The inner wall of the storage groove 103 is fixedly connected to the top of the air cushion 104. One side of the air cushion 104 is fixedly connected to one end of the inflation nozzle 105.

[0018] Specifically: an inflation device is used to inflate the air cushion 104 through the inflation nozzle 105. The device is affected by additional buoyancy. Then, the fixed base 101 is moved to the installation location. The air cushion 104 increases the additional buoyancy, which facilitates the overall movement of the fixed base 101 and the adjustment of the installation position.
