[0025] The sealing airbag 10 is used to cover the gap between the connecting frame 3 and the gas tank 1, so that the sealing effect between the two is better, and the connecting frame 3 and the structure required for installation are covered to achieve an anti-theft effect; the limiting pressure block 8 cooperates with the placement groove 6 to prevent the connecting frame 3 from moving horizontally relative to the mounting seat 2. The air pressure change in the telescopic air cylinder 11 is reflected as its extension or shortening. When the movable top plate 12 moves, the position of the connecting frame 3 can be pushed and adjusted to keep the connecting frame 3 corresponding to the position of the mounting seat 2.

[0026] The movable clamping device 5 comprises a limit block 51 , a side surface of the limit block 51 is connected to a moving rod 52 , and the other end of the moving rod 52 is connected to a moving magnetic plate 53 .

[0027] The limit block 51 cooperates with the limit groove 4 to realize the vertical limit of the connecting frame 3 and the mounting seat 2, and the inclined surface of the limit block 51 is used to be squeezed by the mounting seat 2 when it moves downward, which is convenient for the automatic assembly limit of the connecting frame 3. The movable magnetic plate 53 is used, and the movement of the movable magnetic plate 53 can be controlled by a magnet with opposite magnetic properties on the outside of the connecting frame 3, without direct manual contact with the movable magnetic plate 53;

[0028] The movable top plate 12 is overlapped in the connecting frame 3 , the limiting pressing block 8 is set to be circular, and the sealing airbag 10 is set on the gas storage tank 1 .

[0029] The limit block 51 is slidably arranged in the limit groove 4, the outer sleeve of the moving rod 52 is provided with a guide sleeve 54, the guide sleeve 54 is connected under the connecting frame 3, the moving magnetic plate 53 is slidably arranged under the connecting frame 3, and the outer sleeve of the moving rod 52 is provided with a first elastic component 55 connected to the guide sleeve 54 and the moving magnetic plate 53.

[0030] The first elastic component 55 is used to control the limit block 51 to automatically enter the limit groove 4 after the limit block 51 moves to the position corresponding to the limit groove 4, and the elastic force can prevent the limit block 51 from shaking at will;

[0031] The piston extrusion device 7 includes a piston cylinder 71 , which is connected to the placement groove 6 , and a piston plate 72 is slidably provided in the piston cylinder 71 . The side of the piston cylinder 71 is connected to the connecting pipe 9 at a position below the piston plate 72 .

[0032] The piston cylinder 71 cooperates with the piston plate 72. When the piston plate 72 moves, it is used to suck the gas in the sealing airbag 10 and the telescopic air cylinder 11 into the piston cylinder 71, or squeeze the gas in the piston cylinder 71 and transfer it to the telescopic air cylinder 11 or the sealing airbag 10;

[0033] The piston plate 72 is connected to a piston rod 73 , the top end of the piston rod 73 is connected to a contact plate 74 , and the contact plate 74 is overlapped under the limiting pressure block 8 .

[0036] The second elastic component 75 controls the piston plate 72 to return to its original position when the contact plate 74 loses its compression.

[0037] The working principle of the utility model is:

[0038] When the connecting frame 3 needs to be disassembled, a magnet with opposite magnetic properties to the movable magnetic plate 53 is directly placed at a corresponding position in the connecting frame 3, and then the movable magnetic plate 53, the movable rod 52 and the limit block 51 are controlled by the magnetic force between the two to move away from the limit slot 4, the limit block 51 is separated from the limit slot 4, and then the connecting frame 3 can be taken out upwards;

[0039] When it is necessary to assemble the connecting frame 3, the connecting frame 3 is directly moved downward, and the inclined portion of the mounting seat 2 guides the connecting frame 3 to move downward. The limiting pressure block 8 controls the contact plate 74 and the piston plate 72 to move downward, and the mounting seat 2 squeezes the limiting block 51 to move. When the piston plate 72 moves, the gas in the piston cylinder 71 is squeezed and transferred to the sealing air bag 10 and the telescopic air cylinder 11 through the connecting pipe 9 and the air pipe respectively. The sealing air bag 10 expands and contacts the gas storage tank 1, and the telescopic air cylinder 11 extends to control the moving top plate 12 to push the connecting frame 3 to adjust its position. When the limiting block 51 moves to the position corresponding to the limiting groove 4, the first elastic component 55 controls the moving rod 52 and the limiting block 51 to reset, and the limiting block 51 is inserted into the limiting groove 4 to complete the assembly of the connecting frame 3.
