[0025] See also Figures 1 to 8 When the cam 2 is in the upright position, the movable jaw 4 is moved to the left of the upright position and the movable jaw 4 is moved to the right of the upright position.

[0026] In one embodiment, specifically, the heat dissipation assembly includes a ventilation cavity 6 opened inside the fixed base 1, an air inlet 7 is opened on the fixed base 1, a hair dryer 8 is provided on the air inlet 7, and an air outlet 9 is opened on the fixed base 1. The ventilation cavity 6 is opened inside the fixed base 1, the air inlet 7 is opened on the outer wall of the fixed base 1 and is connected with the ventilation cavity 6, the hair dryer 8 is fixedly installed on the air inlet 7, and the air outlet 9 is opened on the outer wall of the fixed base 1 opposite to the air inlet 7, and the air outlet 9 is connected with the ventilation cavity 6. The hair dryer 8 can blow wind into the ventilation cavity 6 through the air inlet 7, and the wind blown out from the air outlet 9 can blow onto the display to dissipate heat for the display.

[0027] Among them, the air outlet 9 is provided with a fixed shaft 10, and the fixed shaft 10 is provided with a flap 11. The fixed shaft 10 is fixedly installed between the inner walls on both sides of the air outlet 9, and the flap 11 is hinged on the fixed shaft 10. Rotating the flap 11 can adjust the air outlet angle of the air outlet 9, which is convenient for heat dissipation of monitors of different sizes, and can adjust the position of the wind blowing on the monitor after the monitor is raised or lowered.

[0028] On the basis of the above embodiment, specifically, the adjustment component includes a connecting block 12 mounted on the fixed seat 1, the connecting block 12 is provided with an adjusting groove 13, the connecting block 12 is provided with an active cavity 14, the connecting block 12 is slidably connected to the plug rod 15, the plug rod 15 is provided with a boss 16, the boss 16 is slidably connected to the active cavity 14, a spring 17 is provided in the active cavity 14, the adjusting groove 13 is slidably connected to the fixing plate 18, the fixing plate 18 is provided with a socket 19 corresponding to the plug rod 15, the connecting block 12 is fixedly mounted in the middle of the outer wall of the fixing seat 1, and the adjusting groove 13 is provided on the connecting block 12. On the connecting block 12, the movable cavity 14 is opened on the side wall of the connecting block 12, the insertion rod 15 is slidably connected to the connecting block 12, the boss 16 is integrally formed on the insertion rod 15 and is located inside the movable cavity 14, which can prevent the insertion rod 15 from detaching from the connecting block 12, and the spring 17 is sleeved on the insertion rod 15 and is located between the boss 16 and the inner wall of the movable cavity 14, which can push the connecting rod into the adjustment groove 13, and the fixed plate 18 is slidably connected to the adjustment groove 13, which can facilitate the adjustment of the height of the fixed plate 18. A plurality of holes 19 are opened on the side wall of the fixed plate 18, and the insertion rod 15 is inserted into the hole 19 to fix the height of the fixed plate 18.

[0029] Furthermore, a pull ring 20 is provided at one end of the insertion rod 15 and located on the outside of the fixing seat 1. The pull ring 20 is fixedly installed at one end of the insertion rod 15 and is located on the outside of the connecting block 12. Pulling the pull ring 20 can pull the insertion rod 15 out of the socket 19, which is convenient for adjusting the height of the fixing plate 18, thereby adjusting the height of the display, and also convenient for disassembling the fixing plate 18 and the display.

[0030] In one embodiment, specifically, the fixed plate 18 is provided with a support plate 21, and the fixed plate 18 is provided with a movable groove 22, and a pressure plate 23 is provided in the movable groove 22, and a sliding rod 24 is provided in the sliding groove 3, and a spring 25 is provided on the sliding rod 24. The support plate 21 is integrally formed at the bottom of the fixed plate 18, and the movable groove 22 is provided at the upper part of the fixed plate 18. The pressure plate 23 is slidably connected to the movable groove 22. The display can be fixed by clamping it between the support plate 21 and the pressure plate 23. Sliding the pressure plate 23 up and down can change the distance between the support plate 21 and the pressure plate 23, which is convenient for fixing displays of different sizes. The sliding rod 24 is fixedly connected between the upper and lower inner walls of the movable groove 22. The spring 25 is sleeved on the sliding rod 24 and is located above the pressure plate 23, which can push the pressure plate 23 downward, so that the display can be fixed more firmly and prevent the display from falling.

[0031] Furthermore, the interior of the ventilation cavity 6 is provided with an air guide plate 1 26, and the ventilation cavity 6 is provided with an air guide plate 2 27. The air guide plate 1 26 is fixedly installed in the middle of the ventilation cavity 6 and faces the air inlet 7. It can divert the wind blown in from the air inlet 7 to the two air outlets 9. The air guide plate 27 is fixedly installed at the air outlet 9. The air guide plate 1 26 and the air guide plate 2 27 can prevent the wind from blowing directly on the inner wall of the ventilation cavity 6, avoid airflow disturbance, make the wind pass through the ventilation cavity 6 more smoothly, and improve the heat dissipation effect.

[0032] When in use, place the fixed claw 2 and the movable claw 4 on both sides of the headrest support rod, then tighten the bolt 5, and the movable claw 4 moves closer to the fixed claw 2. After tightening the bolt 5, the movable claw 4 and the fixed claw 2 clamp the support rod of the headrest. At this time, the device is fixed on the support rod of the headrest. Then, clamp the upper end of the display inside the pressure plate 23 and push the pressure plate 23 upward. The pressure plate 23 moves upward in the movable groove 22. Then, clamp the lower end of the display on the support plate 21. At the same time, the spring 25 presses the pressure plate 23 downward to fix the display. When the display needs to be cooled, start the hair dryer 8, and the wind blown by the hair dryer 8 enters through the air inlet 7. After entering the ventilation cavity 6, the wind goes along the wind guide plate 1 26 and the wind guide plate 2 27 to the air outlet 9. Then, the wind blows through the air outlet 9 to the back of the monitor to dissipate heat for the monitor. When the height of the monitor needs to be adjusted, pull the pull ring 20 outward, and the insertion rod 15 is disengaged from the socket 19. Then, adjust the monitor to an appropriate height and release the pull ring 20. Then, slightly move the monitor up and down so that the insertion rod 15 is inserted into the socket 19. At this time, the height adjustment of the monitor is completed. After the height adjustment is completed, the position where the wind from the air outlet 9 blows to the monitor changes. At this time, turn the flap 11 to adjust the wind direction of the air outlet 9 to achieve better heat dissipation effect.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
