And 4, step 4: after the use is finished, the wrench tool is matched with the gear square tenon of the middle gear and rotates reversely, the telescopic support rod of the supporting device is adjusted to be telescopic to the shortest length, the storage is convenient, and the supporting device is taken out of the ship stern tube to finish the operation.
