[0032] The working principle and usage process of the present invention are as follows: when in use, the user first drives the gas pressure rod body 20, and the gas pressure rod body 20 unfolds to drive the lifting sliding wheel 18 to move in the slide rail of the base frame 1, so that the fulcrum of the gas pressure rod body 20 moves backward. By moving the fulcrum of the gas pressure rod body 20 backward, the angle of lifting the frame 3 becomes steeper, and then the lifting motor 8 is driven to lift. The lifting motor 8 drives the lifting frame 2 to lift upward, and the lifting frame 2 drives the support frame 15 to move forward, so that the fulcrum of the support frame 15 moves forward. By pushing the frame 3 to lift at a steeper angle and moving the fulcrum of the support frame 15 forward, the occupied space is reduced, thereby achieving the purpose of a good folding effect.

[0033] To sum up: the pneumatic rod support structure, through the expansion of the pneumatic rod body 20, drives the lifting sliding wheel 18 to move in the slide rail of the base frame 1, so that the fulcrum of the pneumatic rod body 20 moves backward, making the lifting angle of the frame 3 steeper, and then drives the lifting motor 8 to lift, and the lifting motor 8 drives the lifting frame 2 to lift upward, and the lifting frame 2 drives the support frame 15 to move forward, so that the fulcrum moves forward, thereby achieving the purpose of good folding effect, and solving the problem that the existing pneumatic rod support structure has no folding function.
