[0024] Specifically, first remove the gas filling gun 23, then use the controller 22 to start the motor 7, the motor 7 drives the driving shaft 8 to rotate, and the driving shaft 8 drives the storage tray 10 to rotate to release the second connecting tube 11. Because the first connecting tube 20 and the second connecting tube 11 are rotatably connected, and the connection is in the horizontal direction of the central axis of the storage tray 10, the storage tray 10 will not affect the first connecting tube 20 and the second connecting tube 11 when rotating to release the line. At the same time, the reciprocating screw rod 16 will be driven to rotate through the first pulley 12, the second pulley 13 and the driven shaft 14, so that the adjusting rod 18 and the releasing position of the second connecting tube 11 on the storage tray 10 are in a vertical direction. Then the worker holds the gas filling gun 23 to pull the second connecting tube 11 outward until the gas filling gun 23 is put into the gas filling place of the car, and then stops the rotation of the motor 7, and then uses the controller 2 The gas tank 21 is started, and the gas tank 21 delivers natural gas to the first connecting pipe 20 and enters the second connecting pipe 11, and enters the car through the gas gun 23. When the natural gas is full, the gas gun 23 is put back to its original position, and the motor 7 is started to reverse. The motor 7 drives the storage tray 10 to rotate through the driving shaft 8, and the storage tray 10 will reel in the second connecting pipe 11. At the same time, the driving shaft 8 drives the first pulley 12 to rotate, and the first pulley 12 drives the second pulley 13 to rotate through the transmission belt. The second pulley 13 drives the reciprocating screw rod 16 to rotate through the driven shaft 14, thereby driving the moving block 17 to rotate, and then driving the adjusting rod 18 to move. When the adjusting rod 18 moves, it drives the second connecting pipe 11 in the inner wall to move, so that the position of the storage tray 10 to store the second connecting pipe 11 is adjusted.

[0026] Specifically, when used for a long time, the box body 1 needs to be maintained. At this time, you only need to pull the insertion rod 5 upward to make the insertion rod 5 separate from the inner wall of the swing arm 3, and then turn the swing arm 3 to the right to make the swing arm 3 leave the front end of the front cover 2. Then the front cover 2 can be opened, and then the internal maintenance and repair can be carried out to keep the device in good working condition for a long time.

[0027] Working principle: When in use, first remove the gas gun 23, then use the controller 22 to start the motor 7, the motor 7 drives the driving shaft 8 to rotate, thereby driving the storage tray 10 to rotate and release the second connecting pipe 11. At this time, the worker pulls the second connecting pipe 11 outward until the gas gun 23 is placed in the gas filling place of the car, then stops the rotation of the motor 7, and then uses the controller 22 to start the gas tank 21. The gas tank 21 allows natural gas to enter the second connecting pipe 11 from the first connecting pipe 20, and enters the car through the gas gun 23. When the natural gas is full, put the gas gun 23 back to its original position, start the motor 7 to reverse and rewind, and the motor 7 drives the storage tray 10 through the driving shaft 8. The second connecting tube 11 is wound up, and at the same time, the driving shaft 8 will drive the first pulley 12 to rotate, and the first pulley 12 drives the second pulley 13 to rotate through the transmission belt, and the second pulley 13 drives the reciprocating screw 16 to rotate through the driven shaft 14, thereby driving the moving block 17 to rotate, and then driving the adjusting rod 18 to move, and the adjusting rod 18 will move left and right to adjust the position of the second connecting tube 11 when it is stored.
