If the gap between the power supply module 5 and the power receiving module 6 needs to be reduced, the adjusting nut 12 is pushed by a tool to rotate clockwise, the adjusting nut 12 drives the power supply shell 51 to move towards the direction close to the power receiving shell 61, and the gap between the power supply module 5 and the power receiving module 6 is measured by stretching into the caliper through the observation hole 103. When the gap between the power supply module 5 and the power receiving module 6 reaches the expected value, the pushing of the adjusting nut 12 is stopped, and then the sealing cover 14 is mounted on the avoiding hole.
If the gap between the power supply module 5 and the power receiving module 6 needs to be increased, the adjusting nut 12 is pushed by a tool to rotate anticlockwise, the adjusting nut 12 drives the power supply shell 51 to move in the direction away from the power receiving shell 61, and the gap between the power supply module 5 and the power receiving module 6 is measured by stretching into the caliper through the observation hole 103. When the gap between the power supply module 5 and the power receiving module 6 reaches the expected value, the pushing of the adjusting nut 12 is stopped, and then the sealing cover 14 is mounted on the avoiding hole.
