen 3. Then the cylinder 6 is started to drive the long board 4, the short board 401, the soft air bag 8 and the bevel frame 11 to move downward until the soft air bag 8 contacts the display screen 3 and clamps it. During this period, the short fan 9 can be started, and air can be injected into the soft air bag 8 through the hose 7 to expand the soft air bag 8 and fix the display screen 3 softly. Moreover, when the bevel frame 11 moves downward to When the sensor 17 is blocked, the sensor 17 turns off the long fan 15 to avoid wasting resources. After that, the display screen 3 can be lit up and tested through the needle 5. After the test is completed, the cylinder 6 is started to drive the long board 4, the short board 401, the soft air bag 8 and the bevel frame 11 to move upward and reset. Then the display screen 3 is taken out and the power is turned off. During this period, the bevel frame 11 is always in a closed state to prevent debris from falling and damaging the display screen 3. People can also understand the lighting status of the display screen 3 through the observation window on the bevel frame 11. Only when the cylinder 6 and the needle 5 and other components are damaged, people turn the bevel frame 11 upward and repair the cylinder 6 and the needle 5 and other components. The torsion spring 14 is deformed immediately. After the repair or replacement is completed, the bevel frame 11 is released, and the bevel frame 11 rotates in the opposite direction and resets under the action of the torsion spring 14 and gravity.
