[0018] The new practical has the beneficial effects:

[0019] 1. The push force is applied by adjusting the handle to push the arc-shaped sliding block to slide along the preset arc-shaped sliding rail track. The arc-shaped sliding block drives the connecting rod to synchronously displace in the sliding process through the mechanical connection relationship. The connecting rod further links the air guide arc plate and the air cutting plate to adjust the azimuth of the whole arc-shaped sliding rail. When the air guide arc plate and the air cutting plate are rotated to face the wind direction, the air guide arc plate forms a wind barrier through the specially designed arc-shaped curved surface structure to block the direct impact of strong wind and guide the airflow in the vertical direction to the lower part for shunting, thereby achieving the dual functions of efficient wind resistance control and airflow guidance.

[0020] 2. The connecting plate is moved to the working position flush with the top surface of the platform panel by pushing up and down. In the adjusting process, the limiting block fixed to the connecting plate is synchronously guided to vertically move in the preset sliding groove to ensure the accurate controllable movement track. When the connecting plate reaches the target height, the connecting plate and the platform panel are rigidly fixed by using the bolt. At this time, the relative position of the centering steel pipe and the platform panel is simultaneously constrained by the special structure of the connecting plate to form a stable limiting system of three-point positioning. The structure supports real-time unlocking of the bolt and re-adjustment of the clamping height of the connecting plate according to the actual installation height of the platform panel to realize the dynamic centering adjustment function suitable for different working conditions.
