A silicone block 25 is fixedly connected to the top of the fixed block 23. The silicone block 25 limits the bottom plate 26 to prevent excessive displacement. A fixed plate 11 is fixedly connected to the outside of the backrest 12. The fixed plate 11 provides auxiliary support for the backrest 12, allowing it to operate more stably. A groove 13 is provided on the outside of the backrest 12. A guardrail 18 is fixedly connected to the inside of the backrest 12. The groove 13 allows the support mechanism to be installed on the inside of the backrest 12. The guardrail 18 provides support for the support mechanism, allowing it to operate stably.

[0040] Working principle: When the position of the backrest 14 needs to be adjusted, it can be moved by pulling it, which moves the top plate 28, which in turn moves the bottom plate 26. The bottom plate 26 moves the fixing block 23, which in turn moves the connecting plate 21 and the connecting plate 20, thus forming a cross shape between the connecting plate 21 and the connecting plate 20, thereby supporting the backrest 14. The fixing block 23 moves the sliding plate 38 in the middle of the connecting plate 37, which in turn moves the locking block 34, causing the locking block 34 and the locking groove 33 on the connecting plate 37 to engage with each other, thus fixing the backrest 14 and preventing it from shifting when the user uses it.

[0041] When it is necessary to adjust the angle between the seat 1 and the backrest 12, the angle adjuster 9 can be activated by pulling the handle 7, so that the backrest 12 can rotate along the pivot 10, thereby adjusting the angle of the backrest 12. When it is necessary to adjust the height of the gaming chair, the pneumatic push rod 2 can be activated to adjust the height of the gaming chair.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
